Hi All,
I ran into a big issue tonight and I can't seem to figure out why or if it's related to the Vipers.
Two of my Antek power supply's sparked up and blew out. I wired my Antek torroidal power supplies per the instructions for 220V and when I triggered my relay contacter to start them the solder near the bridge of one melted off and smoked up. Sparks flew. Not fun.
So, I re-checked all my wiring, turned a different power supply on without the Viper and re-checked the voltage output with my meter, it was at 140VDC which is correct. All seemed good so I plugged a different Viper (different axis) in and turned the power back on and everything seemd to test out great at first. I then turned the power supply off and turned it back on again and the power supply smoked up and the solder near the bridge melted off AGAIN!
So that's 2 out of 3 power supply's that are damaged now.
I attached some photos. On the Antek PS's I was told the the two middle wires get tied together and the outside wires go to the two hots from the power source. The larkens are wired per the instructions and the polarity was double checked on the power input.
I set the larken in 'test' mode without the jumpers and turned the current limit to halfway.
I even checked the all the servo armature wires with a 24V power supply and they all worked fine, no cross wiring.
Could it possibly be a weak board design on the Antek's? Take in mind these smoked up before I even had the axis running.
I also had the PS's wired at 110V at one point and they worked without any issues. So all the problems I've had are since wiring them for 220V.
Any help would be appreciated. I'm stuck on this one. :tired:
