The high system availability of high frequency UPS

If UPS redundancy above two UPS modules, the availability of UPS up to 99.999%, MTBF (Mean Time Between Failure) up to more than 15 million hours.
Minimum downtime. If the number of faulty UPS modules is less than or equal to the number of redundant UPS modules, the UPS module can be replaced online without affecting the operation of other modules; If the number of faulty UPS modules is greater than the number of redundant UPS modules, due to the use of replacement UPS module maintenance, so downtime will not exceed 5 minutes.
