UPS (Uninterruptible Power System/Uninterruptible Power Supply), that is, uninterruptible power supply, is the battery (mostly lead-acid maintenance-free batteries) connected to the host, through the host inverter and other modular circuits will be converted to DC power utility system equipment.
The uninterruptible power supply is mainly used to provide stable and uninterrupted power supply for a single computer, computer network system or power electronic equipment such as solenoid valves and pressure transmitters. When the utility power input is normal, the UPS stabilizes and supplies power to the load. Voltage. At this time, the ups is an AC voltage regulator which also charges the batteries in the machine. When the city power outage (accidental blackout), the ups will be converted to continue to provide 220vac through the inverter power supply, and immediately provide battery DC power to the load, the current to maintain the load normal work, to protect the load hardware and software from damage. Uninterruptible power supply equipment usually provide high voltage or low voltage protection.
Expanded Information:
Ups and DC power supplies are important power supply equipment for businesses. Traditional maintenance management includes:
1, daily appearance inspection, regular replacement of batteries, filter capacitors, fans and other wearing parts, maintenance start battery, etc..
2. Modifying or using replacement equipment, and using advanced tools to test battery performance. This management mode is characterized by high investment costs, heavy workload of maintenance personnel, difficulty in grasping the real-time operating status of equipment and key data, and low ability to prevent equipment accidents. The implementation of online maintenance management can avoid the shortcomings of traditional methods and obtain good benefits.
