Featuring selectable timer delays, multiple sensing modes, and LED voltage indicators, it prevents battery drain and voltage damage, ensuring reliable operation of two-way radios, laptops, and mobile data terminals. ## Description The Havis ChargeGuard Select CG.X automatic on/off timer switch acts as a vehicle power management system by automatically turning on mobile equipment when starting the motor. The 12 volt negative ground ignition sensing timer switch is designed for two-way radios, mobile data terminals, laptop computers and other mobile computing devices. The ChargeGuard delay timer switch has a selectable timeout delay. When turning the motor off, equipment can stay on from 5 seconds to infinity depending on what is programmed. This programmable timer delay switch comes pre-programmed with a two hour delay as the default setting. This on/off timer switch wires directly to the battery or ignition switch in your vehicle. The ChargeGuard features your choice of sensing mode, automatic detection mode (AC), isolated alternator detection, voltage rise detection (DC only), or direct ignition mode (HL), depending on your preference. The Havis ChargeGuard Select delivers higher productivity and lower maintenance costs for your two-way mobile communication. Review: Works great - I bought these to control power to a siren amplifier and a mobile radio. I had problems with my truck battery dying from leaving constant power to them. I set these to come on when it senses power and to go off 5 seconds after it loses power. They work great and I don’t have to worry about turning stuff off or coming out to a dead battery.
