The National Instruments PS-14 (Part Number: 783167-01) is a reliable 24 VDC industrial power supply designed to deliver superior performance in various automation applications. Capable of offering up to 150% short-term power capability, the PS-14 features robust output capacitors that efficiently charge capacitors, initiate motors, and absorb reverse energy. This power supply operates within a wide input voltage range of 100 to 240 VAC and is characterized by approximately 90% operating efficiency, ensuring minimal energy loss and reduced operational costs.

The device includes four output terminals—two positive and two negative—where both negative and positive terminals are internally wired for simple connection. Each terminal supports an output current of 3.3 amperes at 24 VDC, with adjustable output voltage ranging from 24 V to a maximum of 28 V, governed by an integrated potentiometer. However, it is important to adhere to the manufacturer’s recommendation of not exceeding 28 V to ensure optimal performance.

On the front panel, three input terminals for line (hot), protective ground, and neutral facilitate easy integration for both single-phase and two-phase AC input configurations. The PS-14 weighs 430 grams and has compact dimensions of 32 x 124 x 102 mm, making it efficient for installation in a variety of setups; side or panel mounting kits are available to suit different requirements. The operating temperature range is from 0 °C to 49 °C, with an operating relative humidity of 0 to 90%. The PS-14 is backed by a three-year warranty and includes a user manual and maintenance manual available for download. For pricing information, please contact a sales representative.
