The TDK-Lambda GENH 30-25 is a 750 W programmable DC power supply offering 0–30 Vdc output with 0–25 A capability. Designed for industrial test, development, and production environments, this 1U rackmount unit combines precise voltage and current control with active power factor correction (0.99) and 85% typical efficiency across a 85–265 Vac single-phase input range (47–63 Hz). The supply operates in both constant voltage and constant current modes with automatic switching, delivering exceptionally low voltage ripple noise (0.008 Vrms, 5 Hz to 1 MHz) and current ripple noise (0.063 Arms, 5 Hz to 1 MHz) for sensitive applications.
