Automation Direct PSB24-480-3 AC-DC Power Supply

The Automation Direct Rhino PSB24-480-3 is a DIN-rail mounted switching power supply that converts a 3-phase, 400–500 VAC input to a regulated 24 VDC output rated up to 20 A (480 W), making it suitable for panel power distribution in automation systems. Its electrical data sheet specifies a nominal input of 3 × 400–500 VAC with a voltage range of 320–575 VAC (DC input 450–800 VDC) and a line frequency of 47–63 Hz, while the DC output is 24 VDC ± 2% (22–28 VDC) with a maximum current of 20 A. Safety and reliability features include a non-replaceable internal fuse of 3.15 A / 500 V and leakage current under 3.5 mA, plus derating of 2.5% per °C above 50 °C to preserve output under hot panel conditions. This PSB24-480-3 provides 480 W of continuous output, and is designed for use in industrial control panels and automation cabinets where a robust 24 V supply is required from a 3-phase mains source.
