1 model and principle

Information power supply and principle

Online working mode, high output stability, zero interruption time. Intelligent RS232 communication software monitoring. Support the kellong SNMP network adapter, effectively simplify network management and improve system reliability. Advanced power PFC control technology, AC input power factor > 0.98, reduce grid load, load green power concept, small size, high performance. The latest high frequency power conversion technology, small size, light weight, high reliability. Triple over-current protection and input over-voltage protection enhance the adaptability of UPS power supply and load impact resistance. UPS can judge the load three times and handle it intelligently to ensure the safe operation of equipment and UPS. Input state power protection: sensitive voltage sensing and unique switch to avoid high-voltage grid threatening the safety of equipment.

New energy and principles

It can detect AC voltage / current, DC voltage / current, current / cumulative generation, fault / status information battery management / protection, grid frequency, AC power, current / cumulative generation time. User friendly operation interface, convenient for management and operation. The perfect data processing ability can realize the function of time record, data or chart query. Adapt to system update and support remote software upgrade function.

Power supply and principle

It adopts high reliability and high efficiency power module, with two specifications of air cooling and natural air cooling, and the efficiency is more than 95%. Automatic management and protection of battery, automatic detection of terminal voltage, charge and discharge current of battery by time, control of uniform charge and floating charge of battery according to characteristics of battery, and set up audible and visual alarm for over / under voltage and over-current of battery. With the function of battery temperature compensation, the temperature compensation coefficient can be set according to different types of batteries, to meet the temperature compensation requirements of different brands of batteries, and to maximize the battery life. With powerful communication function, it is very convenient to connect with RTU device of substation or DCS of power plant, means and monitoring system. IEC (International Electrotechnical Commission), UL and other international standards are adopted in the system, so the reliability and safety are fully guaranteed. Hardware low differential autonomous current sharing technology: the maximum imbalance benefit of output current between parallel modules is less than ± 3%.
