The UPS is in use now. We did a test after receiving it. Equipped with the compatible battery, it could continue to supply the rack for about 10 minutes when we shut down the power. In the last month, we went through blackout for twice, and the UPS could do seamless power conversion. That was very good.

Good quality. Power supply is stable. So far we have not met any problems with either the customer service or this UPS. And we expect it will keep the good performance in the future.
