The Nemic-Lambda LWT50H-5FF is a 50 W open-frame AC/DC power supply with three outputs: +5 V at 8.0 A, +15 V at 1.5 A and -15 V at 1.0 A. It belongs to the Lambda LW series of low-profile triple-output supplies, now listed by distributors under TDK-Lambda. The board inside is marked DENSEI-LAMBDA SCB103C. This unit came out of a SELA EM2 sample preparation system.
What does the label say?
LWT50H-5FF, input 100-240 VAC ~1.5 A, 50/60 Hz, output +5 V 8.0 A, +15 V 1.5 A, -15 V 1.0 A, 50 W max, CE and cURus marks, Nemic-Lambda, made in China. A second label on the bottom cover reads LWT50H-5FF HFP with code 426-622CDT-0230W5105.
What is a triple output power supply?
It gives three separate DC voltages from one AC input. On the LWT50H-5FF, +5 V is the main output (output 1) and +15 V and -15 V are outputs 2 and 3. Per the LW series datasheet, outputs 2 and 3 are isolated from output 1. The total load must stay within 50 W.
What is an open frame power supply?
An open-frame supply is a bare board on a metal chassis, without a full enclosure, made to be mounted inside equipment. The LW series is 26 mm high and is cooled by natural convection.
What is in the photos?
The board from above with its input and output wire harnesses, the rating label, close-ups of the SCB103C board marking and the fuse warning, and the bottom cover label. Condition: used.
