The EMS300-16 is a high-power switch-mode AC-to-DC power supply delivering 5000 W across a 0–300 V adjustable output range at 16 A. Built for laboratory testing and burn-in applications, this unit combines constant current/constant voltage operation with automatic crossover, analog programming, and optional RSTL digital control. Voltage and load regulation both achieve 0.1%, with transient response under 650 microseconds. Overvoltage protection and thermal safeguards are standard. The supply supports single and three-phase input, series/parallel operation with master-slave configuration, and includes soft start for system reliability. Its rack-mountable form factor and high packaging density suit integration into automated test environments and demanding electrical characterization workflows.
