Cole Hersee's SureStart compact low-voltage disconnect switch electronically senses battery level to conserve power, disconnecting noncritical loads before the battery power falls to a level insufficient for starting and automatically restoring the load when the power level is re-established. The unit is rated at 100 A at 12 V dc and works with 12- or 24-V. Benefits include a reduction in service calls from dead batteries and a prevention in permanent battery damage due to overcranking. Sealed to IP67, the solid-state SureStart can be mounted in harsh environments and is impervious to vibration. With an optional manual override, the unit replaces solenoids and automatically warns vehicle operators of imminent power cutoff to noncritical loads. It also protects batteries and onboard electronics against over-temperature and over-current, according to Cole Hersee.
