The Lambda/TDK/EMI GEN 80-42 is a programmable DC power supply delivering 3360 W across 0–80 Vdc and 0–42 A. Built on TDK-Lambda’s power electronics foundation, this unit combines active power factor correction with integrated EMI filtering to ensure stable, clean output in industrial, laboratory, and OEM environments. Output voltage ripple is held to 0.025 Vrms across 5 Hz to 1 MHz, with current ripple at 0.08 Arms in the same band. Efficiency reaches 88% typical, scaling to 90.5% in the G+ variant.
