Designed for applications that require a basic DC voltage power supply, Rhino PSB series DIN rail mount single-phase and three-phase input power supplies with IP20-rated terminals feature rugged plastic or aluminum housings and output status LED indicators, as well as overload, overvoltage and thermal protection. Five new models are approved for Class I, Div. 2 hazardous locations, and one new unit is UL 1310 recognized (NEC Class 2). DIN rail mount 12, 24 and 48 VDC output, 85-264 VAC/ 120-375 VDC single-phase input voltage power supplies are available, in addition to three-phase, 320-600 VAC input versions with 24 VDC outputs from 60 to 960 watts. RHINO PSB series redundancy modules are designed to help prevent costly downtime due to power supply failure, and a new buffer module is an alternative to battery-based backup systems. The power supplies are available from AutomationDirect.
