Advantages: Double conversion. Sine output. Power factor.

Disadvantages: Nope Well, at least cut me - there are no flaws.

Comment: Received to us for a long time the desired equipment. And we have - problems with electricity. Well, how to protect the equipment is necessary. Chose a Powercom UPS with sinusoidal output. So that exactly everything was in order. I measured the output voltage myself. Smooth, at the time of switching to battery power no errors. The equipment has been working normally for three months, despite the abnormal behavior of the voltage on the network.

Advantages: Power factor 0.9. Double conversion. The output signal is in the form of a sinusoid. Wide input voltage range.

Disadvantages: The display is small in size.

Comment: One of the few professional bespereboynik, in which the setting of the functionality is simple, there is a screen for reading the most important information and there is active cooling. Possible to configure monitoring. To install and configure it - you need very, very little to have relevant knowledge. Pah-pah-pah, but so far it works without problems. And so - from the beginning of the year.

Advantages: Double conversion. 1800 watts of net power output. Imagine how much it can connect equipment ...
The width of the input voltage - 184-265 volts. In this interval, the UPS works and behaves absolutely adequately.
LCD screen. Small. With clear numbers of information on it.

Disadvantages: Nope

Comment: Hooray! We are overgrown with two new servers :) Things are sensible, powerful, awesome in terms of settings and capabilities :) For some reason, we didn’t even think about backup power when buying ... . Bought, hooked up. Began to customize. Nuuuuu, more convenient and clear settings, I have never met. I speak personally for myself, just that.

Advantages: Zero switching to autonomous operation. The moment of switching does not affect the equipment. Sinusoid. Active cooling in the form of a large built-in fan. Returns up to 92%.

Disadvantages: We do not see.

Comment: Long time working with us. And not a single time they wore not something to repair, they didn’t even send them for inspection. Terribly important and terribly expensive equipment is connected. Recently, the fault of our electricians was a serious power surge. A part of the people flew BPshniki in computers. And for us - everything works as it works.

Advantages: Double conversion - the computer and other equipment connected to the UPS, is protected from a variety of factors. This is for you and horse racing, and other problems in the network. UPS is online. EMI / RFI filters against electromagnetic interference.

Disadvantages: Those - did not notice.

Comment: We tried it on our mail server. There was only one problem - the UPS cannot be rack mounted. The server we crashed (hardware problems), while back and forth, ipshnik connected to your PC. How it works - it suits.
