PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-P4 is an SLC 500 Power Supply Module designed for industrial rack-mounted control systems. This power supply accepts input voltages of 85 to 132 volts AC or 170 to 265 volts AC. The unit operates across a line frequency range of 47 to 63 Hz. It features a line power requirement of 190 VA at 120V AC and 230 VA at 240V AC.
The module delivers internal current capacities of 10 Amps at 5V DC and 2.88 Amps at 24V DC. It manages a maximum startup inrush current of 45 Amps for stable electrical performance. Terminal blocks accommodate up to two number 14 AWG wires per connection point. An integrated non-replaceable internal fuse provides continuous overcurrent protection for system hardware.
