Lambda / TDK / EMI EMHP80-250-D-42111

The Lambda/TDK EMHP80-250-D-42111 is a three-phase DC power supply with integrated EMI filtering, engineered for high-power industrial and laboratory applications. This 20 kW unit delivers 0–80 VDC at 0–250 ADC with constant voltage/constant current regulation and automatic crossover. Built-in RFI protection, forced air cooling, and floor-mounting flexibility make it suitable for electromagnetics, cryogenic magnets, battery charging, precision electroplating, plasma power, and industrial DC power systems.
