Three-Phase Power Supply

An industrial three-phase power supply outputs 20 A. The supply features an input range suitable for North American and European machine-tool, material-handling, and automotive industries. Standard DIN-rail-mount, three-phase designs provide 24 Vdc directly from power feeds, which can eliminate large stepdown transformers. Standard electrical features include input power-factor-correction circuit and electronic-overload and short-circuit protection with U/I characteristic. The power supply weighs 5 lb and takes up 9 in. of space.
