LED Dimmer / Driver

To dim your LED lighting you need so-called LED driver, such as our universal driver of the LK55 series.

Depending on the installation, you only need a small LK55-2 radio dimmer or the larger variants LK55 or LK55-8 - all listed under CV Driver. These are then accompanied by a selection of classic hand-held remote controls and models for recessed or wall mounting. These include flat pushbuttons, knobs and touch panels. All controls communicate wirelessly with the LK55 LED dimmers, so no additional cable connection is required. Furthermore, a WLAN solution is available with the LK35-8, so you can additionally control your lighting via smartphone or tablet.

A more detailed explanation of the LK55 series can be found below.

Handheld remote controls

Classic handheld remote controls for LK55 and LK35 drivers. Some models are also suitable for multi-zone control. I.e. only 1 remote control can control different drivers separately.

Remote control | 5 zones

Brightness control up to 5 light zones operateable (5 receivers) 1 Channel All remote controls can operate all drivers / receivers of the LK55 series and, if required, also the WiFi driver LK35. It is also possible for several remote controls to operate one driver. E.g. a hand-held remote control and an additional wireless wall panel or several wireless wall panels at different positions in the room. If required, up to 8 remote controls can operate 1 driver. NOTICE: The LK55 remote control for pure dimming should not be used in combination with CCT LED strips (adjustable color temperature) or RGBW LED strips, but only for pure white LED strips with fixed color temperature. Background: When dimming via you would lose all color settings here, because the LED drivers drive all outputs (RGBW or WW/KW) down or up identically. Instead, dim via the appropriate CCT or RGBW remote controls. Technical data: Item no. LK55FB-A3 Power supply 3V CR2025 batteries Dimensions (LxWxH) 134x40x11mm

It is also possible for several remote controls to operate one driver. E.g. a handheld remote control and an additional wireless wall panel or several wireless wall panels at different positions in the room. If required, up to 8 remote controls can operate 1 driver. The range of the radio signal is up to 30m. Visual contact is not necessary. Solid walls made of concrete, brick or similar naturally weaken the radio signal. Power supply: Note that some models are powered by a battery (coin cell) that must be replaced every 1-2 years. This applies to all pushbutton and potentiometer models. All models with touch field can be supplied via the 230V house network, so that no battery change is required. Combination with switch series of well-known manufacturers The housing frame of the controls measures 86x86mm with a depth of 12mm.

Dimmer radio installation module for all light switches

Radio insert module for use with normal light switches (GIRA, MERTEN, BUSCH JÄGER, JUNG etc.) for universal driver of the LK55 series Controllable zones: 1 power supply: 3V CR2430 battery is simply placed in the flush-mounted box With this insert module you can convert ordinary light scanners to a radio control for your LED lighting. The tiny module is connected to the existing light switch and then controlled by it. The module itself, just like all other LK55 remote controls, then sends radio signals to the LK55 LED controller, which takes over the control of the LEDs. This module is the ideal solution if you want to integrate LED lighting into an existing switch/button program and stay within one design line. Simply place the module behind the existing pushbutton in the mounting box, connect the cables and you have an elegant wireless solution for your LED lighting. With a single pushbutton, a long press dims the brightness up or down (always alternating), a short press turns the light on and off. It becomes even more comfortable with a 2-fold pushbutton. In this case, one button dims up, the other button dims down. Switching on and off is done by a short press on both buttons. As usual with the LK55 series, you can also combine several remote controls (several LK55p in different pushbuttons, 3 light pushbuttons and a hand-held remote control, additional app control, etc.). NOTICE: The LK55 remote control for pure dimming should not be used in combination with CCT LED strips (adjustable color temperature) or RGBW LED strips, but only for pure white LED strips with fixed color temperature. Background: When dimming via you would lose all color settings here, because the LED drivers drive all outputs (RGBW or WW/KW) down or up identically. Instead, dim via the appropriate CCT or RGBW remote controls. Technical data: Item no. LK55P Power supply 3V CR2430 batteries Dimensions (BxWxD) 40x40mm, Installation depth: 12mm Operation: The following video shows the operation and installation of the LK55p: The module has 3 connection cables for ON, OFF & COM Connection of the LK55p to a simple wall switch The ON & OFF cables are connected to each other. The pushbutton then takes over the switching on and off (short press in each case) and the dimming up and down (long press in each case). Connection of the LK55p to a double pushbutton The two COM ports of the double pushbutton are connected here. ON & OFF are distributed to the two keys of the double pushbutton. Thus, one button can switch on (short press) and dim up (long press). The second button switches off (short press) and dims down (long press). Note: It is also possible to connect a double pushbutton with two Lk55p so that two separate light zones can be controlled. It is important that there is sufficient space for two LK55p radio modules in the flush-mounted box.

LK55 Driver CV

Dimmer for controlling LED strips and other components with constant voltage.

Radio dimmer LK55-2 | 1 x 8A

The 1 x 8 amp driver offers only one output and is therefore only suitable as a dimmer. Due to the 8 amps, however, very powerful LED components can be connected. At 24 volts, for example, LED components up to 170 watts are possible. The driver is installed between the power supply and the LED component. It is ideally suited for small and medium installations, as well as a supplement for larger installations. The driver belongs to the LK55 series and can be combined with all dimmer remote controls available there. NOTES: All drivers of our LK55 series remember the last setting even in case of power loss. RGBW and CCT color temperature remote controllers have no function on the LK55-2 LED dimmer. Technical data: Voltage: 12V-36V DCPower: Power connection via external switching power supply (not included)Load: 1 x 8A Min. dim level: <1% (for RGB/W <3%)Connection: input: V+/ground, push button; output: V+/groundIP class: IP 20 Dimensions: LxWxH 95x37x20mm Operation via pushbutton input The LK55-2 offers 2 green screw terminals on the back for a button input. For example, a simple pushbutton can be connected to this and thus control the light without radio. Short keystroke switches the LEDs on and off. Long keystroke dims the LEDs up and down. Instead of a pushbutton, in principle only 2 cables can be connected, which are then held together short or long.

