The Lambda/TDK GEN 20-120 is a 2400 W programmable DC power supply designed for OEM, industrial, and laboratory applications. It delivers 0–20 Vdc at 0–120 A with 87% typical efficiency and ultra-low output ripple noise of 0.008 Vrms across 5 Hz–1 MHz. The unit accepts single-phase AC input from 170–265 Vac (47–63 Hz) with active power factor correction at 0.99 full-load rating, eliminating dependency on narrow mains windows.
## Technical Specifications
