I have to design a power supply which converts 220V AC into 5V smothed DC. It has to be very small, so it shouldn't have a big transformer. Has somebody a scheme of a circuit? Thanks

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

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

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.

Hi all, I'm working on a power distribution project and decided to use the BTS50055-1TMC (this one: https://www.kasuo.com/product/bts50055-1tmc-datasheet-price-pdf/ ). It's a one-channel high-side smart power switch rated for loads up to around 70 A

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

Something on the 5v side is pulling it down. I would check every thing associated with the harness you are disconnecting. Your shorting somewhere! Don't have a schematic in front of me. Also look for leads getting into the backside of your connecto

There are pots on the board in the power supply to adjust the voltages after the machine is powered up. The location of these pots are in the munual supplied with the machine
