TRIPLE OUTPUT LINEAR D.C. POWER SUPPLY
The GPC-Series are triple output, 195 to 375W, linear DC power supplies. Channel 1 and 2 are fully
adjustable (model dependant) and channel 3 is fixed at 5V/3A with ripple and noise at less than
2mVrms. Overload and reverse polarity protection keep GPC-Series and its loads safe from unexpected
conditions. The GPC-3030DQ contains a temperature controlled cooling fan for thermal protection.
The GPC features continuous or dynamic internal load selection and series or parallel tracking for
application flexibility. The GPC-Series is an ideal solution for inexpensive bench-top applications
requiring low noise and multiple outputs.
