Pan Command Power Supply Ps-6 Serial No: 0379. Condition is Used. Dispatched with Royal Mail 2nd Class.

Product Description

The PS-6 power supply offers a low-voltage bipolar output (up to +/-50Vdc), suitable for solid-state power amplifier or OpAmps; in addition, the PS-6 power supply holds a voltage quintupler that yields a single high-voltage B+ output voltage roughly equal to five times the rail voltage. For example, if the rail voltages are +/-30V, the high-voltage B+ output voltage will be about 147Vdc; if the rail voltages are +/-15V, the high-voltage B+ output voltage will be about 73Vdc.

A quick overview. A low-voltage, center-tapped secondary is required, from 10V-0V-10V to 30V-0V-30V. The PS-6 power supply's voltage quintupler uses a full-wave rectification to establish the high-voltage B+ voltage, which explains why there are so many power supply capacitors.

The two low-voltage rail voltages are determined by the secondary voltage against the square root of 2 (1.414), minus the rectifier voltage drop (0.6V to 0.8V). For example, given two 22Vac windings (44Vac CT) and 0.7V rectifier drop, we can expect (22Vac x 1.414) – 0.7vdc volts, or 31Vdc, for each rail. With this 22V-0-22V secondary, a high-voltage B+ of about 147Vdc will also be established.
