The National Instruments PS-1 is a high-performance DC power supply designed for Compact FieldPoint systems, delivering a stable output of 20 VDC at 0.8 A, with a total power rating of 16 watts. Engineered to operate with a standard input of 120 VAC at 60 Hz, the PS-1 provides reliable power distribution to support up to eight I/O modules through effective regulation and filtration. It features integrated regulators that offer full fold-back protection against direct shorts and output overloads, ensuring safe operation by automatically restoring power only after the abnormal conditions are resolved. Constructed within a high-impact plastic enclosure that meets UL 94V0 standards, the PS-1 is available in a convenient plug-in, wall-mount configuration with multiple output options including cable, terminal, and modular jacks. The power supply is designed to operate efficiently in a broad temperature range from -40°C to +60°C, eliminating the need for additional cooling fans and featuring integrated power factor correction to minimize input current. Furthermore, the PS-1 is built to handle high inrush currents without instability in output voltage, supplemented by robust protections against overvoltage and overcurrent. Installation and configuration are straightforward, making the PS-1 an ideal solution for diverse industrial applications.
