【英文介绍】

The Allen-Bradley 1794-PS13 is a power module in the PowerFlex I/O product family. The surge of this power supply is sufficient to power up to four (4) adapters. It has a voltage input range of 85-264VAC, 47-63 Hz, and offers a nominal output voltage of 24VDC.

1794-PS13 supports the installation method of the entire PowerFlex I/O system. It supports a Daisy chain of power output, powering supported adapters, and can also be used in combination with AC and DC modules. The power supply has a built-in indicator light that turns green when the output voltage is greater than 20.4V DC but less than 28V DC, and remains off when the power supply is not powered on and the output voltage tage exceeds 35V DC. tage protects the shutdown device and the output current is greater than 1.4A.

The 1794-PS13 has physical dimensions of 87 (H) x 69 (W) x 69 (D) mm 3.4 (H) x 2.7 (W) x 2.7 (D) inches. It has an open housing and requires a wire size of 0.34-2.5 mm2 (22-12 AWG) solid or stranded copper wire with an insulation rating of 75 °C (167 °F) or higher and a maximum insulation thickness of 1.2 mm (3/64 inch). The module is wired in class 2 and requires 0.8 Nm (7 lbs-in.) torque to tighten the connection.

The 1794-PS13 has an output voltage range of 20.4-27.6 VDC, including noise and 5% AC ripple. It has an output current of 1.3A, an output power of 31.2W, and an output ripple peak of 1200 mV.

The 1794-PS13 module's overvoltage protection is internally limited to 40 volts DC. The 1794-PS13 has a power indicator that turns green when it is turned on, and the output voltage is greater than 20.4 VDC but less than 28 VDC. This indicator does not light when it is turned off. The entire module measures 3.4 x 2.7 x 2.7 inches and has an open housing. The module needs to be isolated between the AC input terminal and the DC output terminal, and the isolation voltage is required to be 2500 volts DC for 1 second. The module has a nominal output of +24 volts DC and its output voltage is regulated to 20.4 to 27.6 volts DC, +/- 15% including noise and 5% AC ripple. The module has an output power of 31.2 W, a maximum output ripple of +/-5% 1200 mV peak-peak value, and a maximum output current of 1.3 amps. Its power consumption is 7 W and its heat dissipation is 23.9 BTU/ hour. The 1794-PS13 has an operating temperature of 0 to 55 degrees Celsius, a storage temperature of -40 to 85 degrees Celsius, and a relative humidity of 5 to 95 percent (non-condensing). The module has an operating vibration of 5 g at 10 to 100 Hz, an operating shock of 30 g, and a non-operating shock of 50 g.
