2 and 3-phase operation Features Input voltage range: 320 575VAC Output trim range: 22.5 29.5VDC AC/DC Converter High electrical strength high reliability DIN-Rail Permanent overload and short-circuit protection Parallel operation capability Series REDIN960/3AC International safety certification listing Description 960 Watt The REDIN/3AC is a series of rugged DIN rail power supplies for two and three-phase mains 3 Phase operation from 320 to 575VAC without the need of a neutral connection. Four versions with a maximum current limited output deliver 5A, 10A, 20A or 40A without derating up to +55C. The output DIN-Rail can be grounded via a third common output terminal. The LED signal on the front panel indicates that the output voltage remains within the wide adjustable range from 22.5 to 29.5VDC. The units are covered by international safety certificates and are intended for worldwide use. In power-hungry applications, the Power Supply units can be connected in parallel with no need for additional components. Selection Guide (1) Part nom.
