The Rohde & Schwarz NGT Triple Power Supply is a precision instrument delivering three independent, galvanically isolated outputs for simultaneous multi-circuit testing in R&D and production environments. It operates as a constant-voltage source with current limiting, or as a constant-current source for less demanding applications. Channels support independent, series, and parallel operation, with tracking capability between outputs A and B. The NGT3600 series delivers up to 80 V and 50 A per channel, with 1 mV voltage and 1 mA current programming resolution. Voltage readback achieves 1 mV resolution; current readback reaches 100 µA to 1 mA. Integrated meters provide high-resolution real-time monitoring across the full output range. Voltage ripple and noise measure < 5 mV (RMS) from 20 Hz to 20 MHz at 30 V/25 A. The NGT3621 delivers 1800 W total output power; the NGT3622 provides 3600 W. Multi-layer protection includes overvoltage protection on the 6 V channel C (adjustable 4.5 V to 10 V threshold), overcurrent, overtemperature, over-power protection, and safety limits. A high-resolution display enables intuitive operation and parameter adjustment.
