Solar Auto Recovery Over Voltage And Under Voltage Protective Device Single Phase and Three Phase 2P 4P 40A 63A 100A for solar projects anti-islanding

I.Function:

1. Under voltage protection 2P: 150V(Single Phase) 4P: 250V (Three Phase)

2. Over voltage protection 2P: 285V (Single Phase) 4P: 475V (Three Phase)

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

Rated voltage: 230V; Frequency: 50Hz

II. Application

Solar Auto Recovery Over Voltage And Under Voltage Protective Device is an automatic protector with over voltage and under voltage protection relay. It is specially designed for solar project and solar installation. It can well protect the solar power station, when the voltage rises over 285V or decreases under 150V in single phase,(Or the voltage rises over 475V or decreases under 250V in Three phase), 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.

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
