National Instruments 783167-01 DC Power Supply

Part Number 783167-01 is the identifying part number for the National Instruments PS-14 DC Power Supply. The power supply comes equipped with a set of features that makes it ideal for powering motors, charging capacitors, and absorbing reverse energy. Some of these features are small size, a wide input range of 100 to 240 V, high efficiency (up to 89.8%), 150% peak load capability, DC input range of 110 to 300 VDC, and active power factor correction.

The 783167-01 has a nominal AC input voltage range of 100 to 240 VAC while it can sustain a minimum of 264 to 300 VAC for less than 500 ms. The nominal input frequency is 50 to 60 Hz (±6%). Likewise, the typical input current is 1.5 A at 100 VAC, 1.24 A at 120 VAC, and 0.68 A at 230 VAC given that it is outputting 24 V, 3.3 A. On the other hand, the 783167-01 typically supports DC inputs from 110 to 375 VDC for continuous operation. The DC input current can be 0.81 A at 110 VDC or 0.29 A at 300 V, given that the output is 24 V, 3.3 A.  

The 783167-01 has a typical output voltage range of 24 V to 28 V, which can reach a maximum of 30 V.  The nominal output current is 3.3 A at 24 V and 2.7 A at 28 V. Likewise, the nominal output power is 80 W. This module is recommended for operation in temperatures from -25 °C to 70 °C. On the other hand, it can be stored in temperatures from -40 to +85 °C. Note that the relative humidity must be between 5% to 95%. Furthermore, the power supply can be operated up to altitudes of 6000 m. 

The 783167-01 employs several protection features. First, the output is electronically protected against overload, no-load, and short-circuits. Likewise, there is an output overvoltage protection for a maximum of 39 VDC. In addition, it also features an electronically limited output over-current protection, penetration protection, and over-temperature protection.
