Product advantages
- Multi-channel AC power supply. When the main power supply fails, the standby power supply automatically starts running.
- Multiple high-frequency switch charging modules run in parallel, N+1 hot backup, high reliability;
- High frequency rectifier module, which can work independently in a single machine or in parallel with multiple modules, and can be used for online maintenance with electric plug and plug, convenient and fast
- Wide voltage input range, strong applicability of power grid, can be used in relatively harsh environment
- Intelligent control of charging module, smooth adjustment of output voltage and current; Independent flow equalizing, good stability and high precision
- The monitoring system adopts touch screen or large LCD Chinese characters display, friendly man-machine interface, intuitive and convenient operation
- You can set parameters for each part of the system through the monitoring module, which facilitates operation
- Open interface design, with powerful communication function, it is convenient to connect with substation RTU device, computer monitoring system, DCS
- The distributed monitoring system with microprocessor as the core is adopted to realize the telemetry, remote control, remote communication, remote adjustment and unattended of the power supply system
- Battery automatic management and protection, real-time automatic monitoring of battery terminal voltage, charge and discharge current and automatic control of battery equalization and floating charge conversion, battery overvoltage/undervoltage and overcurrent sound and light alarm and temperature automatic compensation functions. Ensure that the battery works in the best condition, prolong the battery life
N /A (Optional) DC/AC AC/DC system integration: In the case of an AC power failure, the storage battery provides continuous emergency AC/DC power for a long time
