The Allen-Bradley 1794-PS3 is a Power Supply module. This module is part of the Flex I/O product family of distributed I/O modules. This module is mainly used to provide power to a Flex I/O assembly, providing the necessary backplane power to operate the installed modules.


The 1794-PS3 operates at a supply voltage range of 85-264VAC, 47-63Hz while the nominal supply voltage are 120V AC, 50/60 Hz; 1.7 A max. and 230V AC, 50/60 Hz; 1.1 A max. It requires a maximum input current of 1.9 Ampere and able to withstand an inrush current of 40 A typical, 1 AC cycle @ Vin 265V AC, 55 °C. This module also features a power supply hold-up time where Output will stay within specification when input drops out for 1/2 cycle @ 47 Hz, 85V AC with max. load.


The 1794-PS3 provides a nominal output voltage of 24VDC with voltage range of 20.4…27.6V DC, including noise and 5% AC ripple. When installed in horizontal orientation, the output current is 3 Amperes while 2.8 Amperes for other mounting orientations. It has an output power of 72 Watts and output ripple of 1200 mV peak-to-peak.


The output of the 1794-PS3 is capable of energizing up to Ten (1) Flex I/O adapters. It has an overcurrent protection of 3.2 Amperes, thermal dissipation of 41.0 BTU/hr and maximum power dissipation of 12 Watts. This power supply has an operating temperature of 0 °C < Ta < +55 °C (+32 °F < Ta < +131 °F), operating shock of 30 g and operating vibration of 5g @ 10…500 Hz.
