II. Application

Auto Recovery Over Voltage And Under Voltage Protective Device for solar is an automatic protector with over voltage and under voltage protection relay. When the voltage rises over 285V or decreases under 150V, 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 265V or the voltage rises back to 175V, 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.

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
