This unit
The TDK-Lambda EMHP30 is a high-power DC power supply employing regulated SCR phase control topology for demanding industrial and test applications. This fully metered unit delivers constant voltage and constant current operation with automatic crossover, variable-speed forced air cooling, and built-in RFI protection. The EMHP30 represents a 30V, 3000A model within a series extending to 90 kW maximum output. Though legacy equipment not recommended for new designs, it remains operational for existing installations requiring high current bulk power delivery with precise regulation and contactor-based on/off interlock control.

Key Features
Delivers up to 90 kW DC output with 3000 A maximum current capability
Dual-mode regulation eliminates manual crossover switching between CV and CC operation
Full metering and visual mode indication for operational transparency
Variable-speed cooling optimizes thermal efficiency and reduces acoustic noise
Wide AC input tolerance (440–480 VAC) accommodates utility supply variations
Typical Applications Electrolytic cell power, galvanizing systems, battery charging, materials testing, and industrial process control requiring stable, high-current DC delivery.
Compatibility & Integration Legacy TDK-Lambda equipment. For new designs, TDK-Lambda recommends Genesys™ or GENESYS+™ series alternatives.
