Voltage sensing relay and timer


Boston, Mass., March 24, 2011—Cole Hersee has introduced the Voltage Sensing Relay and Timer (VSRT), a new product in the just-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 utility and fleet vehicle.

The FlexMod VSRT is for utility and fleet vehicles, because is virtually eliminates the possibility of vehicles not starting due to a dead battery. This small (4 inch x 3 inch x 1inch) 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 utilizes 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. This 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 completely weather resistant, waterproof and dustproof, allowing it to be mounted anywhere on the vehicle while remaining reliable and functional. With minimal wiring and a snap-in connector, it does not require any additional heavy or bulky hardware, so installation is easy and simplified.
