JSY-1 Type Voltage Loss Alarm RelayDetailed product description：

1. Application of JSY-1 type voltage loss alarm relay

Used as an alarm component in three-phase AC voltage systems when the voltage drops sharply.

2. Characteristics
2.1 It has three structural forms;
2.2 Can distinguish between single-phase voltage loss or three-phase voltage loss;
2.3 The dynamic contact points led out by the relay can be magnetically maintained after the action;
2.4 It has manual and external reset functions;
2.5 Export can be delayed according to user needs.

3. Main technical data of JSY-1 type voltage loss alarm relay:

Rated voltage V	Rated frequency Hz	Action voltage V	Action time in milliseconds	Power consumption		Return voltage V	Auxiliary voltage V
				DC (W)	Communicating VA/Xiang
one hundred (Phase voltage 58)	fifty	10% Rated voltage: ± 0.5	0.5 times When the action value is ≤ 30	seven	one	forty-eight	forty-eight
						one hundred and ten	one hundred and ten
						two hundred and twenty	two hundred and twenty
