名称：双显过欠压保护器 adjustable voltage protector

■ 用途 Purpose

多功能自复式双显保护器集过压保护，欠压保护，过流保护与一体的综合智能保 护器，当线路中出现过压，欠压及过流故障时，本产品能瞬间切断电路，避免电气设备造成不必要的损坏。当电路恢复正常时保护器能自动恢复电路使用电气设备正常工 作，本产品的过压值，欠压值，过流值，电路恢复时间值及过流保护复位时间值值均 可自行设定，可根据当地实际情况及电气使用条件进行相应参数调整。
Multifunctional self resetting double display protector is a comprehensive intelligent protector integrating overvoltage protection, undervoltage protection and overcurrent protection. When overvoltage, undervoltage and overcurrent faults occur in the line, this product can instantly cut off the circuit to avoid unnecessary damage to electrical equipment. When the circuit returns to normal, the protector can automatically restore the normal operation of the electrical equipment used in the circuit. The overvoltage value, undervoltage value, overcurrent value, circuit recovery time value and overcurrent protection reset time value of this product can be set by themselves, and the corresponding parameters can be adjusted according to the local actual situation and electrical conditions.

■ 产品特点 Product features

产品完全符合企业标准生产的单相自复式重合闸保护器；

当线路发生过压，欠压及过流故障时本产品自动切断线路，当线路电压或电流恢复 正常时本产品按用户设定的延时时间后自动恢复正常供电，线路出现瞬间或暂态过压时保护器不产生误动作。

线路因某种因素造成电压不稳或突然断电再来电状态时本产品不马上接通电源，此延时时间由用户自行按当地情况而设置。

线路电压在最高时不应高与330VAC以防止产品自身由于电源电压过高而损坏，如 有特定场合需要高电源与厂家联系。

The product fully conforms to the enterprise standard and produces single-phase self resetting reclosing protector;
When the line has overvoltage, undervoltage and overcurrent faults, the product will automatically cut off the line. When the line voltage or current returns to normal, the product will automatically restore the normal power supply according to the delay time set by the user. When the line has instantaneous or transient overvoltage, the protector will not misoperate.
When the voltage of the line is unstable or suddenly powered off and then called due to some factor, the product will not be powered on immediately. This delay time is set by the user according to the local situation.
The line voltage should not be higher than 330vac at the maximum to prevent the product from being damaged due to the high power supply voltage. If there is a need for high power supply in specific occasions, contact the manufacturer.
