Most inverters have a low voltage disconnect (LVD) that are made to protect just the inverter, but Purkeys’ inverters can protect the vehicle and the inverter with its programmable LVD.

Inverters take DC power from tractor batteries and convert it to 110 VAC power. This lets drivers operate devices such as laptops and microwaves while on the road.

Most inverters’ LVDs are set between 8 and 9 volts. When the inverter shuts off at this point the vehicle batteries are so discharged that they can’t start.

Purkeys’ inverters come with a programmable LVD. It’s set at a much higher voltage so the vehicle batteries won’t become discharged too deeply. This can help fleets avoid costly jumpstarts.

For example, a LVD set at 12.3 volts will allow the driver to enjoy all their in-cab comforts, while still protecting the vehicle’s electrical systems and allowing enough power to start. If the voltage drops below 12.3 a red light above the inverter’s power switch will flash and the inverter will shut off. This blinking light indicates the inverter shut off because the input voltage dropped below 12.3 volts.

To turn the inverter back on, the driver must start the vehicle and reset the inverter. The inverter has to register an input voltage above 13.3 before it will power on.

Purkeys’ inverters can help fleets and drivers by:

  • Protecting the vehicles electrical systems
  • Avoiding costly jump starts
  • Keeping drivers happy with the comforts of home on the road
