Users buy a UPS power supply, the main purpose is what? High frequency, power frequency, interactive These are the direction of customer choice?
To avoid power failure due to uncertainties, resulting in hardware damage, and data loss.
UPS Chinese means "uninterruptible power supply", it can protect the computer system after the power failure to continue working for some time so that users can save an emergency, to avoid data loss. Personal computers generally do not need to configure, usually the company's server need to configure the UPS to prepare for power after the power can continue for some time to provide time to switch generator power generation. Interactive UPS is an intelligent UPS, can automatically detect whether the external input voltage is within the normal range, if the deviation can be boosted by the regulator circuit or buck, to provide a more stable sine wave output voltage. And it can communicate with the computer through the data interface (such as RS-232 serial port), through the monitoring software, the user can directly monitor the power from the computer screen and UPS status, simplify and facilitate the management work, and improve the computer system reliability. High-frequency UPS: the use of high-frequency switching technology to high-frequency switching components to replace the rectifier and inverter in the frequency transformer UPS, commonly known as high frequency machine, high frequency machine small size, high efficiency.
Power frequency UPS: the use of frequency transformers as rectifier and inverter components of the UPS commonly known as frequency machine, the main feature is the main power components stable and reliable, overload capacity and impact resistance
UPS power supply is uninterruptible power supply When the normal AC power supply interruption, the battery output DC into AC power supply equipment. Mainly for a single computer, computer network systems or other power electronic equipment to provide uninterrupted power supply. When the mains input is normal, UPS will be the main power supply after the supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine;
When the electricity interruption (accident power failure), UPS will immediately the battery power, through the inverter conversion method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS devices are usually protected against excessive voltage and low voltage.
