UPS（Uninterruptible Power System ）， Uninterruptible power supply is a constant voltage and constant frequency uninterruptible power supply that includes energy storage devices and an inverter as the main component. Mainly used to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load for use. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the internal battery; When the mains power is interrupted (accident power outage), UPS immediately supplies 220V AC power from the internal battery to the load through inverter conversion, ensuring normal operation of the load and protecting its software and hardware from damage. UPS equipment typically provides protection against both high and low voltage.

The YH-UP86 series (single in single out/three in single out) dual conversion online UPS has a beautiful appearance, greatly improving product performance and reliability. It effectively solves power outages, high or low mains voltage, voltage drops or oscillations, high voltage pulses, voltage fluctuations, surge voltages, harmonic distortion, clutter interference, frequency fluctuations, and greatly improves its performance in reliability, efficiency, adaptability, and flexibility, fully meeting users' needs for stable and uninterrupted power. At the same time, its rich and scalable features also provide personalized solutions to meet users' needs.
