Cole Hersee FlexMod LVD modules preserve batteries, starting power

Cole Hersee Company is providing its new FlexMod LVD, a family of configurable electronic modules that protect batteries and battery-powered equipment.

FlexMod LVD ensures that vehicles will start by controlling non-essential loads that can kill a battery. The module is designed for fleets of emergency vehicles, delivery vehicles, buses, or utility trucks.

These modules automatically shut down non-essential loads when the battery runs low, and automatically restore non-essential loads when battery power returns to normal levels. Typical uses include idle reduction for work vehicles, NFPA 1901 Load Manager compliance for fire vehicles, and combined timer/voltage shutoff for police vehicles.

The FlexMod family has two inputs (one analog and one digital) and two solid-state outputs (one 10 amps, one 200 milliamps) that can be programmed to do almost any job.

Several standard units have been created for specific applications, including:

  • The 48610 Electronic Low Voltage Disconnect that preserves battery charge and protects battery banks

  • The 48636 Electronic Timer for Interior Lighting, which prevents internal lights inside a vehicle from being left on and draining the battery

  • The 48540 Smart Battery Isolator Controller, which monitors two battery banks and controls one or more relays or contactors to protect starting power

  • The 48541 Electronic Voltage Sensing Relay & Timer, which monitors both battery voltage and ignition status, shutting down non-critical loads when cutoff voltage is reached

Custom parameters can be programmed into one of the off-shelf modules at the Cole Hersee factory.
