Product Description:

The EHA-PSU-704-A-10 is an industrial power supply module developed by Vickers as part of the EHA Power Supplies series. Designed for cabinet mounting, the unit converts alternating mains energy into a regulated low-voltage output required by controllers, proportional valves, and sensing hardware in automated machinery. By maintaining stable direct current, it allows downstream electronics to operate independently of normal line fluctuations. This arrangement also supports standardized low-voltage distribution in hydraulic and motion-control installations where control devices must remain consistently energized.

The supply tolerates a wide nominal input of 115/230 V AC (±5%), so it can be connected to either common low-voltage branch circuit without a tap change. Its input circuitry synchronizes to 50/60 Hz utility grids, which allows operation on standard regional power systems without external frequency conversion. Internally, the stage rectifies and filters the line, delivering a regulated output of 24 V DC for PLC I/O, sensors, and related control hardware. Under continuous duty, it can source 10 A of load current, which supports several connected devices from one supply module. Residual switching noise remains below < 5% peak-to-peak, helping reduce signal disturbance in nearby analog circuits and minimizing electrical noise inside the enclosure.

A front-panel cartridge fuse rated 20 AT provides primary overcurrent protection, so an input-side fault can be isolated at the module. With a mass of 5.5 kg, the assembly can be installed on DIN rails or shelves without additional structural bracing in typical control cabinets. The weight also gives the housing a solid mounted feel in equipment exposed to routine machine vibration. Its panel-ready form makes placement near control hardware practical, which helps keep internal wiring runs orderly and easier to route inside compact enclosures.
