The TDK-Lambda EMS200-25-2-D is a 200W DC power supply engineered for laboratory test and burn-in applications. It delivers stable, adjustable DC voltage and current with constant voltage (CV) and constant current (CC) modes featuring automatic crossover. Built-in protection circuits, including overvoltage, overcurrent, and overtemperature safeguards, ensure reliable operation across demanding test environments. The unit accepts single-phase AC input from 85–265 VAC (47–63 Hz) and reaches up to 89% efficiency. Front-panel voltage and current adjustment knobs enable local control, while remote programming via analog resistance, external DC voltage, or external DC current supports automated test sequences. Standard interfaces accommodate integration with external equipment and test systems.
