Eurolite EDX-4RT DMX RDM Truss Pack

It looks and handles well enough but even after returning one unit (thinking it faulty) the second one arrived and it's just as bad.

The total power budget of max 1150W per channel capping out at around 3700W total means that it can be theoretically used (out of the box) to control very basic filament lamps that provide enough resistance to supress it's bad characteristics.

Irrespective of the dimming curve (there are 4 one of which is also "relay mode" (yeah... not really)) set the leaking current is strong enough to glow weaker halogens or even blink (at around 1 Hz) any led lights connected to it. It does not matter whether the led is voltage or current dimmable.

The only way for even moderately solve for it is to connect a suppression capacitor in parallel with each output. Something like a 0.22µF 275V X2 .

At least then it's moderately usable. So unless you are running "dumbest" (electrically) possible lights with high enough load to just eat up the leakage current (when the dimmer is supposed to be turned off) or are willing and able to do some high-voltage tinkering.

Look elswhere! This device will not work as advertised!
