Low Voltage Disconnect Switch

Description

Cole Hersee Company, a leading manufacturer of electrical and electronic products for the vehicle industry, 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.

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. Additionally, Cole Hersee’s LVD Switch is resistant to vibration and mechanical shock, as well as withstands contamination from moisture, dust or salt spray.

The LVD Switch extends battery life. The switch has a 200A at 12V DC rating, and comes with a manual override option to allow users to make or break the connection regardless of the battery voltage.
