Allen-Bradley 1606-XLS960F-3 NSNBC01 Power Supply

Allen-Bradley 1606-XLS960F-3 NSNBC01 Power Supply is a 960‑W switched‑mode power supply that converts 380–480 V three‑phase AC input to a tightly regulated 48–54 V DC output at up to 20 A, making it suitable for demanding industrial control applications that require a robust 48 V DC rail. This unit is part of the 1606 XLS Performance family and supports rail‑mount or wall mounting, with a compact enclosure rated IP20 and a footprint of 110 mm wide by 124 mm high by 127 mm deep, weighing about 1.5 kg. Key electrical characteristics include an output of 20 A at 48 V DC (approximately 17.7 A at 54 V DC), hold‑up time around 20 ms, an input current around 1.65 A and inrush current ~4.5 A, a power factor of ~0.88, and typical efficiency near 95% with a maximum ripple of 150 mV. The supply supports parallel operation for higher availability and offers a reserve capability of about 30 A at 48 V DC to handle transient loads; it also carries Class 1, Div 2, ABS/GL/RINA (marine) certifications as applicable. External input fusing recommendations include a minimum 6 A fuse, and the product is designed for reliable operation with MTBF around 375,000 hours at 40 °C. All told, the 1606-XLS960F‑3 NSNBC01 provides a high‑density, industrial‑grade 48–54 V DC power source with solid efficiency, protection, and mounting versatility for rugged environments.
