Functional Wiring Diagram:


This power supply provides an isolated 13.5VDC source from a nominal 24VDC input. In addition, this power supply is equipped with 2-stage lightning protection on both the input and output. This eliminates the need for any external protection and you do not have to find space to install the protection.

This power supply mounts directly onto standard AAR terminal blocks and all connections are made through the board itself. This allows for easy mounting and replacement, as well as making it so you never need to disconnect the wires from the the AAR Terminal Block.

The unit has an onboard dedicated fuse that will disconnect the supply from the House batttery so it will not take your facility down in case of a failure. The fuse is socket mounted for easy replacement. The fuse is a standard ATO automotive style available at any auto parts store.
