The TDK Lambda EMS80 is a programmable DC power supply engineered for laboratory testing, burn-in applications, and systems integration. Operating in constant voltage or constant current modes with automatic crossover, it delivers adjustable DC output with high efficiency switch-mode conversion. The series supports full analog programming and optional RSTL digital interface control, enabling seamless integration into automated test systems. Forced-air cooling maintains performance across continuous duty cycles in ambient temperatures from 0°C to 70°C, with 1% per degree C derating above 50°C.
