UPS means uninterruptible power supply that contains energy storage devices. It is mainly used to provide uninterrupted power supply to some equipment which requires high stability of power supply.
The uninterruptible power supply is the system equipment that connects the battery (mostly lead-acid maintenance-free battery) with the host and converts the direct current into mains electricity through the host inverter and other module circuits. It is mainly used to provide a 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 input is normal, ups supplies the mains voltage regulator to the load. At this time, UPS is an alternating current voltage regulator, and it also charges the battery inside the machine. When the mains is interrupted (accidental power failure), the ups will immediately supply 220V AC power to the load by switching the dc power of the battery through the method of inverter conversion, so that the load can maintain normal work and protect the software and hardware of the load from damage. Its equipment usually provides protection against high or low voltage. Uninterruptible power supply is widely used in industry, hospital, network equipment, data storage equipment, transportation and other fields. It can also be used for home use, such as 600W ups inverter to charge mobile phones and computers.
Precautions for Use:
- Ensure that the UPS installation environment is free from direct sunlight and has sufficient ventilation space. Ensure that the temperature of the ups installation environment is not higher than 25 ℃. If the operating environment temperature exceeds 25 ℃, the battery life is shortened by about half for every 10 ℃ increase in temperature.
- High power thyristor load, thyristor bridge rectifier or half wave rectifier load shall not be used at the output end of uninterruptible power supply. This kind of load is easy to cause the final drive transistor of inverter to be burned.
- Strictly follow the correct startup and shutdown sequence to prevent the ups power supply voltage output from fluctuating due to sudden load increase or decrease.
- Do not turn off or on the ups power frequently. After turning off the ups power, wait at least 30 seconds before turning on the ups power.
- Maintain the uninterruptible power supply periodically, such as observing the indicator status, removing dust, measuring battery voltage, replacing unqualified batteries, checking the running status of fans, and monitoring and adjusting ups system parameters.
