Digital Over and Under Voltage Protector

What is a Digital Over and Under Voltage Protector?

XENHO Factory’s Digital Over and Under Voltage Protector is a power safety device that integrates intelligent control with multiple protection features. It effectively addresses voltage instability issues caused by thunderstorms, power grid switching, or line faults. Equipped with a built-in LED digital display, the device provides a real-time, intuitive readout of the current voltage level, allowing users to constantly monitor their power supply environment. It supports an automatic delayed restart function, allowing users to customize a power restoration delay ranging from 30 seconds to 10 minutes; this prevents potential damage to equipment caused by frequent on-off cycling during voltage fluctuations. Furthermore, the device incorporates multiple protection mechanisms—including over-voltage, under-voltage, short-circuit, and overload protection—to ensure the stable operation of connected electrical equipment within complex power grid environments.

Customer Repurchase Rate

Thanks to its exceptional performance and reliable quality, this product has garnered widespread recognition in the market, maintaining a consistently high customer repurchase rate. Numerous users have reported that, following the installation of the Digital Over and Under Voltage Protector, the failure rate of their household appliances—specifically those caused by voltage fluctuations—has dropped significantly. This has effectively extended the service life of their appliances while saving on repair and replacement costs. Furthermore, its intelligent user interface and convenient delayed-restart function have received high praise from users, establishing it as the preferred protective device for both residential and industrial electrical safety.

Pallet Dimensions and Loading Configuration

1. The pallets measure 1200mm × 1000mm and utilize a standard pallet design. This configuration is compatible with a wide range of logistics, transportation, and warehousing systems, ensuring the stability and reliability of the products throughout the handling process.

2. Each pallet accommodates 40 Digital Over and Under Voltage Protectors. The units are arranged horizontally and stacked in layers, with shock-absorbing dividers inserted between each layer to effectively prevent friction and collision during transit.

3. The outer packaging consists of high-strength corrugated cardboard cartons, reinforced with corner protectors to significantly enhance compressive strength. This robust packaging is designed to withstand the rigors of long-distance sea freight and diverse climatic conditions, guaranteeing that the products remain safe and undamaged from the point of dispatch to final delivery.

Our Digital Over and Under Voltage Protectors have obtained certification under the International Electrotechnical Commission (IEC) standards and comply with the requirements of the RoHS environmental directive. With cumulative global shipments exceeding 500,000 units, these devices are widely deployed in power supply systems for smart homes, medical equipment, and precision instruments.
