The TDK-Lambda / Nemic-Lambda GEN 40-38-IEMD is a 1520 W programmable DC power supply engineered for OEM, industrial, and laboratory applications requiring high power density and flexible control. Operating from 0 to 40 Vdc and 0 to 38 A with 88% typical efficiency, this unit delivers clean power with 0.008 Vrms voltage ripple and 0.095 Arms current ripple across the 5 Hz to 1 MHz bandwidth. The supply accepts a wide AC input range of 85 to 265 Vac (47 to 63 Hz, single-phase) and features active power factor correction at 0.99 typical at full load. Built on modular and SMT technology, the GEN 40-38-IEMD integrates CV/CC auto-crossover control with extensive digital and analog interfaces, enabling standalone operation or integration into multi-unit systems via active current sharing or daisy-chain addressing.
