Home | Battery Chargers | SBC-5A-M Smart Battery Charger


SBC-5A-M series are state of the art battery chargers featuring very high efficiency and low cost in a compact metallic casing. Chargers are designed to withstand high levels of disturbances found in the harsh automotive environment. Chargers are practically impossible to destroy, having overload, short circuit, high temperature and reverse battery protections. The overload protection is current limiting type, not hiccup. Hiccup protected chargers will turn-off in case of overload and will be incapable of charging an empty battery with their rated current. In case of a short circuit or overload condition, the SBC-5A-M charger does not shut-off and delivers simply the rated current, allowing a full-speed charge of an empty battery. In case of overheating, the charger will automatically reduce its output current and continue normal operation. Chargers offer automatic battery voltage detection. Thus the same module operates at 12V or 24V without the need of a manual selection, removing human errors.


SBC-5A-M chargers have universal input voltage range, enabling the use in all countries with nominal voltages ranging from 110VAC to 277VAC. The nominal output is fully available at all 90-305VAC range without derating. Chargers offer green mode of operation. The green mode consists on reducing the operating frequency when the load decreases. Thus, chargers reduce their losses helping protection of the environment. At very small loads, they enter into a burst mode to reduce the consumption further. Chargers feature very low power consumption at no-load mode, helping again the protection of the environment. The peak efficiency of chargers exceeds 92.5%, resulting in lower long-term operational costs. As an example, compared to a 24V/5A charger of 85% efficiency, with 30% average load and 20 years of operational life, SBC-5A-M will consume 700 kW-hour less electrical energy. This means approximately to 70 USD less energy expense per charger. The rectifier fail output is capable of driving a relay or transmitting the operational status to a control module which will give an alarm in case of failure.
