Currently not available, please sign up to get notified

Product number: LED521PT70o

Based on the MY-Semi-IC MY9942 a compact DMX receiver with 4 constant current sources (KSQs) for constant current was developed. These are clocked KSQs. The current is fixed on the production side via corresponding resistors. Variants between 300 and 1200mA are offered. With this, different HighPower-LEDs can be operated.

The DMX address can be set by DIP switch and the number of used DMX channels from 1-4 can be set by solder jumper. With one DMX address the 4 outputs are controlled in parallel, with 2 address 2 outputs each.

The board has the size of 40x73mm and is thus suitable for installation in a Strapubox housing.

Scope of delivery:

1x PCB Equipped with all SMD components and DIP switches

Connector depending on version


The currently sold-out models will be available again in the 2nd half of 2020, as the drivers are undergoing a redesign and will then be available in a new variant.
