Description of 1746-P2

The Allen-Bradley 1746-P2 is a power supply of the SLC 500 series with an input voltage of 120/220V AC. The 1746-P2 is designed to be inserted into an SLC 1746 modular chassis which has varying sizes of 4, 7, 10 or 13 slots to meet the needs of your application and the necessities of the modular hardware component. The 1746-P2 can allow 3 chassis to be interconnected for a maximum interconnection of 30 modular slots. The power supply should be installed in the left-most slot of the chassis assembly. The 1746-P2 also uses a 14 AWG size of wire for every terminal.

The line voltage for the 1746-P2 ranges from 85-132V AC or 170-265V AC at 47-63 Hz. Internal current capacity for the power supply at 5V measures 5A and current capacity at 24V measures 0.96 A. The user current capacity for the 1746-P2 is 0.2 A at 24V DC. Additionally, the maximum inrush current for the power supply is 20A. The input power limit for the 1746-P2 is 42W, with a limited current up to 20V. Distinct input power for the power supply is 110 VA. The 1746-P2 has a user current output of 0.2A at 24V DC. The user voltage output of the 1746-P2 is not constant and it ranges from 18-30 V DC.

Operating temperatures for the 1746-P2 range from 0-60 degrees Celsius (32-140 degrees Fahrenheit). The current capacity for the power supply is derated by 5% in temperatures greater than 55 degrees Celsius (131 degrees Fahrenheit).

About 1746-P2

The Allen-Bradley 1746-P2 module is a power supply module for the SLC 500 systems. It supports an internal current capacity of 5 Amps at 5 Volts DC and 0.96 Amps at 24 Volts DC. The 1746-P2 power supply module can be installed with terminal screws with a maximum torque of 1 N-m or 8.8 pounds on an inch. The terminals on this power supply module are isolated but not fused and they provide 200 milliamps and 24 Volts DC of power. The line voltage ratings on the 1746-P2 power supply module are 85 to 132 Volts AC and 170 to 265 Volts AC at a frequency of 47 to 63 Hertz. Its typical line power requirement rating is 180 Volts-Amps. This power supply can be protected by a 1746-F2 fuse or an equivalent fuse.

The Allen-Bradley 1746-P2 SLC 500 power supply module can operate within a temperature range of 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit, but its current capacity will derate by 5% at a temperature above 55 degrees Celsius or 131 degrees Fahrenheit. Its user power voltage range is from 18 to 32 Volts DC at a nominal voltage of 24 Volts DC, its user power current capacity rating is 200 milliamps, and its maximum user-supplied overcurrent protection rating is 15 Amps. The CPU hold-up time for the 1746-P2 power supply module is 20 milliseconds at a full load and it is 3000 milliseconds with no load. It has been certified by the UL, C-Tick, and C-UL standards and by several of the CE regulations and standards.
