PS503

Manuals – Specifications – Links – Pictures

The Tektronix PS503 is a triple power supply plug-in for the TM500 system.

It supplies 0 to −20 V and 0 to +20 V at 0.4 A as well as +5 V at 1 A.

The PS503A version delivers +/- 20 V at 1 A when used in TM500 high-power compartments.

The variable supplies can be adjusted independently or can track one another, and are floating; the 5 V output is ground referenced.
