Havis CGX ChargeGuard-Select Intelligent Vehicle Power Management System

The Havis CGX ChargeGuard-Select is an intelligent vehicle power management system designed to prevent dead batteries and protect mobile electronics in commercial and emergency vehicles. This self-contained unit provides automatic circuit protection for 12-volt negative ground vehicle power systems, ensuring your equipment is always ready when you need it.

Key Features:

• Programmable timer with selectable timeout delay from 5 seconds to 18 hours (default setting: 2 hours)
• Automatic on/off switching for mobile equipment when starting or stopping the vehicle
• Multiple sensing modes: automatic detection (AC), isolated alternator detection, voltage rise detection (DC), or direct ignition mode
• LED indicators for under and over voltage conditions
• Handles up to 30 amps for laptops, two-way radios, mobile data terminals, and other devices
• Protects against voltage anomalies and prevents battery drain
• Compact design: 3.7 inches wide × 1.3 inches low profile height

The ChargeGuard-Select automatically turns on mobile equipment when the engine starts and shuts off accessories based on battery voltage and elapsed time after the vehicle is turned off. If battery voltage drops too low, the system automatically disconnects peripherals to ensure enough power remains to start the vehicle. Perfect for fleet vehicles, emergency response vehicles, and commercial applications where reliable power management is critical.
