Product details:

1.Product Overview
An overvoltage and undervoltage protector is an electrical protection device used to protect electrical equipment from the effects of overvoltage or undervoltage. Voltage anomalies are a common problem in power systems, which may be caused by fluctuations in the power grid, equipment failures, or natural disasters such as lightning. Excessive or insufficient voltage can cause damage to electrical equipment, affecting its normal operation and even leading to equipment damage. The design of this protector can automatically detect voltage fluctuations and quickly cut off power or issue warnings in case of abnormal voltage, ensuring that the equipment operates within a safe voltage range and preventing equipment damage.
2.Main features
Overvoltage protection:
When the voltage exceeds the set safe range, the overvoltage protector will promptly cut off the power supply to prevent equipment from being damaged by excessive voltage. Usually, devices have a set value that automatically shuts off when exceeded to avoid damage to the device.
Undervoltage protection:
If the voltage drops below the set safe range, the undervoltage protector will automatically disconnect the power supply to prevent the equipment from malfunctioning or malfunctioning due to low voltage. Long term low voltage operation may cause equipment to heat up, decrease efficiency, or even burn out.
Automatic recovery function:
Many modern overvoltage and undervoltage protectors have automatic recovery functions. Once the voltage returns to the normal range, the protector will automatically reconnect the power supply and the device will continue to operate normally. This feature reduces manual intervention and improves the automation management of equipment.
Multiple voltage settings:
The product usually supports multiple voltage settings, and users can adjust the threshold of overvoltage and undervoltage according to their actual needs. By setting appropriate thresholds, it is possible to ensure effective protection of devices in different power environments.
Real time monitoring:
Modern protectors also have real-time monitoring capabilities, which can monitor voltage conditions through display screens or external devices. In this way, users can always monitor voltage fluctuations in the power grid and prevent voltage anomalies in advance.
High precision protection:
This protector adopts high-precision voltage detection technology, which can accurately identify voltage fluctuations and ensure that the power supply is cut off in a timely manner before the voltage reaches the level that endangers the equipment, avoiding unnecessary damage.
Overload and short circuit protection:
In addition to overvoltage and undervoltage protection, many products also have overload and short circuit protection functions. When the system experiences overload or short circuit, the equipment will automatically power off, protecting electrical equipment and circuits from damage.
3.Application scenarios
Household appliance protection:
Electrical appliances in households, such as air conditioners, televisions, refrigerators, etc., often face voltage fluctuations. By installing overvoltage and undervoltage protectors, equipment damage caused by voltage fluctuations can be avoided, and the service life of household appliances can be extended.
Industrial equipment protection:
In the industrial production process, many high-value equipment such as CNC machine tools, robots, transmission equipment, etc. are very sensitive to voltage. Overvoltage and undervoltage protectors can effectively protect these devices from voltage anomalies, reduce production downtime, and ensure production stability.
Commercial equipment protection:
The power system in commercial places is often connected to a large number of electronic devices and lighting systems, and voltage fluctuations may cause system failures, affecting normal operations. By using overvoltage and undervoltage protectors, unnecessary electrical accidents can be avoided and the safe operation of equipment can be ensured.
Data center and computer equipment:
The servers and other computer equipment in data centers are particularly sensitive to voltage anomalies. Overvoltage and undervoltage protectors can promptly identify voltage fluctuations and ensure that equipment is at a safe operating voltage, preventing data loss or equipment damage.
Power system protection:
In some power systems, overvoltage and undervoltage protectors are key protective devices that can ensure that power equipment (such as transformers, generators, etc.) are not affected by voltage fluctuations and ensure the stability of the power grid system.
4.Technical specifications
Rated working voltage: It usually supports common voltage specifications such as 220V and 380V, and can be selected according to user needs.
Voltage detection range: The adjustable overvoltage and undervoltage protection range is usually ± 10% to ± 20% (depending on the model).
Response time: Usually responds within a few tens of milliseconds, and immediately activates protection when voltage fluctuations exceed the set range.
Recovery time: usually a few seconds, when the voltage returns to the normal range, the protector will automatically resume operation.
Overload protection: With overload protection function, it can deal with power-off protection when the current is too high.
Working temperature range: -10 ℃ to 50 ℃, suitable for various environmental conditions.
Display function: Some models are equipped with LCD or LED display screens, which can display real-time voltage, alarm information, etc.
5.Product advantages
Effective prevention of equipment damage: By monitoring voltage changes in real-time and cutting off power in a timely manner, long-term damage to electrical equipment caused by overvoltage and undervoltage can be prevented.
Extend the service life of equipment: Protectors can effectively reduce the impact of voltage fluctuations on equipment, thereby extending its service life and reducing maintenance costs.
Automated protection: Equipped with automatic recovery function, it can automatically turn on the power when the voltage returns to normal, reducing manual intervention and improving work efficiency.
Adapt to various power environments: The threshold for overvoltage and undervoltage can be adjusted according to different devices and usage environments, with a wide range of applications.
Energy saving and environmental protection: After the protector cuts off the power supply, it can effectively prevent equipment from wasting electricity when the voltage is abnormal, reduce energy consumption, and minimize losses.

Summary:

Overvoltage and undervoltage protector is an important electrical protection device widely used in fields such as homes, industries, businesses, and data centers. It effectively protects electrical equipment from damage caused by overvoltage and undervoltage by monitoring voltage fluctuations in real time and cutting off the power supply in case of abnormal voltage, ensuring the normal operation of the equipment. With automatic recovery function and high-precision protection characteristics, it can extend the service life of equipment, improve system stability, and is one of the indispensable devices in modern power protection.
