一、产品介绍

SRMUV系列欠电压监视继电器适用于发电机、变压器、变电线路的继电保护装置中，作为低电压闭锁的启动元件。(适用于交流50/60Hz)

继电器的设定值和滞后返回可以通过电位器无级调节。

SRMUV series of under-voltage superv***ry relays serve as startup components for under voltagelockoutin relay protection devices in generators, transformers, power transmission and transformationlines.(Are used in AC 50/60Hz)

The settings and lag and return times of the relay can be steplesslly adjusted with potentiometer.

触点容量ContactCapacity:在电压不大于250V时:触点长期接通电流为5A;在电压不大于250V时:电路时间常数L/R为5mS的

直流电路中，触点断开容量为50W;在电压不大于250V时:功率因数COS6为0.4的交流电路中，触点断开容量为250VA。

When the voltage is less than 250V, the continuous current o f the contacts is 5A; When the voltage is less than 250Vand time

constant L/R is 5mS inthe DC circuit, the switching capacity of the contacts is 50W;When the voltage is less than 250V and the

power factor COSpis 0.4 in the AC circuit, the switching capacity of the contacts is 250vA
