🔌 Product Overview
The Tektronix PS503A is a dual-tracking, triple-output DC plug-in power supply module, designed specifically for TM500/TM5000 mainframe systems.
-
Dual variable outputs: 0 to +20 V and 0 to –20 V at 1 A each (when installed in high-power compartment), or 400 mA each in standard compartments
-
Fixed output: +5 V at 1 A for digital logic
-
Total power rating: ~45 W .
🔧 Key Features
-
Independent voltage and current controls for positive and negative supplies, with tracking mode for symmetrical output .
-
Continuously variable current limit from ~50 mA up to rated current, providing current‑limited and constant‑voltage modes .
-
Floating supplies for flexible grounding configurations; enhances experiment setup versatility .
-
Built‑in over‑voltage protection and optional remote programming through resistance control
The PS503A is ideal for engineers needing precise, adjustable bipolar voltage rails alongside a stable digital supply in modular test systems. Built-in protections, tracking, and flexibility make it a staple in legacy Tektronix setups.
