The TDK-Lambda ZUP6-66 is a single-output programmable DC power supply delivering 396 W across a 0–6 VDC, 0–66 A output range. Engineered for laboratory and industrial environments, this 3U rack-mount unit operates from 85–265 VAC, 47–63 Hz input and combines constant voltage and constant current modes with multi-level protection: overvoltage, undervoltage, and foldback circuits. Load and line regulation reach 2 mV + 0.005% for voltage and 0.01% + 5 mA for current, while voltage ripple noise stays below 0.005 Vrms across 5 Hz to 1 MHz.
Technical Specifications
Output voltage spans 0–6 VDC with ±0.005% load and line regulation plus 2 mV offset. Output current reaches 0–66 A with ±0.01% load/line regulation plus 5 mA/2 mA offset respectively. Typical efficiency is 77%. Voltage and current ripple noise measure 0.005 Vrms and 0.1 Arms across the 5 Hz to 1 MHz band. Integrated ammeter and voltmeter accuracy: 0.02% + 5 mV. Operating temperature range: 0–50°C. Unit weighs 3.2 kg and measures 70 mm (W) × 124 mm (H) × 350 mm (D).
