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, and was introduced in 1972.

The PS503A version (introduced in 1976) 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.

Key Specifications

Output voltage 0 to +20 V and 0 to −20 V, floating; 5 V ±5%, ground referenced
Current limit <100 mA to >1 A variable (0.4 A for original PS503 or if used in low power compartment); 1 A fixed on +5 V
Ripple and noise <3 mVp-p @ 1 A on either rail

Rear interface connections

  • +20 V output (22A)
  • −20 V output (22B)
  • ±20 V common (24A, 24B)

(connections below require various jumper changes in the PS503 as described in the manual)

  • Remote resistor or voltage programming (via 25A, 25B) or
  • Remote sensing (+ Sense 23A, − Sense 23B)
