Lambda / TDK / EMI EMHP60-500

The Lambda/TDK EMHP60-500 is a 500W regulated power supply employing SCR phase control topology for precision DC output in demanding industrial and laboratory environments. It combines fully programmable constant voltage and constant current modes with automatic crossover, forced air cooling, and built-in RFI protection to deliver stable, metered power with mode indication and contactor interlock control.
