YHZC series surge protector (Surge Protective Device, referred to as SPD) is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other devices in the circuit. Surges are generated from a wide range of sources, such as lightning induction, switch operation, electrostatic discharge, etc.

The normal self-discharge of a battery is due to the structural factors of the battery itself, such as impurities in the electrolyte, the presence of contaminants, or the partial detachment of active materials inside the battery, which settle at the bottom, causing the positive and negative plates to discharge through sedimentation. If a battery is not used for a long time, it will slowly discharge on its own; therefore, the car should be started periodically to charge the battery.

Maintenance of UPS (uninterruptible power supply) is essential to ensure its stable operation and extend its service life. The following are some main maintenance methods:

Learning how to calculate the size of an inverter based on your needs can be a tricky task, especially if you are not familiar with how inverters work or how much power they need to produce. Inverters are useful devices, but in order to make an accurate estimate or find the right answer, you may have the following questions about inverters.

Due to the unstable power quality, it often causes damage to computer hardware, system crashes, and loss of important data. Therefore, the Uninterruptible Power Supply (UPS) has gradually become an indispensable standard component when purchasing computer equipment. However, how to choose a UPS often troubles users, and an important part of a UPS power supply is the battery. To select a good UPS, one must choose a high-quality brand UPS battery.
