Description
The unit is meant for cases where a voltage sag disrupts production or airfield lighting equipment. Reaction starts after 140 µs and compensation takes less than 3 ms, so the time a sag acts on the load shrinks to milliseconds. The output voltage stays within ±0.2 %. For a single-phase sag the data give down to 45 % Un for 30 s and down to 0 % for 10 s. The rated voltage is 400 V, with 208 and 690 V versions built on request; the mains frequency is 50/60 Hz. The IP20 degree of protection assumes installation indoors.
How to choose
The main selection parameters are the power of 300–1800 kVA and the 400 V voltage, while 208 and 690 V networks are served on request. Sag depth is judged from the single-phase sag data, down to 45 % Un for 30 s and down to 0 % for 10 s. If the trouble is harmonics rather than sags, look at the AHF active filters for 50–150 A or the PHF passive filters for 5–750 A.
