Magnum Energy AC Load Diversion Controller ACLD-40

Magnum Energy AC Load Diversion Controller ACLD-40



Availability: Out of stock SKU: ACLD-40 Category:


The ACLD monitors the battery voltage of a backup battery bank, and if the voltage rises to a predetermined level, the ACLD connects a diversion load of sufficient size, to the battery or energy source to prevent the battery voltage from increasing any further. The controller will continue to engage and disengage the load as often as necessary to prevent battery overcharge.

An AC Load Diversion controller is used to divert excess energy to an AC load in an effort to keep the battery bank that is connected to a back-up inverter from being overcharged, when used in an AC Coupled application.

Magnum Energy Part Number: ACLD-40


  • Controls up to 4000 watts of excess power to prevent battery over-charge
