Purkeys’ Dual Shield is designed to simplify adding electrical devices to heavy-duty vehicles and protect the source that powers them. The Dual Shield provides a single source with multiple protected ports for electrical devices and gives the vehicle two levels of protection to help counteract parasitic loads from the electrical systems: a low-voltage disconnect and a timed disconnect. The LVD shuts off the device when a set voltage is reached, keeping batteries from becoming too discharged to start the vehicle, while the timed disconnect shuts off running devices within an hour after the ignition is turned off. LEDs show drivers when there is power running through the system or when devices have been shut off.
