Kerry D. Wong did teardown on a single-channel Amrel PPS 35-2 programmable power supply:
A while back, I did a teardown on a dual-channel Amrel PPS-2322 programmable power supply, and was quite impressed by its solid construction. Recently, I found another Amrel power supply on eBay and this time it is a single channel version (PPS 35-2). Let’s take a look inside this signal channel version and see how much in common it has compared to the dual channel 2322.
The single channel version of the Amrel programmable power supply has front panel sensing terminals making it handy for remote sensing applications. Although the dual channel version has remote sensing capability as well it is only available through wiring at the rear terminal block so it is less convenient.
