Two–phase input power suppliesA line of 2-phase input, DIN rail mounted power supplies is a CSW series designed to operate using only two legs of a 3-phase circuit, thereby saving space, cabling, and circuit protection costs. The CSW series has a universal input of 185-550 Vac in single and 2-phase. This provides the same output power as a 3-phase input power supply, but at a lower cost and taking less space on the DIN rail. High efficiency and low heat dissipation as well as full electronic protection are important performance features. The CSW series 24 Vdc power supplies are available in 5 and 10 amps, 12-15 Vdc adjustable versions and 7-8 amp and 15-16 amp, and a 48 Vdc model in 5 amp, all with a universal input range of 185-550 Vac. One of the key features of this family of 2-phase power supplies is the user selectable output protection. The user can easily select hiccup or constant power protection based on the application. Also, all power supplies have both output overload and short circuit protection and are housed in fully enclosed, touch-safe enclosures.
