The TDK-Lambda GEN8-90 is a 720 W programmable DC power supply engineered for industrial, laboratory, and OEM applications requiring stable, efficient output at low voltage and high current. Operating from single-phase AC input (85–265 Vac, 47–63 Hz), this unit delivers 0–8 Vdc at up to 90 A with constant voltage/constant current auto-crossover and comprehensive protection. The compact 1U form factor accommodates both rack-mount and benchtop deployment.
