V3 Universal Power Supply Circuit Board

[Uunderhill]

Earlier in this thread I successfully tested my V3 board with a 12v transformer using 10k 1 watt resistors as a load. I would like to test the unit now that I have connected the recommended toroid to the PSU. The transformer is a 625VA model with dual 45v secondaries.
Will the same resistors be appropriate for testing, or will I need a more rugged option?

Review , with 45 Vac secondaries , voltage rails should be + 62 Vdc and - 62 Vdc

You've set R9 and R10 = 22 K , 3 Watts

The LED resistors R20 and R21 = 10 K , 1 Watt

P = V^2 / R = ( 62 Vdc ) ^ 2 / 10 K = 0.38 Watts

So Load resistors of 10 K , 1 watt are fine .

... recall , it takes 5 x Tau to discharge those massive caps ( see post #578 )

So keep these load resistors in because the caps will discharge faster

This is now a lethal voltage , so wear rubber gloves when taking a measurement .
