This unit

The Lambda/TDK LPD421A-FM is a dual-output, adjustable regulated DC power supply engineered for laboratory, educational, and industrial applications. Each independent channel delivers 0–20V DC at 0–1.7A, with a maximum power output of 68W per channel. Exceptionally low ripple (500 µVrms) and tight line/load regulation (≤0.01% + 1mV) ensure stable power for precision testing, circuit development, prototyping, and repair work.


Both outputs can operate independently or be configured in series for doubled voltage or parallel for doubled current (3.4A maximum). Comprehensive front-panel meters monitor voltage and current simultaneously for each channel, while coarse and fine adjustment controls provide precise output tuning. Built-in overload protection, automatic current limiting, and thermostat-based thermal shutdown safeguard equipment and circuits.


Convection cooling eliminates external heat sinks.
