The TDK-Lambda GENH 300-2.5 is a 750 W programmable AC-DC power supply from the Genesys™ series, engineered for OEM, industrial, and laboratory applications requiring precise DC output control. This 1U rack-mount unit delivers 0–300 Vdc at 0–2.5 A with exceptional voltage stability: 0.025 Vrms ripple and 87% typical efficiency. Universal single-phase input (85–265 VAC, 47–63 Hz) with active power factor correction (0.99 typical at full load) ensures global deployment capability.
