The Ametek SGA500/50 is a 25 kW programmable DC power supply engineered for high-demand test, measurement, and production environments. Delivering 0–500 V and 0–50 A across a compact 3U chassis, this unit combines high power density with modular architecture and extensive remote control options. Its fast load transient response, low ripple and noise performance, and stackable design make it suitable for R&D, system integration, and component testing where precise voltage and current control are critical.
