MULTIPLE OUTPUT LINEAR D.C. POWER SUPPLY
The GPS-Series is dual to quad output, 180 to 200W, linear DC power supply. Overload/reverse polarity
protection and output On/Off switch keep GPS and loads safe from unexpected conditions. High
regulation and low ripple/noise are maintained at 0.01% and less than 1mVrms, respectively. Cooling
fan speed control minimizes fan noise according to load conditions, ensuring quiet operation. The
GPS-Series is an ideal solution for lightweight, inexpensive bench-top or portable applications
requiring high regulation and multiple outputs.
