The Lambda/TDK EMI LP-412A-FM is a single-output DC power supply engineered for bench and rack deployment. This convection-cooled unit delivers 0–40 V and 0–1 A with continuously variable output, dual coarse and fine voltage adjustment controls, and independent current adjustment. Built-in DC voltmeter and ammeter provide real-time monitoring of output conditions. The supply operates in constant voltage/constant current mode with automatic crossover, backed by adjustable electronic current limiting (settable to 105% of rated current) and fuse-based internal protection. Remote sensing capability compensates for voltage drop across output leads, maintaining DC regulation to better than 0.2% or 5 mA, whichever is greater. Tan, glass-filled flame-retardant nylon panels house five-way binding post connectors on the front and a covered terminal block on the rear. Operating continuously from 0°C to +60°C, the LP-412A-FM accepts 105–132 VAC input (47–440 Hz, ratings based on 57–63 Hz) and weighs 7 lbs.
