A FCBC battery charger stands for Float Cum Boost Charger and is a type of industrial power management system designed to provide uninterrupted DC power to critical loads while efficiently managing battery charging in two distinct modes. These chargers are commonly used in applications such as electrical substations, telecommunications, and power plants where a reliable backup power supply is essential.
Operating ModesThe key feature of an FCBC charger is its ability to automatically switch between two modes of operation:
- Float Mode: This is the normal, continuous operation mode. The charger provides a constant, regulated DC voltage to power the connected load and simultaneously delivers a low "trickle" current to the battery bank to keep it fully charged and compensate for self-discharge without overcharging it.
- Boost Mode: If the battery has been heavily discharged (such as after a power outage), the charger automatically switches to Boost mode. In this mode, it delivers a higher voltage and current to rapidly restore the battery's capacity to full charge. Once the battery reaches the desired charge level, the system automatically reverts to Float mode.
Key Benefits
- Uninterrupted Power: Ensures continuous DC power supply to critical systems even during AC mains failure, using the battery bank as backup with zero transfer time.
- Battery Health: The dual-mode charging optimizes the charging process for different battery states, which helps extend the lifespan of the connected batteries by preventing both overcharging and deep discharge.
- Versatility: FCBC chargers are compatible with various battery types, including Lead Acid, VRLA (Valve Regulated Lead Acid), and Tubular batteries.
- Robust Design: Built for demanding industrial environments, these chargers often include essential safety features like over-voltage protection, short-circuit protection, and reverse polarity protection.
