Cole Hersee introduced the Voltage Sensing Relay & Timer in the recently released FlexMod line.

The FlexMod VSRT conserves the starting power of a vehicle battery by shutting off auxiliary loads when either starting voltage drops to a low level, or a pre-set timer times out.

Excessive battery discharge is a problem that is sometimes unavoidable, particularly for utility and fleet vehicles. When a vehicle is left idling with onboard loads, a battery deficit can arise and make it impossible to re-start the vehicle.

The FlexMod VSRT helps eliminates the possibility of vehicles not starting due to a dead battery. The 4"x3"x1" piece of equipment alerts the vehicle operator when starting voltage is low and then temporarily cuts off any non-essential electrical loads, thus conserving power to start.

Cole Hersee uses solid-state technology in the creation of the FlexMod VSRT, providing long life and zero maintenance or replacement. Its service life exceeds 1,000,000 on/off cycles, operating for the entire lifetime of the vehicle, according to the company.

The device has a rating of 10A, and can handle many loads directly or drive a relay or solenoid for higher amperages. Overvoltage and overcurrent protective measures are also included, providing extra levels of assurance.

The VSRT is also weather resistant, waterproof and dustproof, allowing it to be mounted anywhere on the vehicle. With minimal wiring and a snap-in connector, it does not require any additional heavy or bulky hardware.
