The REDARC BCDC1240D Dual Input In-Vehicle Battery Charger is an advanced, versatile charging solution designed to ensure your auxiliary batteries are always fully charged and ready for use. This charger is perfect for off-grid adventures, providing reliable power for all your 12V equipment. With the ability to charge from both your vehicle's alternator and solar panels simultaneously, the BCDC1240D ensures your batteries maintain optimal performance and longevity.

Key Features:

Dual Input Charging:

• Vehicle and Solar Inputs: The BCDC1240D can charge from both the vehicle's alternator and unregulated solar panels simultaneously, maximising charging efficiency. This dual-input capability ensures you always have a reliable power source, whether driving or stationary.

• Maximum Power Point Tracking (MPPT): The built-in MPPT solar regulator optimises the power output from solar panels, ensuring maximum charge even in low light conditions. MPPT technology adjusts the electrical operating point of the solar panels to maximise energy harvest.

Advanced Charging Algorithm:

• Multi-Stage Charging: The charger employs a multi-stage charging algorithm, providing Boost, Absorption, and Float stages to ensure batteries are charged to their full capacity. The Boost stage delivers a high current to quickly bring the battery voltage up, the Absorption stage holds the voltage at a set level to fully charge the battery, and the Float stage maintains a low voltage to keep the battery topped up.

• Soft Start Technology: For smoother and safer battery charging, the BCDC1240D incorporates soft start technology, which gradually increases the current to protect your batteries and the charging system. This feature is particularly beneficial for protecting sensitive battery components from sudden inrush currents.

Durable and Reliable:

• Fully Sealed and Fan-Free Cooling: The BCDC1240D is designed with fully sealed electronics and a fan-free cooling system, making it resistant to dust, water, and vibrations. This durability ensures the charger can withstand harsh environmental conditions, making it ideal for off-road and adventure vehicles.

• Compact Size: Its compact design allows for flexible installation in various locations, including the engine bay, vehicle cabin, or trailer. The small footprint means it can be installed in tight spaces without compromising performance or accessibility.

Compatibility:

• Wide Range of Batteries: The BCDC1240D is compatible with all common types of 12V automotive lead-acid batteries, including AGM, gel, standard lead-acid, and calcium, as well as lithium iron phosphate (LiFePO4) batteries. This flexibility makes it a versatile choice for different battery types and applications.

• Wide Input Voltage Range: The charger supports an input voltage range from 9 to 32 volts, making it suitable for both 12V and 24V vehicle systems. This broad compatibility ensures it can be used with a variety of vehicles and setups.

Safety and Protection:

• Battery Isolation: The BCDC1240D ensures your main battery is not over-discharged by isolating it from the auxiliary battery, protecting your vehicle's starting battery from deep discharge.

• Fault Detection and Protection: The charger includes comprehensive protection against voltage spikes, overheating, and reverse polarity connection. These safety features safeguard both your batteries and the charger, ensuring reliable and safe operation.

Additional Features:

• Green Power Priority: This feature ensures the unit will always supply as much power as possible from the solar input before supplementing this with power from the vehicle input. This maximises the use of renewable energy and reduces the load on your vehicle's alternator.

• Dual Battery Isolation: Incorporates advanced dual battery isolation to prevent the auxiliary battery from draining the main battery, ensuring your vehicle is always ready to start.

• Compact and Lightweight: Weighing only 1 kg and with dimensions of 165 x 120 x 37 mm, the BCDC1240D is easy to install in a variety of locations.

Vehicle-Specific Mounting Brackets:

• Customised Brackets: REDARC offers a range of vehicle-specific mounting brackets designed to simplify the installation process. These brackets use pre-existing mounting points on the vehicle, minimising the need for modifications and ensuring a secure, professional installation.

• Bracket Models: Some of the available brackets include the BCDCMB-001 for Toyota LandCruiser 200 Series (11/2008 – onwards) and the BCDCMB-008 for Toyota LandCruiser J100 and J105 Series (1998 - 2007). Universal brackets are also available to fit various other vehicle models.

• Easy Installation: The brackets are designed for easy installation, reducing setup time and ensuring the charger is securely mounted in an optimal location for cooling and accessibility.
