Cole Hersee has introduced the Voltage Sensing Relay & Timer (VSRT), a new product in the FlexMod line.

The FlexMod VSRT conserves the starting power of a vehicle battery by shutting off auxiliary loads when 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 emergency vehicles. When a vehicle is left idling with active warning lights and other onboard loads, a battery deficit can arise, and the emergency vehicle cannot be restarted.

Cole Hersee said the FlexMod VSRT is ideal for police and emergency vehicles since it virtually eliminates the possibility of vehicle not reaching the next emergency situation due to a dead battery. The small device alerts the operator when starting voltage is low and then conserves power by cutting off any non-essential loads, such as air conditioning or exterior lighting.

Cole Hersee said solid-state technology is used in creating the FlexMod VSRT, providing long life and zero maintenance or replacement. Its service life exceeds 1 million on/off cycles, 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 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.
