Back-Up Power Unit
BACK-UP / POWER UNIT Back-Up Power Unit
Military vehicles and critical defense systems depend on continued electrical availability even after the primary vehicle supply is switched off. The Back-Up Power Unit maintains power for connected fire extinguishing systems for approximately 2 to 8 hours, helping preserve system readiness during loss of main power. Its dedicated maintenance isolation function also allows the backup supply to be disconnected when service procedures require the electrical system to be safely separated.
Backup electrical support for fire extinguishing systems when the primary vehicle power source is unavailable.
Power Continuity for Critical Fire Suppression Functions
The Back-Up Power Unit provides an independent source of electrical support when the vehicle or platform's primary supply is no longer available. For fire extinguishing systems, the unit is designed to maintain sufficient power for approximately 2 to 8 hours after the main vehicle power has been switched off.
This backup capability helps keep essential suppression functions electrically available during periods when the primary source cannot support the connected system.
Controlled Power Isolation During Service Procedures
A dedicated maintenance toggle switch allows the backup supply to be intentionally disconnected when electrical isolation is required. This function is intended for procedures such as maintenance work, component replacement, battery boosting and welding.
Separating the backup source during these operations provides technicians with direct control over power availability to the connected system.
