National Instruments PS-17

The National Instruments PS-17 Industrial Power Supply, designated by part number 781095-01, is engineered to deliver a robust output power of 480 Watts, with an output current capacity of 20 Amperes and an adjustable output voltage range of 24 V to 28 VDC. It operates efficiently within an input voltage range of 85 to 276 VAC or 110 to 150 VDC, ensuring compatibility with a variety of power sources. This power supply excels in handling dynamic loads, offering up to 150% peak load capability and incorporating active power factor correction for enhanced efficiency. The PS-17 is equipped with spring-clamp terminals for easy, tool-free field installation, along with a DC OK relay contact that continuously monitors output voltage. This crucial feature ensures that the contacts close when the output voltage meets the set point and opens in the event of a dip exceeding 10% below the set point, resetting automatically when voltage recovery occurs. Additionally, the power supply includes an output voltage potentiometer, allowing for precise voltage adjustments within the specified range. Designed for operation in conjunction with multiple units while maintaining a net output voltage below 150 VDC, the PS-17 must be used with power supplies of the same type to ensure compatibility. With dimensions of 82 x 124 x 127 mm and a weight of 1200 g, it operates effectively in a temperature range of -25 °C to 70 °C and has a storage temperature capability of -40 to 85 °C under non-condensing relative humidity conditions of 5% to 95%. The PS-17 adheres to strict electrical safety standards, complying with IEC/EN 60950-1 and UL 508.
