Tektronix PS503 Triple power supply plug-in

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 later 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
