I decided to replace the psu with three din supplies since it was a repeatable issue with the 5v rail. Machine is back in operation now with no signs of problems.

driving triacs in power supply

Electronics Forum | Sat Jul 24 06:00:50 EDT 2004 | zlatkon

I need to build regulated power supply 0-30V 0-20 Amps. The only solution possible for minimizing the thermal loss is to use triacs on the secondary Trafo side in order to cut the sine for low voltage output and great current. (like 5V, 20A). Please

I was able to repair the original power supply for the printer again with parts from another similar power supply on ebay. At first the machine didn't power up properly even though the supply voltages were all good on a volt meter when tested befor

We always have big power modules on the board,they are very heavy,so we use the screw to fix the soldered module,then we destroyed the solder joints.If we screw them first, the board can't be wave soldered. My questions: whether we should use the s

Got it powered back on Friday.... We did check the UPS (power-supply)and indeed it was bad. So we referenced the manual and found you can bypass the UPS all together. So we just directly plugged the machine past the UPS. Well the machine is running b

FUJI IP3 MFU1 no power

Hi there. I have an IP3 machine that refuses to power up the MFU cart on side 1. I have already replaced the I/O card but still no dice. Is there a relay or fuse that I need to check to get this to power up? The machine will not operate the camera

Our UP500 has been running great for a few months then the AC/DC 5/12/24V power supply stopped working and the PC could not communicate with the cage. The PC screen also got very noisy. We replaced the power supply with a used replacement and the ma

OK, so went to power up again today and had the same kind of issues. The 24V and 5V lights on the cage flicker dimly about every 500ms. I tried my trick of disconnecting the +24v lead to the lift table amp and it acted the same, so it didn't work th
