About 1794-PS3

The Allen-Bradley 1794-PS3 is a FLEX I/O DC power supply module. It can provide up to 10 adapter modules with 24 Volts DC power. Users can also use the 1794-PS3 module to provide power to an entire FLEX I/O system. This module can convert 120 or 230 Volts AC to 24 Volts DC at 3 Amps when it is mounted horizontally or at 2.8 Amps when mounted vertically. Note that either 3 Amps or 2.8 Amps is the module's maximum output current, depending on its mounting. The entire module measures 3.7 x 2.7 x 3.4 inches. It uses an open-style enclosure and can be mounted horizontally or vertically using a DIN rail or panel mount. It requires an isolation between the DC output terminals and AC input terminals.

The nominal power supply input voltage of this module is 120 to 230 Volts AC, 47 to 63 Hertz, and 1.4 Amps (for 120 Volts AC) or 0.8 Amps (for 230 Volts AC), while its nominal output voltage is 24 Volts DC. It also has a power supply input power of 86 W, a maximum apparent input power of 205 VA, and a maximum transformer load of 250 VA. The maximum input current of this module is 1.9 Amps, minimum load is 50 mA, output power is 72 W, and output ripple is a maximum of +/-5% 1200mV peak-to-peak. The 1794-PS3 module also has a leakage current of a maximum of 0.5 mA RMS at the rated input and output and an overcurrent protection of up to 3.2 Amps. Its power dissipation is 12 W while its thermal dissipation is 41 BTU/hour.
