1756-PA75K

The Allen-Bradley 1756-PA75K module is a 1756 ControlLogix power supply module. The input voltage range for the 1756-PA75K module is from 85 to 265 Volts AC. The nominal input voltage is 120 to 240 Volts AC. The supported range of input frequencies is from 47 to 63 Hertz. The maximum input power is 100 VA or 100 Watts. The maximum output power level is 75 Watts at 0 to 60 degrees Celsius. The maximum inrush current to the 1756-PA75K module is 20 Amps. The hold-up time, which is the time interval between the input voltage removal and the DC power failure for the 1756-PA75K module is 2 cycles at 85 Volts AC and 60 Hertz, 6 cycles at 120 Volts AC and 60 Hertz, and 20 cycles at 220 Volts AC and 60 Hertz. The current capacity for the module is 1.5 Amps at 1.2 Volts DC, 4 Amps at 3.3 Volts DC, 13 Amps at 5.1 Volts DC, and 2.8 Amps at 24 Volts DC. The rated isolation voltage is 250 Volts AC continuous.

The approximate weight of the 1756-PA75K module is 2.1 pounds and its dimensions are 5.51 x 4.41 x 5.71 inches. The module is installed on the left side of the 1756 chassis. Series B and Series C Allen-Bradley chassis which are compatible with the 1756-PA75K module include the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and the 1756-A17. The recommended wire size for use with the 1756-PA75K is 14 AWG solid or stranded copper wire. The copper wire should be rated for 90 degrees Celsius. The enclosure of the module is open and it complies with the T4 North American temperature code.
