The Lambda/TDK GEN 400-37.5 is a 15 kW programmable DC power supply built on the Genesys™ platform for industrial test, development, and production environments. This 3U rackmount unit delivers 0–400 VDC at 0–37.5 ADC with exceptional voltage ripple (0.06 Vrms) and current ripple (0.01 Arms) across the 5 Hz to 1 MHz band. Input accepts three-phase AC at 47–63 Hz, with selectable voltage configurations (180–253 VAC for 3P208; 432–528 VAC for 3P480). Efficiency reaches 88% minimum at low AC line and 100% rated load.
## Technical Specifications
• Output: 0–400 VDC, 0–37.5 ADC (15 kW rated)
• Input: Three-phase AC, 47–63 Hz; 3P208 (180–253 VAC), 3P480 (432–528 VAC)
• Ripple & Noise: 0.06 Vrms voltage; 0.01 Arms current (5 Hz–1 MHz)

## Key Features
• Manual voltage and current adjustment via front-panel encoders (COARSE and FINE modes)
• OVP, UVL, and address settings adjustable through continuous encoders
• Digital and analog remote control interfaces
• Dual LED displays: voltage/OVP/UVL/address on one; current/baud rate on second
• Status indicators: Alarm, Fine Control, Preview, Foldback Mode, Remote, Output On
• RS-232 interface standard
