The National Instruments 781094-01, also known as the PS-16 Industrial Power Supply, is designed to provide reliable power in a variety of industrial applications. This power supply accommodates AC input voltages ranging from 90 to 132 VAC or 180 to 264 VAC, while DC input is not permissible. It delivers a nominal output voltage of 24 V, with a guaranteed minimum output range of 24 to 28 V and a maximum of 30 V. The output current varies based on the voltage and operating conditions, supporting up to 12 A at 24 V and temperatures below 45 °C, and maintains a nominal output power of 288 W when operating at these conditions. At 60 °C, the output current is 10 A at 24 V, 10.3 A at 28 V with 8.6 A maximum.

The PS-16 can be configured in serial, parallel, or two-phase modes. In serial configuration, the output voltage increases but should not exceed 150 VDC when several units are connected. The parallel configuration enhances system reliability, ensuring continued operation even if a single unit fails, although failure diagnosis may be complex due to the status LED remaining lit. It is recommended to implement separate input fuses for each unit, connecting them to distinct phases or circuits where feasible. In two-phase operation, appropriate protective measures such as fuses or circuit breakers for the neutral input are essential, and phase-to-phase connections are only permissible with a supply voltage not exceeding 240 V + 10%.

With dimensions of 60 x 124 x 117 mm and a weight of 700 g, the 781094-01 operates effectively within a temperature range of –25 °C to +70 °C, and can be stored in environments ranging from –40 °C to +85 °C. The recommended relative humidity for operation is between 5% and 95%, and it is suitable for altitudes up to 6000 m. This combination of features makes the PS-16 a versatile solution for industrial power supply needs, ensuring efficiency and reliability in challenging environments.
