Voltage alarm (model: DY), also known as voltage monitoring device, will immediately sound the horn when it detects that the voltage exceeds the upper limit alarm value, falls below the lower limit alarm value, or exceeds the set interval alarm value between the upper and lower limits. The voltage measurement and control device will output a switch signal, which is suitable for monitoring voltage changes in power companies, telecommunications companies, distribution rooms, etc., to prevent accidents caused by abnormal voltage. It can also be used for anti-theft alarm of power cables.

Welcome to choose the horn flashing voltage alarm (model: DY-MS, factory price: 335 yuan/set).

Welcome to choose the switch output voltage measurement and control instrument (model: DYK, factory price: 255 yuan/unit).

1. Alarm method: When the voltage exceeds the upper limit alarm value, falls below the lower limit alarm value, or exceeds the set interval alarm value between the upper and lower limits, the voltage alarm will immediately sound the horn and the voltage measurement and control instrument will output a switch value.

2. Voltage alarm:

① Monitoring voltage: DC－100～500V、DC－20～100V、DC－2～10V、DC－0.2～1V，AC 0～500V、AC 0～100V、AC 0～10V、AC 0～1V。 When monitoring higher voltages, voltage transformers with corresponding ratios can be used.

② Measurement accuracy: 0.001.

③ Communication frequency response: 40-400Hz.

④ Setting content: upper limit alarm value, upper limit alarm reset value, lower limit alarm value, lower limit alarm reset value, etc.

⑤ Memory function: After the mains power is cut off, the saved settings will not be lost, and it can work as usual when there is a call.

⑥ Relay contact capacity: ≤ 3A.

⑦ Alarm volume: ≤ 100 decibels.

3. Horn flash (optional):

① Alarm volume: ≤ 115 decibels.

② Flash frequency: about 100 times per minute.

4. Working voltage: Voltage alarm AC220V, horn flash DC12V/220V power adapter.

5. Working current: Voltage alarm standby ≤ 80mA, alarm ≤ 150mA, horn flash ≤ 300mA.

6. Working environment: temperature -30 ℃~+60 ℃, relative humidity ≤ 85% RH.
