Havis ChargeGuard Select Control Module: Premium Voltage Protection for Mobile Electronics

The Havis ChargeGuard Select Control Module is the ultimate safeguard for your mobile electronics, engineered to shield sensitive devices from voltage anomalies that can cause costly damage and kill batteries. Built for the rigors of mobile professionals—fleet vehicles, public service units, field technicians, and on-the-road equipment—the ChargeGuard Select delivers reliable, intelligent protection in a compact, automotive-grade package. By actively monitoring the vehicle’s electrical system and intercepting fluctuations before they reach critical loads, it minimizes downtime, extends battery life, and keeps your essential devices ready when you need them most. With a focus on ease of integration, durability, and configurable protection thresholds, this module is the smart heartbeat of a resilient mobile power system.

• Comprehensive voltage protection for every load: Guard against over-voltage, under-voltage, voltage transients, and load-dump events that are common in demanding mobile environments. The ChargeGuard Select defends sensitive electronics—from radios and tablets to CCTV cameras and sensors—so they stay online when the vehicle power system is unstable.
• Smart, auto-reset fault handling: When a fault is detected, the module isolates the fault and automatically resets once the electrical conditions return to safe levels. This minimizes nuisance shutdowns and reduces manual intervention, keeping critical equipment up and running without constant monitoring.
• Rugged automotive-grade design: Built to endure vibration, temperature swings, and the dusty, humid conditions typical of fleet and service vehicles. Its compact footprint is designed to tuck neatly behind dashboards, in instrument panels, or within power distribution enclosures without compromising space or airflow.
• Seamless integration with Havis ecosystems: Engineered to pair perfectly with Havis mounting solutions, power distribution modules, and vehicle-off accessories. The plug-and-play nature simplifies installation, shortens downtime, and provides a cohesive, professionally installed power protection system for your mobile office or command center.
• Energy-efficient and load-ready: Designed to minimize parasitic draw while actively protecting loads, helping to preserve battery health and extend run-time for essential equipment during extended deployments or offline operation.

how to install Havis ChargeGuard Select Control Module

• Identify a secure mounting location within the vehicle or cabinet that is protected from water spray and excessive heat, while keeping wiring pathways clear for power and load connections.
• Connect the ChargeGuard Select to the vehicle’s 12–24 V DC power supply using the supplied connectors and follow the vehicle’s power distribution practices, including proper fusing and protection per local electrical codes.
• Route the load wiring from the power distribution point to your protected devices (radios, cameras, tablets, sensors) and connect each load to the labeled outputs on the ChargeGuard module as specified in the installation guide.
• Configure protection thresholds and status indicators according to your equipment needs. If the module offers programmable options, set target voltage ranges, delay times, and alarm behavior to balance protection with uptime.
• Test the installation by powering up the vehicle and verifying that connected devices remain stable through normal operation and during simulated voltage events. Confirm automatic fault reset functions properly and monitor LED indicators or CAN bus feedback if available.

Frequently asked questions

What does the Havis ChargeGuard Select Control Module protect?

It protects mobile electronics connected to a vehicle’s electrical system from voltage disturbances such as spikes, dips, load dumps, and reverse polarity. This helps prevent premature device failure and battery drain, ensuring critical equipment remains operational in field conditions.
