The EHA Power Supplies are DIN-rail-mounted electronic power modules intended for installation in control cabinets as part of hydraulic control systems.
The series operates from a nominal 24 V DC input and is used to provide auxiliary supply voltages for compatible proportional valve and amplifier applications. These modules are designed to snap onto DIN EN 50022 or DIN EN 50035 rails, use screw-clamp terminals for wiring, and place status indication and user-accessible elements on the front of the unit. The housing is made of polyamide 6.6 and carries an IP20 protection rating, with an operating temperature range of 0 to 50 °C and a storage range of -25 to 85 °C. The series also meets the listed vibration and EMC requirements, including IEC 68-2-6 environmental criteria and EN 50081-2 / EN 50082-2 electromagnetic compatibility standards.
