24 V DC Switching Power Supply – ELCO K100A-24
The K100A-24 is a 24 V DC switching power supply (“DC Switching Power Supply”) manufactured by ELCO, designed to power control electronics in industrial environments and on CNC machine tools. The -24 suffix identifies the nominal regulated output voltage of 24 V DC. The unit is intended for powering I/O modules, PLCs, safety relays, encoders and electrohydraulic valves located in the machine’s electrical cabinet. Multiple hardware variants may exist; verify the revision before replacement.
The DC power supply is the heart of the logic power distribution in a CNC machine: it converts the mains voltage to stable, filtered 24 V DC, ensuring continuous supply to PLCs, I/O modules, encoders, safety relays and low-power actuators. Its failure causes immediate shutdown of all control circuits, resulting in total machine downtime; an unstable or out-of-tolerance output voltage can also generate communication errors, unexpected CNC resets and anomalous axis behaviour.
ELCO is a manufacturer specialising in industrial power supplies and power electronics components for industrial automation and machine tools. Products in the K100A series are engineered for demanding industrial environments, with particular attention to reliability under variable loads and mains disturbances. Models in this family are legacy / discontinued: available exclusively as used, surplus or through specialist repair services.
