Description
Lambda LCS-A-15 Regulated Power Supply 15VDC 1.8A 105-132VAC Input Bench
The Lambda LCS-A-15 is a compact linear regulated DC power supply manufactured by Lambda Electronics Corp. (a Veeco Instruments subsidiary) in Melville, New York. It delivers a stable 15 VDC ±5% output from a standard 105–132 VAC, 57–63 Hz line input, with output current capacity that scales with ambient temperature. Connections are made via a labeled screw terminal block on the output face, accommodating sensing, voltage, and AC leads.

Applications
Lambda Electronics was a well-regarded US manufacturer of linear regulated power supplies from the 1960s through the 1980s, and the LCS-A series represents a classic vintage benchtop design from that era. Linear regulated supplies like the LCS-A-15 are still used today in laboratory, instrumentation, and legacy electronics applications where low-noise, tightly regulated DC voltage is needed — they produce no switching artifacts and are preferred over switching supplies for noise-sensitive circuits. The 15 VDC output is a common rail voltage for analog instrumentation, op-amp circuits, and older laboratory test equipment. The terminal-block output makes it straightforward to wire into custom test setups, instrument racks, or equipment requiring hardwired DC power. These units are commonly sought for maintaining vintage lab instruments and industrial control systems that specified a particular DC rail voltage.
This Lambda LCS-A-15 Regulated Power Supply has been inspected and is in good used condition. The chassis shows normal surface wear consistent with lab or bench use — light scuffing and handling marks on the gray painted enclosure — but no dents, cracks, or damage to the housing. The terminal block connections and wiring are intact and appear clean. The rating plate is legible. Please review our photos and contact us with any questions.
