HVAC VFD Operations & Troubleshooting

[@HVAC559]

It's more than just being true RMS DMM. The DMM needs to have a low pass filter so it sees the RMS voltage without seeing the invidual PWM pulses.

Thanks for making these videos. I enjoy your abilities to relay information to everyone.

You could check the bridge rectifier and IGBT reverse bias diode check of the inverter board by using the 12 point checks

I use to use welding bond kits for these larger connections. Also use to do infra-red pictures to give to my customers free. Camera was not a high dollar one but would help. I educated customers about the importance to have it done on thier entire building once atleast every 5 years. Showed them how to get discounts on thier insurance by having it done

RMS =. 707 x voltage peak
Average = .637 x voltage peak
