NOV-40 self resetting overvoltage and undervoltage protector NOV-40 na mag-reset sa pagkamataas o pagkamababa ng kuryente

Ang NOV type self resetting overvoltage and undervoltage protector usa nga intelligent distribution protection device, nga naglakip og core function sa pag-monitor sa line voltage. Kapag ang voltage nagsobra sa safe range (undervoltage 140V-210V, overvoltage 230V-300V), ang power mahimo nga matapos sa 0.5 seconds; human sa voltage mobalik normal, maauotog balik ang reconnect human sa preset delay (adjustable gikan 1-600 seconds) walay kinahanglanon og manual intervention sulod sa buhatan. Ang iyang IP20 protection level naa sa installation requirements sa conventional distribution boxes.

Advantages of NOV type self resetting overvoltage and undervoltage protector:
1. Accurate protection: May error range ± 2%, ang protection action accurate ug reliable.
2. Quick response: Ang delay sa overvoltage ug undervoltage action kini 0.5 seconds, quick cutting off sa dangerous power supply.
3. Flexible self recovery: Adjustable reset time 1-600 seconds, suitable for different device restart needs.
4. Durable and long-lasting: up to 100000 electrical cycles ug 1 million mechanical cycles, with stability.
5. Wide compatibility: Suitable for AC 220V/50-60Hz power grid, with strong applicability.
Product features of NOV type self resetting overvoltage and undervoltage protector:
1. Wide threshold protection:
Undervoltage protection covers 140V hangtod 210V, while overvoltage protection covers 230V hangtod 300V, effectively responding to various voltage abnormal scenarios.
2. High precision monitoring:
± 2% error control, accurate voltage judgment, avoiding misoperation or leakage protection.
3. Quick response mechanism:
After detecting abnormal voltage, it only takes 0.5 seconds to complete the power-off action, reducing the risk of equipment damage.
4. Intelligent reset:
Provide flexible reset delay settings ranging from 1 second to 600 seconds to meet the safe restart interval requirements of various electrical appliances such as air conditioners and refrigerator compressors.
5. Double long-life design:
The electrical components have a breaking life of 100000 times, and the mechanical structure supports up to 1 million operations, ensuring long-term stable operation.
6. Standard protection:
IP20 shell protection effectively prevents large solid foreign objects from entering, suitable for installation in standard distribution box environments.
