  1. Please few advices... i use V130-33-T30 and PWM output. My main voltage is 24 Vdc, and i need 50% of the main voltage = 12 Vdc output for LED, just for test PWM. So i use PWM output O0 with next parameters: Frequency 50Hz(20msec), so i use MI0=8 ( 8 x base 2.5msec = 20 msec) Duty Cycle 50%, so i use MI1=500 ( 500 x base 0.1% = 50 %) Run = MB0 So when i set MB=1, i get unstable output from 10.9V to 12.8V, it is not a constant output voltage, it is very unstable. Am i doing something wrong , or ...?? Please, any advice will be very helpfull!! Thank You very much, best regards!
