- Hi! I have a sealed power supply that I need to test for voltage and
- amperage under load and this is my problem, how do I create a 2 amp load?
- The power supply uses 120VAC 0.40A grounded and outputs (supposedly) 20V,
- 2.0A, 40VA Class 2 with four pins ( I have no idea what pins do what yet). I
- understand that if I place my meter in series between the load and the
- power supply, I should be able to read 20V (dc right?) and 2.0 amps. But
- what does the 40va mean? 40VAC? I guess what this comes down to is, how
- should I test this thing to make sure it is giving me what it should?
-
- Thanks for any help and sorry for wandering ;-).
