变频器特点
1.采用DSP控制，DIV系列变频器是智能型产品，具有良好的设计和可靠性。
2. DIV系列变频器采用SPWM技术，输出稳定的电压和频率，纯正弦波。
3. DIV系列变频器具有良好的兼容性，内置旁路开关，高过载特性，可靠连续供电。
4. DIV系列变频器可以采用交流电源式和直流电源式：
交流电源类型是指城市电力正常，城市电力关闭，变频器进入工作状态时，城市供电是主要的。
直流电源类型是指城市电力正常时变频器电源为主，变频器电源关闭时，市电自动进入工作状态。
5.采用优异的设计，DIV系列变频器可以在运行状态下自动切换到旁路，易于维护和更换电池，而不影响负载电源。
6.如果电池电压过高或过低，过载报警停机输出，当电池电压恢复正常时，电池电压恢复;电源输出在过载后50秒内自动恢复。该功能非常适合没有值班人员的通讯台。
7.DIV系列变频器可以支持网络通讯系统，电源工作状态可由监控软件进行监控。
8. DIV系列变频器提供两个干式连接器，可用于直流输入故障检查和交流输出问题警告。

Features of Inverter
1. With DSP control, DIV Series inverter is an intelligence model product, good designing and reliability are the advantages.
2. DIV series inverter is adopting SPWM technology, with the output of stabilized voltage and frequency, pure sine-wave.
3. DIV series inverter has good compatibility, built-in by-pass switch, high overload feature for reliable and continuous power supply.
4. DIV series inverter can be AC power type and DC power type:
AC power type means the city power supply is main when the city power is normal, when city power is off, inverter comes into work state.
DC power type means the inverter power supply is main when the city power is normal, when inverter power is off, city power comes into work state automatically.
5. With the excellent designing, DIV series inverter can be auto switched to bypass on the running state, it's easy to maintain and replace the battery without effecting load power supply.
6. In case there is battery voltage high/low or overload, the overload warning shutdown output, when battery voltage recovers normal, battery voltage recovers; Power supply output will auto recovers in 50 seconds after overload off. This function is very suitable for the communication station in which there is no person on duty.
7. DIV series inverter can support network communication system, power working state can be monitored by the supervision software.
8. DIV series inverter provides with two dry connectors which can be used for DC input fault checking and AC output problem warning.
