What is the importance of over-voltage and under-voltage protectors?
One day, the equipment supervisor from the neighboring factory rushed into our technical department, sweating profusely and speaking in an anxious tone. His electronics parts factory was undergoing power grid maintenance that day when the voltage suddenly surged to 380V. Without over-voltage and under-voltage protectors installed, three production lines ground to a halt instantly. The motherboards of several imported machine tools were directly damaged, with preliminary losses estimated to exceed 200,000 yuan.
Faced with the same voltage fluctuation, the over-voltage and under-voltage protectors in our workshop tripped accurately within 0.1 seconds, cutting off the abnormal power supply in a timely manner and leaving all equipment intact. Once the voltage stabilized, the protectors automatically reset, enabling the production lines to restart seamlessly without any downtime.
In what aspects do the functions and protection of over-voltage and under-voltage protectors?
Voltage fluctuations in the power grid are far more frequent than we might imagine. Peak power consumption hours, aging circuits, emergency maintenance, and even thunderstorms can all trigger over-voltage or under-voltage issues. Under-voltage forces motor-driven equipment to operate under overload conditions, causing coils to overheat and burn out. Over-voltage, on the other hand, directly damages electrical components, resulting in irreversible failures. For factories, commercial establishments, and office buildings, a single voltage anomaly not only incurs equipment repair costs, but also triggers a cascade of losses such as production halts, order delays, and merchandise spoilage.
An over-voltage and under-voltage protector acts as an intelligent safety sentinel for electrical circuits. It monitors voltage levels 24/7 in real time. Upon detecting voltage beyond the safe threshold, it cuts off the power supply within milliseconds, eliminating voltage-related risks at the source. When voltage returns to normal parameters, it can reset either automatically or manually, ensuring uninterrupted power supply. Unlike traditional fuses and air switches, it specializes in countering the "invisible threat" of voltage anomalies, filling the gaps in conventional protection devices and truly achieving prevention before incidents occur.
Our products stand out as the preferred choice for numerous enterprises, backed by three core advantages:
1. Precision Monitoring: It delivers voltage detection accuracy of ±1V and a response speed of 0.1 seconds, capturing even the slightest voltage irregularities without fail.
2. Durable & Safe: Featuring a flame-retardant casing and surge protection design, our products hold national 3C certification, ensuring reliable performance in complex power environments with an extended service life.
3. Customizable Compatibility: Available in three series for household, commercial, and industrial applications, we offer tailored parameter customization to meet protection requirements across diverse scenarios.
In summary
Electrical safety allows no room for luck. A compact over-voltage and under-voltage protector requires a modest investment, yet it safeguards your production lifeline and property security effectively.
Choose PEOPLE, and let professional protection secure your power supply with peace of mind.
