DMP 323 Wire-In Transformer

The DMP 323 is a 56 VA, 16 VAC wire-in transformer built to power DMP control panels that charge two or more batteries. It ships mounted on a mounting plate, sized for installation inside a large enclosure rather than the panel's stock backbox — the right call when a dual-battery setup outgrows the standard power budget.

Compatibility

The 323 is designated for use with DMP XR Series panels and is confirmed suitable for XT75 and XR panels specifically. If your install is a single-battery XR configuration, verify whether your panel's standard transformer already covers the load before adding this unit — the 323 is intended for the higher-draw, two-or-more-battery case.

Installation Notes

Mount the plate-mounted assembly inside a large enclosure — it is not designed to fit inside compact panel cans. Confirm enclosure clearance before rough-in, since the mounting plate adds depth and footprint beyond a standard in-cabinet transformer.

Model 323 pairs with the rest of the DMP catalog for panel power planning. For broader system design, review a power supplies selection guide before finalizing battery count and charging load, and check access control panels compatible with XR-series wiring if you're speccing a full install. Pair this transformer with the correct enclosures line for large-cabinet mounting.
