Description
The Chinfa WRA120-12 is a compact three-phase DIN rail power supply designed for industrial automation, machinery and control-panel applications. It provides a regulated 12VDC output at up to 10A, delivering 120W of continuous output power.
A wide three-phase input range of 340 to 575VAC allows the WRA120-12 to operate from common industrial 400V and 480V supplies. Its compact metal enclosure and high-efficiency design make it suitable for installations where reliable 12VDC power is required from a three-phase mains source.
Integrated short-circuit, overload, overvoltage and overtemperature protection help safeguard the power supply and connected equipment. Natural convection cooling eliminates the need for a fan and supports dependable operation in industrial control cabinets.
