What are the specific functions of a UPS host?

UPS (Uninterruptible Power System/Uninterruptible Power Supply), that is, uninterruptible power supply, is a system device that connects the battery (mostly lead-acid maintenance-free battery) to the host and converts DC power into mains power through module circuits such as the host inverter.

.

It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc.

When the mains power input is normal, the UPS stabilizes the mains power and supplies it to the load. At this time, the UPS is an AC voltage stabilizer, and it also charges the internal battery; when the mains power is interrupted (accidental power outage)

At this time, the UPS immediately continues to supply 220V AC power to the load through the inverter switching and conversion method from the battery's DC power, so that the load can maintain normal operation and protect the load software and hardware from damage.

UPS equipment usually provides protection against overvoltage or undervoltage.

Extended information: UPS and DC power supply are important power supply guarantee equipment for enterprises. Traditional maintenance management includes: 1. Daily inspection of appearance, regular replacement of wearing parts such as batteries, filter capacitors, fans, etc., and battery activation during overhaul; 2.

Modify or adopt replacement equipment and use advanced tools to test battery performance.

This management method has high investment costs for enterprises, a heavy workload for maintenance personnel, it is difficult to grasp the equipment operating status and key data in real time, and the ability to prevent equipment accidents is low.

Implementing online maintenance management can avoid the shortcomings of traditional methods and obtain good benefits.
