The Lambda/TDK EMI ESS60-165-7-D is a programmable DC power supply delivering 10 kW to 15 kW of regulated power in a 5U rack-mount form factor. It operates in both constant voltage and constant current modes with pulse-by-pulse current limiting, making it suitable for high-current applications including RF amplifiers, DC motors, and magnetic coils. The unit features integral cooling, analog front-panel control via ten-turn potentiometers, and optional remote programming through RS232/IEEE 488 interfaces. Line and load regulation both hold better than 0.1% across full load changes. Output stability maintains ±0.05% deviation over 8-hour periods under constant operating conditions.
