THM for a clean UPS
The THM concept (Total Harmonic Management) offers a number of high-performance solutions to control harmonics downstream and upstream of the UPS:
-
downstream, for 100% non-linear loads, the Galaxy PW distortion level never exceeds 3%, even for highly distorting non-linear loads with crest factors up to 3:1. Galaxy PW efficiency remains unaffected even with loads of this type,
-
upstream, Galaxy PW can be equipped with a THM active filter, reducing harmonic distortion to less than 3%. This solution is based on SineWave[TM] harmonic conditioning technology, offering unsurpassed performance. In this way, Galaxy PW delivers clean power to the load and causes no electrical disturbances upstream.

Battery Monitor
When you need your UPS the most, its performance depends on the state of the batteries. That is why Galaxy PW comes with the most effective battery monitoring system available on the market.
Battery Monitor™ offers the following features to optimize battery life and maximize the security of your installation:
-
measurement of true backup time, taking into account the age of the battery and the temperature,
-
prediction of remaining battery life,
-
protection against excessive discharge,
-
regulation of battery charge voltage as a function of temperature,
-
battery current limiting,
-
automatic battery tests at regular intervals.
High efficiency plus intelligent Eco mode
Galaxy PW UPSs offer efficiencies as high as 93.5%. And for even greater energy savings, you can run them in intelligent Eco mode for less sensitive loads (e.g. lighting).
In intelligent Eco mode, the UPS supplies your applications via the static bypass, returning immediately to on-line double conversion if the need arises. In this way, you get efficiency levels as high as 97% when the AC input source is within acceptable tolerances. This can mean annual energy savings of up to 8% of the cost of your UPS.
