- Includes an on board smart 24 V battery charger with 12 V and 24 V outputs
- Can be manufactured to include a wide variety of radios, cell modems and other communication units or they can be user installed in the field
The M-2979 includes the capability to change out the Recloser Control and Cabinet as one component. The M‑2979 Recloser Control Cabinet and M-7679 R-PAC combination includes all the required interface connections and external communications capabilities that are necessary to replace an existing recloser control.
