2020年3月25日 · The family of these late 80s 100W System PSUs share the same base, the 6632A is rated at 20V 5A, the 6633A at 50V 2A and the 6634A at 100V 1A - all have different transformer and a couple of different parts. They are capable of two quadrant operation, so they can source or sink current and have programmable overcurrent and overvoltage protection on top of CV and CC mode. Operator Manual and ...

2013年6月11日 · In my newbieness I'm putting together a lab and got a HP 6632A powersupply/load from fleabay a while back. As others have noted the fans are loud. So I replaced it with THIS temperature controlled fan for $10 on newegg. Quiet now! Even when drawing full power the fan is barely audible. My lab bench is in a walkout basement utility room where the ambient temp is usually in the mid 60s F - so I ...

But does anyone know how to change or turn off the offset? I ...

2017年1月5日 · Recently I picked up an HP 6632A quite cheaply, under $75 shipped. The thing works great with the slight exception of the fan being loud. (see 1st image) Being as I plan on using this on my desk, I wanted to quiet it down but I don't want to have it over heat from throwing some low power low noise fan in that barely moves 12 CFM. After some searching around I found there are some fans with ...

2016年7月31日 · Hi all, I (sort of) recently aquired a 6632A with a broken fuseholder thinking I got myself a semi cheap PSU with one part from Digi-key (Well.. lol). In fact, only the fuse drawer was missing. Once replacing it, the problem is obvious.. the PSU is eating fuses like candy. I went through the service manual and traced the closest steps I could find to this problem but nothing looks bad in that ...

HP 6632A 20V 5A 100W - $350 I replaced all the Rifa caps, added nice Hirschmann (made in Germany) terminals on the front, added a switch to connect the sense terminals to the front connectors and added temperature control to the fan for moderate speeds during everyday use.
