Datakom’s new industry leading smart battery charger SBC-5A combines very high efficiency, wide input range, 4-stage smart charging, automatic voltage detection, reverse battery protection in a compact and low-cost package. The device is designed using state of the art technology and is able to withstand the high levels of electromagnetic noise and pulses found in challenging industrial environments.

High Efficiency

The peak efficiency of chargers exceeds 92.5%, resulting in lower long-term operational costs. The electronic components in the SBC-5A are state of the art and they represent the highest industry standards in efficiency and environmental friendliness. It can save 700kWh of energy due to its very high efficiency, which will amount to $70 per charger in 20 years under 30% average load.

Smart Charging

The SBC-5A has a microprocessor controlled 4-stage charging system, making it more advantageous compared to traditional 2-stage battery chargers. The smart charging algorithm keeps the battery charged at 100% capacity and provides maximum battery life by applying an automatic periodic regenerative charging cycle. Until the battery is fully charged, SBC-5A applies the highest possible charging voltage at its battery terminals, then continues applying the float voltage. This ensures that all the cells remain at full charge. The regenerative charging cycle allows full charge at the lowest possible float voltage, thus increasing battery life. This feature can be toggled on or off from the DIP switches on the device’s circuit board.

Auto Voltage Detection

SBC-5A is able to automatically detect the battery voltage and adjust its output. If the device measures less than 18VDC at its output terminals, it will operate in 12V mode. If the output voltage is higher than 18VDC, the SBC-5A switches to 24V mode. This reduces the number of inventory items as the same charger can be used to charge both 12V and 24V batteries.

Environmentally Friendly

The SBC-5A helps protect the environment with its green mode of operation. The charger reduces the operating frequency when the load decreases, thus reducing losses. At very small loads, the charger enters burst mode to further reduce energy consumption. In no-load mode, the charger has very low energy consumption to help with environmental protection. The SBC-5A is also RoHS compliant.

Robust, Safe and Durable

SBC-5A offers various types of protections against overload, short-circuit, high temperature and reverse battery connection. The overload protection is current limiting type to allow the SBC-5A to quickly charge an empty battery to full. The unit has a rectifier fail output which can drive a relay or transmit its operational status to an external control or alarm module. Reverse battery protection is provided by a mosfet transistor used as a power switch. This allows the protection to be so quick that a reverse battery may even be connected during charger operation without any harm. The high temperature protection decreases the current output and resumes operation. All materials and components used in SBC-5A are resistant to high temperatures. This helps increase the operational lifetime of the device.

Automatic Power Derating

The SBC-5A automatically limits its current output at high temperatures. A correctly installed charger with sufficient airflow will keep providing the maximum current supply until 50°C at 230VAC. After this, it will gradually decrease its output, reaching 0A at 85°C. The SBC-5A will resume operation as soon as the internal temperature falls below 85°C

Wide Input Range

SBC-5A’s wide input range allows it to be used in any grid ranging from 100 to 277VAC, decreasing the number of inventory items further for global resellers and genset manufacturers.

Battery Voltage Selection

SBC-5A offers output voltage selection for different battery types. The defined types are Li-Ion, Ni-Cd, and two different types of Lead-Acid batteries. For 12V batteries, the float charge voltage varies from 13.2VDC to 14.0VDC. The absorption charge voltage varies from 13.7VDC to 14.5VDC. For 24V batteries, float charge voltage varies from 26.4VDC to 28.0VDC. The absorption charge voltage varies from 27.4VDC to 29.0VDC. These can also be selected from the DIP switches.
