Lambda / TDK / EMI EMHP50

The EMHP50 is a high-power DC power supply engineered for demanding industrial and research applications requiring regulated bulk power delivery. Built on regulated SCR phase control topology, it delivers fully programmable constant voltage and constant current output with automatic crossover functionality. The unIt has exceptional line and load regulation of ±0.1% within rated limits, with output stability maintained to ±0.05% over 8-hour periods. Transient response recovers to within 1% of final value in 200 ms following line variations of ±10% or load swings between 50% and 100% of rating.
