230V auto recovery over and under voltage protection device with automatic protective relay preventing disconnection of null line

230V auto recovery over and under voltage protection device with automatic protective relay preventing disconnection of null line

I.Function:

1. Under voltage protection 170V

2. Over voltage protection 270V

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

4. Preventing disconnection of null line, when null line disconnect or break, the protector will work to cut off the circuit to protect the appliances.

Rated voltage: 380V; Frequency: 50Hz

II. Application

Auto Recovery Over Voltage And Under Voltage Protective Device is an automatic protector with over voltage and under voltage protection relay. 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. Besides, iQG series protector can prevent disconnection of null line. When null line is disconnected or cut off, the protector will work to cut off the circuit to protect the appliances.

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
