The Lambda/TDK/EMI ESS60-165 is a 15 kW programmable DC power supply delivering 0–60 VDC at 0–165 ADC for high-current industrial and laboratory applications. It combines constant voltage and constant current operation with automatic crossover, pulse-by-pulse current limiting, and front-panel adjustment via 10-turn potentiometers or optional RS232/IEEE 488 interfaces. Output stability is exceptional: line regulation better than 0.1%, load regulation under 0.1%, and 8-hour drift under 0.05% at constant conditions.
