The Lambda/TDK EMI EMS40 is an enclosed switch-mode DC power supply engineered for industrial, embedded systems, laboratory test, and burn-in applications. It delivers well-regulated, adjustable DC voltage or current with constant voltage/constant current operation and automatic crossover. Universal AC input acceptance (50/60 Hz) and active power factor correction on select models ensure flexible deployment across global power infrastructures. Built-in overvoltage, overcurrent, and thermal protection safeguard loads in demanding environments. Efficiency reaches 88% or higher. Full programmability via analog or optional RSTL digital interface supports both local and remote control.
