Sure. If you connect nothing, set the three jumpers as required (120VAC and UNregulated Vaux), apply power and cannot get the expects VOLTS out, and have it stay ON (with no load), then Hypex needs to say how they tested it, different from you, and determine that it was fine. For instance, did they use 220VAC? If they have no explanation, and it works fine for them, but clearly not for you, they should replace it.Ok. I've looked at this and retested a couple of ten times.
What I am finding to make a long story short is I'm getting 60vDC off the high voltage pins and 12vDC off the VDR connections. Both of those seem within the correct range based off the Hypex PS datasheet p7. But they immediately fall off until reaching 0 Vdc.
The Vaux pins of both J4 and J5 are consistently measuring at 14v Dc, which does not seem correct b/c the data sheet indicates they should be 22v DC. Again the exact same issue: They exhibit this voltage for a split second when the amp is turned on and then fall rapidly to 0v DC.
Amp Standby on J5 shows 0v DC from the moment power turns on
SMPS Standby on J5also show 0v DC.
Amp enable on J4 also shows zero.
Finally, and this is the joker in the deck, DC Error on J4 flashes 14v DC when switched on before dropping to zero.
Based on the Hypex Data sheet I would not expect to read any voltage from Amp Standby, or Smps Standby because those are both input pins, so that seems normal.
However, Amp enable is an output pin and it appears to be outputting zero voltage when it should be outputting a 50v.
Finally, the DC error pin is an input pin. I am clueless why it outputs a 14v DC surge when the amp is powered up.
It does appear the behavior is consistent with the SMPS going into standby even though it isn't connected to anything. I'm inclined to pitch the thing into file 13 and order a new one.
Anyone have any ideas?
