The Rockseed RS305P programmable power supply is a single-output high-precision DC supply, microprocessor controlled with LED display of voltage, current and power at the same time.
Every electronics workbench should have at least a couple of power supplies available especially when testing out equipment. My radio equipment is run from a 50amp power supply, and I have a second 45amp supply for bench testing. I also use a Rockseed RS305P bench supply when working on equipment or projects where I need to limit either the voltage or current.
