230V auto recovery over and under voltage protection device with automatic reconnect protective relay with voltmeter showing real time voltage

HC Electric Auto Recovery Over and Under Voltage Protection Device With Voltmeter showing real time voltage

I. Function:

1. Under voltage protection 175V

2. Over voltage protection 275V

3. Delay on Reconnect time (delay on time): 30-60s        

4. Voltmeter: Detecting real time voltage on the screen     

Rated voltage: 230V; Frequency: 50Hz 

II. Application

Auto Recovery Over Voltage And Under Voltage Protective Device with Voltmeter is an automatic protector with over voltage and under voltage protection relay which can also show the real time voltage on the screen . When the voltage rises over 275V or decreases under 175V, this product can immediately cut off the power to prevent household electrical appliances from being destroyed by fluctuation of voltage. When the voltage drops back to 255V or the voltage rises back to 185V, after about 30 seconds delay,the device will reconnect to bring power back which acts like an automatic circuit breaker with over and under voltage function. Also the real time voltage can be detected on the screen. 

III. HC Electric Advantages

1. We manufacture the key component: Magnetic Latching Relay

2. We use 10K Varistor,Can absorb lightning surge and circuit surge current, if the varistor is not installed, the components will be destroyed.

3. Voltage Reduction Safety Standard Capacitor: Specially customized

4. Imported LM224 Chip. Make sure the device can work between -40℃ and +85℃

5. Circuit Board Conformal Coating(Salt-spray resistant,Waterproof,Anti Mildew)

6. Silver Contact Area 10% bigger than Other brand

7. -40-85℃ Testing Environment

8. Single Phase 440V Voltage Critical Testing
