Description
CB12245AJ – 12V/24V 6A/5A 120W DIN Rail Battery Charger with CANBus
The CB12245AJ is a versatile DIN rail battery charger that supports both 12V and 24V operation through simple jumper configuration. Delivering up to 6A at 12V or 5A at 24V, it combines efficient IUoU multi-stage charging with constant voltage and constant current modes for optimal performance across multiple battery chemistries. With Battery Care technology, the charger provides Boost, Absorption, Float, and Recovery stages to ensure safe charging, extended battery life, and recovery of deeply discharged batteries.
Designed for modern applications, the CB12245AJ features CANBus J1939 communication, allowing seamless integration with advanced monitoring and control systems. It also includes a power supply function, enabling the unit to operate as a regulated DC power source when required. Real-time diagnostics with LED indicators and relay contacts provide immediate fault signalling, ensuring reliability and ease of maintenance in critical systems.
Compact and efficient with a conversion efficiency of up to 90%, the CB12245AJ is built for DIN rail or wall mounting and protected to IP20 standards. It includes comprehensive protections against short-circuit, overload, overheating, reverse polarity, and battery disconnection. Its ability to support Lead Acid, Gel, Ni-Cd, and optional Li-Ion batteries makes it a flexible solution for industrial, transport, and SCADA environments where robust power management is essential.
