1、 Power grid fluctuations strike, equipment 'lying down', who will save it?

Have you ever encountered these bad things:

The chiller unit running vigorously in the workshop suddenly stopped due to a sudden surge in grid voltage; The air conditioning in the shopping mall frequently reports errors, and surprisingly, the compressor is damaged due to low voltage; The computer room that was on duty late at night suddenly shut down due to unstable voltage, and precious data was almost lost

In industrial production and commercial operation, voltage fluctuations in the power grid are like an "invisible killer" - factors such as lightning strikes, sudden changes in peak load, and line aging can all cause overvoltage and undervoltage faults. Traditional solutions either rely on manual closing, which not only delays production but may also cause irreversible damage to equipment due to untimely operation; Either use a regular protector with a fixed threshold that cannot adapt to different device requirements, and the protection effect will be greatly reduced.

2、 Intelligent Guardian "launched: automatic protection+precise adaptation, worry free and reliable

As the core protection equipment specially designed by Ankerui for low-voltage distribution scenarios, the ASJ10-GQ series self resetting overvoltage and undervoltage protector is like a "smart electrician" on duty 24 hours a day, guarding equipment safety with three core advantages:

1. Self recovery function, no need for manual "firefighting"

When the power grid voltage is abnormal, the protector will respond in milliseconds and automatically disconnect the load circuit to prevent equipment from being damaged by overvoltage breakdown or undervoltage burnout; After the voltage returns to normal, there is no need for manual operation. The equipment will automatically close after a delay of about 30 seconds, quickly restoring power supply. Whether it is an unmanned computer room or a continuous production workshop, "automatic fault isolation and automatic resumption of work" can be achieved, greatly reducing downtime losses.

2. Adjustable threshold, suitable for all scene requirements

Unlike the limitations of traditional protectors with fixed thresholds, the ASJ10-GQ series supports precise adjustment of overvoltage and undervoltage thresholds: the overvoltage action value can be customized between 275~456V, and the undervoltage action value can be flexibly set between 187~323V. Whether it's 380V industrial motors, 220V commercial lighting, precision instruments, or new energy equipment, we can tailor protection solutions based on the voltage tolerance range of the equipment to avoid false triggering or insufficient protection.

3. Three phase/single-phase full coverage, easy installation without occupying space

The series of products covers various pole numbers such as 1P, 2P, 3P, and 4P, which can adapt to single-phase 220V household and commercial scenarios, as well as meet the protection needs of three-phase 380V industrial equipment such as chillers, water pumps, and fans. Installed with 35mm standard guide rails, it is compact in size and can be directly embedded into distribution cabinets/boxes without the need for additional openings. Installation and wiring can be completed in 10 minutes, making it easy to adapt to both new and old distribution systems.

In addition, the product also has functions such as overload protection and voltage abnormality indication, paired with clear status indicator lights, making the equipment's operating status clear at a glance, and operation and maintenance personnel can quickly troubleshoot problems without the need for professional tools.

3、 From the workshop to the mall, full scene protection is visible

At a certain automotive parts factory, the stamping equipment in the workshop frequently malfunctions due to power grid fluctuations, resulting in a monthly loss of nearly 10000 yuan. After installing ASJ10-GQ-3P-63, the equipment automatically shuts off protection in case of abnormal voltage, and quickly closes after recovery. There has not been a single shutdown caused by voltage issues to date;

The cold chain system of a certain chain supermarket once caused the freezer to shut down due to low voltage at night, resulting in severe losses due to food spoilage. After selecting ASJ10-GQ-2P-40, the undervoltage protection threshold is accurately set, and the refrigerator continues to operate stably, solving the worry of voltage fluctuations;

From the power circuit of industrial production, to the distribution system of commercial buildings, and to the end power supply of residential areas, the Ankrui ASJ10-GQ series self resetting overvoltage and undervoltage protector has become a "power safety barrier" for millions of users with stable performance and flexible adaptability.

4、 Choosing the right protective equipment means buying "insurance" for the device

Electricity safety is no small matter, a voltage fluctuation can cause tens of thousands of yuan in equipment damage. As a company that has been deeply involved in the field of energy IoT for many years, Ankrui's ASJ10-GQ series products have passed rigorous quality testing and have advantages such as strong overload capacity, long service life, and good anti-interference ability. They can not only effectively resist power grid fluctuations, but also reduce equipment operation and maintenance costs and extend equipment service life.

Whether it's power distribution support for new projects or upgrading old systems, choosing the Ankerui ASJ10-GQ series self resetting overvoltage and undervoltage protector is a worry free, reassuring, and reassuring choice. Let professional equipment safeguard electrical safety, allowing you to focus on core business without any worries!
