The EMHP40-1500 power supply provides 0 to 40 vdc at currents up to 1500 A (60 kW). Based on a regulated SCR phase control topology the EMHP series is ideally suited to applications where raw bulk power is required in a robust reliable package. All models are fully programmable sources of constant voltage and or constant current with automatic crossover and fully metered. In an SCR phase-controlled DC Power Supply, output is controlled by modulating the conduction angle of the controlling SCRs.
