Circuit DescriptionINTRODUCTION.The CPS2000 power supply provides +/-17V at 16 Amps, +8V at 1.25 Amp, and +48Vat 0.3 Amp. The main PCB (SC3804) is in

The 723 IC is powered through R11, which allows ripple filtering by C9, and voltageprotection by DZ1,2. These Zeners are not required to reduce ripple

When shutdown has ocurred, the supply is reset by turning the mains briefly off andon. R100 discharges C25 so that the circuit is ready for use at the
