Introduction to FLT Battery Chargers
FLT Battery Chargers are advanced AC/DC rectifiers designed to charge high-capacity battery packs while providing stable DC voltage to critical loads. They utilize a microprocessor-controlled thyristor bridge and LC filter units to ensure low ripple and stable output. Optional Silicon Dropper Units can be added for voltage regulation.

Components and Operation
The chargers consist of an input power transformer, thyristor rectifier unit, and electronic control units. The power transformer adjusts network voltage, while the thyristor bridge converts AC to DC and adjusts voltage. A microprocessor-based management board controls the charging process, which is automatic and requires no operator intervention.

Key Features

Input Isolation Transformer
Durable thyristor technology
Three-phase and single-phase input options
High power capacity up to 500 Kva
Compatible with Ni-cd, Lead Acid, and Stationary batteries
Constant Voltage/Current Charge Function
Float and Boost Charge Facilities
Microprocessor-based management
Various protection features (e.g., DC Earth Leakage, Overload, Over Temperature)
Efficiency between 85-95%
Operator Panel with LCD Display
TS EN ISO 9001: 2015 Quality Certified

Optional Features

Battery Deep Discharge Protection (LVD)
DC Voltage Dropping with Silicon Dropper (SDU)
Dry Contacts for Automation
Battery Temperature Compensation
Equalization/Commissioning Charge
Parallel/Redundant Operation
Battery Reverse Polarity Protection
Input Harmonic Filter
DC Distribution Fuses
7” Touchscreen Operator Panel
ETHERNET and MOD-BUS RTU interface

Charging Algorithms
FLT Battery Chargers employ a Constant Current/Constant Voltage charging algorithm to optimize battery performance. The process begins with a soft-start curve, transitioning between constant current and voltage modes as needed. Float and Boost Charge functions are available, with manual boost options.

Additional Features

Galvanic Isolation Transformer for safe operation
Earth Leakage Monitoring
Parallel Connection and Load Sharing capabilities
Production at all industrial voltages
Remote Monitoring and Management via Ethernet or MOD-BUS RTU

Technical Specifications
FLT Battery Chargers are available in various models with different input and output voltage options, efficiency ratings, and protection functions. They are designed for industrial environments with specific environmental and cabinet specifications.

Conclusion
FLT Battery Chargers offer a robust solution for industrial battery charging needs, with a range of features and options to ensure efficient and safe operation. For more detailed information and custom solutions, contact the sales representative or visit the company's website.

Constant Current / Constant Voltage Charging Algorithm FLT Battery Chargers have a special charging procedure to keep the batteries at the highest performance. Vfloat Battery Charge Voltage FLT Battery Charger increases the DC output voltage to its nominal value with a soft-start curve. Constant Current Function becomes active when battery charging starts. In Constant Current Mode, current that is supplied to the batteries remains stable at the Battery Charge Current value set by the operator. When the battery voltage reaches its nominal value, the Constant Voltage function is activated. Battery...

Battery Deep Discharge Protection (LVD) (optional) FLT Battery Chargers have load disconnection unit for battery deep discharge protection. When the measured battery voltage falls below the LVD Voltage set by the operator, the LVD contactor cuts the load current. There is dry contact information and light signal for LVD protection. Silicon Dropper Unit (optional) Silicon Dropper unit can be added to FLT Battery Chargers to regulate the DC voltage on the load supply line. Silicon Dropper units that are designed in accordance with DC load parameters and customer demand can be used in 2 pcs or more....
