A stand-alone high quality laboratory power supply that comes equipped with an easy-to-read digital display for both voltage and current. Its unique feature is that the heatsink, potentiometers, and output terminals are all mounted on the PC Board so only the transformer secondary wires require external connection. The circuit incorporates a current limiter, which provides overload protection. This allows for continuous maximum current adjustment from approximately 0 to 2A. An overload indicator LED is also incorporated as well as coarse and fine voltage adjustments. Supply voltage: 24 to 26VAC / 2A and 18VAC C.T. @ 300mA. Recommended transformers: 640-242 and 640-1803.
