Lambda / TDK / EMI GEN 40-19

The TDK-Lambda GEN40-19 is a programmable DC power supply delivering 40 V at 19 A (760 W) for industrial, OEM, and laboratory applications. This single-channel Genesys™ series unit operates from 85–265 VAC single-phase input and provides constant-voltage/constant-current (CVCC) conversion with 87% typical efficiency. Voltage ripple and noise measure 0.008 Vrms; current ripple and noise measure 0.048 Arms (both 5 Hz to 1 MHz). Line and load regulation achieve ≤0.01% of output plus 2 mV or 2 mA respectively. Programming accuracy is ±0.1% for voltage and ±0.2% for current. The supply includes over-voltage, over-current, and over-temperature protection with foldback control. Output voltage and current are independently adjustable from 0–40 V and 0–19 A. Hold-up time exceeds 20 ms at 100 VAC with full load; inrush current remains below 25 A.
