Lambda / TDK / EMI EMHP50-1000-D-42212

The Lambda/TDK EMHP50-1000-D-42212 is a 20 kW regulated power supply built on SCR phase control topology for high-current DC applications. It delivers 0–1000 A output current with constant voltage and constant current modes, automatic crossover control, and ±0.1% line and load regulation. Forced air cooling, built-in RFI protection, and fully programmable operation make it suitable for applications demanding raw bulk power delivery. The unit features fully metered output with mode indicator lights, contactor-based interlock control, and lifting eye-bolt provisions for installation. Three-phase AC input accepts 440–480 VAC at 50/60 Hz. Output voltage capability extends up to 600 VDC. Transient response recovers to within 1% of final value in 200 ms under ±10% line variation or 50–100% load change. Output voltage stability holds ±0.05% for 8 hours under constant external conditions. Note: This model is not recommended for new designs; Genesys™ or GENESYS+™ series are preferred alternatives.
