l Two AC input channels that can automatically switch over, offering high reliability and stable system operation.
l By adopting switch-mode power supply technology, the output ripple is significantly reduced, effectively extending the battery’s service life.
l The charger and the control rectifier are designed in a mutually independent manner, so that in the event of a failure, the charger and the control rectifier can be interchanged.
l Adopting a high-quality, high-performance central monitoring unit that can reliably perform data acquisition and signal processing, among other functions;
l The high-frequency switching power supply employs an N+1 hot backup configuration, ensuring that the failure of any single module does not affect the normal operation of the system, thereby guaranteeing the overall system’s reliability and allowing it to easily meet the requirements of various systems.
l When the central control system fails and goes offline, the charging and rectification modules can continue to operate normally, ensuring that the power supply system remains functional.
l Automatic switching between equalization charging and float charging of batteries is achieved via the central monitoring system.
l Charge the battery strictly according to its charging curve, avoiding both overcharging and undercharging, which can effectively extend the battery’s service life.
l The charging voltage can be adjusted in a timely manner according to the ambient temperature, ensuring that the battery remains in an *** charging state.
l Replace the conventional silicon rectifier chain with a specially designed diode rectifier module to ensure high reliability of the step-down unit.
l The human-machine interface features fully Chinese-language display, a user-friendly, intuitive, and visually appealing interface that is easy to operate.
l The human-machine interface features functions such as parameter setting, status inquiry, and power on/off control.
l Open interface design with powerful communication capabilities, enabling “remote signaling, remote measurement, remote control, and remote adjustment” functions via the microcomputer communication interface. It can transmit relevant real-time data and alarm information according to user requirements.
l Reliable lightning protection and electrical insulation measures, coupled with an optional insulation monitoring device, enable real-time monitoring of the system’s insulation condition, ensuring both system and personal safety.
l The system design adheres to international standards such as IEC (International Electrotechnical Commission) and UL, ensuring robust reliability and safety.

The DC power system primarily consists of intelligent high-frequency switching power modules, a central monitoring unit, maintenance-free batteries, and feeder circuits. It boasts numerous advantages, including light weight, compact size, high efficiency, and zero pollution, making it an ideal replacement for conventional DC power supply systems. This system is particularly suitable for medium- and small-sized power plants, hydroelectric stations, various types of substations, switchgear rooms, and other applications that rely on DC equipment—such as petrochemical facilities, mines, railways, telecommunications, metallurgy, and high-rise buildings. It serves as the operating power source for high-voltage switchgear closing and opening operations, relay protection devices, automatic control systems, signaling devices, as well as for emergency lighting and DC power supplies used in control systems.
