Sichuan Changhong Battery Co., Ltd. has engaged in system project design, develop industrial and miniaturization power supply for communication device. And the products of Changhong Battery are widely used in oil field, pressure station , communication base station, etc. and exported to Europe, Southeast Asia and other countries and regions.
On the basis of the characteristics of industrial products, the UPS systems developed by Changhong Battery adopt split type design and standard cases design for charger module( switching power supply and controller), inverter module and system so as to be easy for users to install. Charger module adopts advanced high-frequency soft switching technology and active power factor correction circuit, which makes it high efficiency. There is a built-in high-performance microprocessors in charging module, and the charging module adopts all-digital control, and has standard RS232, RS485 interfaces, which can not only realize local control, but also achieve remote control through the LAN interface. Charging module can be used in parallel, and load sharing capability is better than 5%. Inverter module adopts microprocessor control technology and SPWM pulse width modulation technology to improve the reliability of the module, and uses a variety of means of protection, such as over power protection, automatic restart after power reduction, etc., to ensure safe operation of the device.
Small plug-in standby power supply developed by Changhong Battery is mainly used in mobile communications vehicles, active global positioning, time service and other systems, which has the characteristics of small in size, light weight, hot-plug etc. to makes it easy use, convenience, reliability.
The products of Changhong Battery conform to the requirements of GB4943, IEC60950, etc. in security and be in line with the requirements of YD / T731 in dielectric strength. In addition, Changhong Battery can supply innovative, customized non-standard products and solutions based on customers’ requirements to fully meet customers’ demand.
