No more dead batteries!
The FlexMod electronic voltage sensing relay & timer monitors both battery voltage and ignition status, shutting down non-critical loads when the cutoff voltage is reached, or at the set time after the ignition is turned off. It is a timer and voltage sensor in one easy-to- connect unit.
Ideal for use in emergency vehicles, the unit senses both voltage and time; after the vehicle engine is turned off, if either the cutoff voltage or time limit is reached, the Voltage Sensing Relay & Timer FlexMod will shut down the auxiliary loads. The dual technology in package provides double protection.
The FlexMod electronic voltage sensing relay & timer opens up options for mounting in a small space, and simplifies wiring and other components.
Cole Hersee FlexMod Voltage Sensing Relay and Timer Series Features & Benefits ▲
- Ideal for emergency vehicles and many other applications
- Protects starting battery from being drained by auxiliary loads
- Compact design (4 x 3 x 1 ), and solid-state unit is waterproof, dustproof and vibration-proof. Mounts anywhere on a vehicle, even places where road-splash is a problem. Sealed to IP67 standard
- Preserves starting power; eliminates downtime and jump starts due to dead batteries. Simultaneous time and voltage sensing protects starting, even when the vehicle is running “in deficit”
- Monitors voltage and time simultaneously, providing double the protection to batteries. Battery will not be drained if battery voltage gets low before timer has run out.
- 10A rating means it can handle many loads directly or drive a relay or solenoid for higher amperage
- Unit is auto-ranging – senses 12 Vdc or 24 Vdc systems
- Unit can be used as-is, with factory-programmed presets, or can be programmed by dealers to a broad scale of values
