１、超压、过压、欠压保护器不同一般普通电器，在可靠有效地保护被保护电器设备的同时必须要能自身保护，也就是220V突升到380V或440V的超高电压时保护器能立马跳闸保护且自身也保护了，不会损坏；不要忽略低电压时也要能保证正常工作；２、实时监控电网电压，超压、过压、欠压、浪涌、短路自动保护；３、输出电压范围可调，可根据不同电器的额定电压来设置输出电压值；４、合闸延时时间可调，可根据不同电器的特性来设置自动合闸的延时时间；５、380V超强自身保护，耐高压设计，安全更可靠，经久耐用；６、响应速度快，响应值精准，是更有效、更可靠的保证；７、自动恢复、人工合闸可切换，自动+手动，适用于各种场合，操作安全方便，设置为手动时停电再来电时不合闸，设置为自动时停电再来电时自动恢复合闸
1. Over-voltage, over-voltage and under-voltage protectors are different from ordinary electrical appliances. They must be able to protect themselves while reliably and effectively protecting the protected electrical appliances. That is to say, when 220V suddenly rises to 380V or 440V, the protector can trip immediately and protect itself without damage; do not neglect low voltage, but also ensure normal operation; 2. Real-time monitoring of power grid electricity; Voltage, overvoltage, undervoltage, surge, short-circuit automatic protection; 3. The range of output voltage can be adjusted, according to the rated voltage of different electrical appliances to set the output voltage value; 4. The closing delay time can be adjusted, according to the characteristics of different electrical appliances to set the automatic closing delay time; 5, 380V ultra-strong self-protection, high-voltage design, safe and more reliable, durable; Fast response speed and accurate response value are more effective and reliable guarantees; 7. Automatic recovery and manual closing can be switched on, automatic + manual, suitable for various occasions, safe and convenient operation, set as manual power outage and power outage when turn-on, set as automatic power outage and power outage when turn-on automatically restore closure.
