Relay conserves starting power of vehicle batteries

Oct. 20, 2010 - The Cole Hersee FlexMod Voltage Sensing Relay & Timer (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. This small (4”x3”x1”) piece of equipment alerts the vehicle operator when starting voltage is low and then cuts off any non-essential loads, such as air conditioning or exterior lighting, thus conserving power to start. The VSRT is weather resistant, waterproof and dustproof, and was designed using solid state technology to provide a long life and zero maintenance or repaclement. 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. For more information visit
