{"product_id":"mg-afc300-alternator-field-controller","title":"MG AFC300 Alternator Field Controller","description":"The MG AFC 300 is an alternator field controller that lets a standard engine alternator charge an MG lithium-ion battery bank safely. By regulating the current in the alternator field winding it follows the charge setpoints sent by the connected MG BMS over the NMEA2000 CAN-bus, so the battery is always charged under optimal conditions. An integrated shunt continuously measures alternator current and temperature and reduces output before the alternator can overheat.\n\nBuilt-in load dump protection clamps any voltage overshoot and stops charging immediately if a fuse fails or the BMS main safety contactor opens, protecting the alternator and connected electronics. The AFC 300 suits 12 V, 24 V and 48 V systems and works with any alternator that has external field control, automatically detecting the field type and polarity so no special cable harness is needed. Multiple units run in parallel, and Bluetooth allows quick setup and monitoring through the MG Connect app.","brand":"MG Energy Systems","offers":[{"title":"Default Title","offer_id":56272814506324,"sku":"MGAFC480300","price":1132.8,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/hme.sprechen.dev\/products\/mg-afc300-alternator-field-controller","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
