APC by Schneider Electric Smart-UPS RT 10000VA 230V

Advantages: Summarizes 3 phases in one!

Disadvantages: The price is space. Noisy.

Comment: For many, this is simply a sophisticated and powerful uninterruptible power supply, but for me the power supply at the input turned out to be 3 phases, and at the output 1 phase. The result was an analogue of a balancing transformer, but without side properties in the form of giant inrush currents. The power of the three phases is summed into one, which is sometimes very necessary.

Advantages: APC as it is. Quite honest.
Ergonomics, convenience, 4 easily-detachable units of 8 batteries 12V 5Ah, work from 1-and 3-phase lines

Disadvantages: With regular work at a maximum, the bottom batteries are still swollen. Probably overheating. For the discharge and freezing was not.
Input circuit protection on L1 only. L2 and L3 three-phase current without automatic circuit breaker

Comment: The APC's "Legendary Reliability" sucks in Russia
For we have put on a three-phase input in the building some kind of shnyaga, which, when turned on / off, creates a drop / cast in one phase relative to the others .... and this is more than 15% of the UAC difference
In general, he still snapped good-bye and emitted a magical white smoke ... we are looking for a replacement. Three SU RT 5000 is quite an alternative.
By the way, who dead APC SU RT 10000?

Advantages: Quality goods. Long battery life (directly dependent on the load). Battery life is 3-5 years, depending on operating conditions.

Disadvantages: Price is the only downside.

Comment: With proper operation will work for a very long time. Only once in 6 months it is necessary to do some maintenance and once in 3-5 years to change the batteries, there are only 4 of them. When disconnecting the external network 220W, a fully charged UPS with a load of ~ 10 servers holds about 15 minutes. In this case, the load is of the order of 40%, i.e. The stock of the UPS is very large.
