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 1 A (0.4 A in low power compartments) as well as +5 V at 1 A.

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