DC Switching Power Supply – COSEL LDC15F-2
The LDC15F-2 is a DC switching power supply (“DC Switching Power Supply”) manufactured by COSEL, belonging to the LDC series of compact low-power industrial converters. Documented as a logic supply component in CNC control systems and industrial panels, it delivers a regulated DC output voltage — in the F2 variant typically +12 V DC — with a nominal output power of approximately 15 W. The unit accepts wide-range universal AC input and includes built-in overload and short-circuit protection.
The LDC15F-2 power supply provides stable, filtered logic supply voltages to the machine’s CNC control circuits: CPU boards, I/O modules, encoders, and communication interfaces all depend on clean, stable voltage to operate correctly. A failure or excessive ripple causes random CNC errors, parameter loss, unexpected shutdowns, or irreversible damage to control boards.
COSEL Co., Ltd. is a Japanese manufacturer founded in 1969, headquartered in Toyama, specialising in high-reliability switching power supplies for industrial, medical, and CNC applications. COSEL products are globally recognised for their long operational life and low electromagnetic interference. Some legacy series such as the LDC are legacy / discontinued: available primarily as NOS (new old stock), used, or through specialist repair.
