EHA Power Supplies

EHA Power Supplies are electronic power modules designed for DIN-rail installation inside control cabinets used in hydraulic control systems. Operating from a nominal 24 V DC input, they provide auxiliary supply voltages for compatible proportional valve and amplifier applications. Each unit clips onto DIN EN 50022 or DIN EN 50035 rails and uses screw-clamp terminals to simplify wiring. Status indicators and user-accessible controls are arranged on the front panel for straightforward operation and monitoring. The enclosure is manufactured from polyamide 6.6 and carries an IP20 rating. Specified temperature ranges are 0 to 50 °C in operation and -25 to 85 °C in storage. The series also complies with defined vibration and electromagnetic compatibility requirements, meeting IEC 68-2-6 environmental test criteria as well as EN 50081-2 and EN 50082-2 EMC standards.
