Cole Hersee Company introduces its new Low Voltage Disconnect (LVD) Switch. Cole Hersee’s LVD Switch eliminates dead batteries by automatically disconnecting non-critical loads from a battery when the battery falls below a predefined threshold. When the battery voltage is restored, the switch automatically restores the functionality of the ancillary equipment. Ideal for trucking applications, the LVD Switch prevents the loads from disconnecting during starting. The switch provides over-current, short-circuit and over-temperature protections to ensure a safe and reliable operation.
