1756-PA75

The Allen Bradley 1756-PA75 functions as a robust power supply module within the ControlLogix series. This unit accepts input voltages of 120 or 240 volts AC with a current rating of 100 volt-amperes. The overall input power rating is established at 100 watts, ensuring sufficient energy delivery for connected devices.

In terms of output capabilities, this power supply accommodates multiple current outputs: 2.8 amps at 24 volts DC, 13.0 amps at 5.1 volts DC, 4.0 amps at 3.3 volts DC, and 1.5 amps at 1.2 volts DC. It can handle a maximum output power of 75 watts, suitable for various applications. The initial inrush current can peak at 30 amps, providing adequate support for devices that require transient power surges.

Additionally, the isolation voltage specified for operation is 250 volts (continuous), ensuring electrical safety and preventing undesired interference. With an open-style enclosure, this module is designed for compatibility in standard environments. The temperature operating range is from 0 to 60 degrees Celsius, allowing it to function efficiently in various conditions.

The hold-up time, an important specification for maintaining functionality during short power interruptions, is rated for 2 cycles at 85 volts AC at 60 Hz, extending to 6 cycles at 120 volts AC and 20 cycles when operating at 220 volts AC. Altogether, the 1756-PA75 provides versatile and reliable power for ControlLogix applications.
