1746-P3 Allen Bradley

1746-P3 Allen Bradley

is a Power Supply module. This module is part of the SLC 500 controller platform that is mainly used to provide power to the 1746 backplane to which the SLC 500 modules are attached to.

Features:

• This power supply module is located at the left-most area of the rack and does not occupy a chassis slot.
• It internally converts input power to a voltage level usable by the modules, specifically, converts an input supply voltage of 19.2…28.8V dc to an internal supply of 3.6 A at 5V dc and 0.87 A at 24V dc.
• The 1746-P3 is especially applicable to the SLC 500 Modular control system.
• It has a typical line power requirement of 90 VA with isolation of 600V ac RMS for 1 second.
• Pre-installed fuse which may be replaced with Allen-Bradley recommended 1746-F3 or any equivalent.
• Fuse sizes declared are used for end-devices only.