LK55 Universal Controller | 4 x 4A

Universal driver with 4 outputs, each capable of carrying 4 amps. When used as a dimmer, 4 parallel outputs are available, which are controlled identically. The designations "RGBW" and "cw" and "ww" can be ignored in this case. When used as a color temperature driver, 2 outputs each are available for warm white ("ww") and cool white ("kw") LEDs. Note the corresponding labeling on the driver. When used as an RGB(W) driver, the 4 outputs take over the separate control of the red (R), green (G), blue (B) and possibly white (W) LEDs. The outputs are labeled accordingly. The driver is installed between the power supply and the LED components (e.g. LED strips, LED panels). Notes: All drivers of our LK55 series remember the last setting even in case of power loss. If you want to operate several light zones independently of each other, several drivers are always necessary. Drivers with several outputs (like here 4 x 4A) are not suitable to operate several zones, because the outputs can only be controlled together (parallel). Technical data: Voltage: 12V-36V DCPower: Power connection via external switching power supply (not included)Load: 4A per output portMin. dim level: <1% (for RGB/W <3%)Connection: input: V+/ground; output: 4x minus,V+IP class: IP20 Dimensions: LxWxH 179x46x22mm Note: The driver has double voltage inputs (++--). For high connected load (> 200 Watt), use our special connection cables for high connected loads (> 200 watts) in order to divide the current load between the two inputs. The large power supplies HLG-480 and HLG-600 already have double voltage outputs, so that both voltage inputs of the driver can be used directly here.

Control via app with the WLAN variant of the LK55 | 4 x 6A

The combined radio/WiFi driver is a classic LK55 with built-in WLAN receiver and sets standards in this field. It can be operated with a radio remote control (LK55 series) or also via smartphone with iOS or Android. Corresponding apps are available: EasyLighting App for Android / für IOS RealColor App for Android / für IOS In the standard version, the receiver has its own integrated access point for WLAN control. However, the receiver can also be set as a WLAN client via an integrated configuration page. This connects the receiver to an existing WLAN at home and provides its services without changing the network. If several cell phones or tablets are used, a simple share function can be used to transfer the learned drivers from one app to another. This means that it is not necessary to retrain the drivers, even if the cell phone is changed, for example. The driver can additionally be operated with remote controls. The hand- and wall controls of the LK55 series are suitable for this purpose. Notes: All drivers of our LK35/55 series remember the last setting even in case of power loss. If you want to operate several light zones independently of each other, several drivers are always necessary. drivers with several outputs (like here 4 x 6A) are not suitable to operate several zones, because the outputs can only be controlled together (parallel).

The universal LK55 Driver

The universal driver/receiver of the LK55 series can be used for any kind of LED installation. The LK55 driver/receiver is always connected between the power supply and the LED lighting (e.g. LED strips).

The LK55 driver always includes a remote control, which you use to control the LK55. Depending on the choice of remote control, the LK55 driver then enables:

a pure brightness control (LED dimmer)
a combined brightness and color temperature control (COLOR TEMPERATURE from warm white to cool white)
a combined brightness and effect color control (RGB or RGBW)

Range:

The radio does not require visual contact and has a range of up to 25m in free field. It also works through lightweight walls, such as plasterboard, through wood, etc.. However, solid walls made of (steel) concrete and thick masonry can block the radio.

These videos show the functions and setup with LK55 driver as LED-only dimmers:

Excursus: Separate LED dimmers or dimmable power supplies?

An alternative to a separate LED dimmer, such as the LK55, are directly dimmable power supplies. This alternative is certainly attractive, since the separate LED dimmer can be saved and a power supply unit is needed anyway. So why not just use a dimmable power supply?

In general, LED Studies advises against dimmable power supplies! In the best case, you can dim the LEDs to a limited extent at most.

Dimmable power supplies on LED strips WITH built-in constant current sources (KSQ)

In modern LED strips with built-in constant current sources (CCS), dimming via power supply usually works only inadequately. The constant current sources on the strip ensure optimal operation of the LEDs, uniform brightness over the entire length of the strip and allow longer installations without power re-supply. If the voltage is now reduced by means of a dimmable power supply, the KSQs compensate for this to a certain extent and the brightness remains the same. If the voltage is too low at some point, the LEDs dim down very quickly. Precise dimming is thus only possible to a limited extent. Translated with www.DeepL.com/Translator (free version)

Dimmable power supplies on LED strips WITHOUT built-in constant current sources (KSQ)

For LED strips without constant current sources, dimming via power supply is only possible to a limited extent and it also only works halfway acceptable (e.g. up to at least 30% brightness) if the power supply is exhausted to its power limit. However, this operation at the power limit also increases the heat generation at the power supply immensely and thus reduces the service life. In general, LED-Studien recommends to use the power supplies only up to 90% of the power limit. The control with a dimmable power supply would completely contradict this recommendation and therefore we advise the solution with a separate LED dimmer.

A separate LED dimmer allows in contrast to dimmable power supplies:

The continuous dimming of the LEDs from 100% to 0% brightness (i.e. switched off).
The safe operation of the power supplies well below the power limit and thus a long service life
The combination with very many variants of radio controls, also for wall mounting
