Description
The unit works as a DC UPS: the rectifier supplies the load and at the same time keeps the storage battery on float charge, and when the mains disappears the load transfers to the battery without interruption. The thyristor circuit tolerates heavy duty well and has long been established in the power industry. The input is single-phase or three-phase with neutral, and the range is designated UC-1…UC-16. The standard output voltages of 24, 36, 48, 72, 110, 150, 220 and 400 V cover 24 V automation, 48 V communications, and 110 or 220 V substation operational current. Sealed lead-acid batteries are fitted, with NiCd, Li-Ion or NaNiCl2 on request. The IP20 enclosure is intended for electrical rooms and relay halls.
How to choose
The output voltage is set by the load: for substation relay protection it is usually 110 or 220 V, for automation 24 V, for communications 48 V. Power is calculated as the sum of the constant load and the battery charging current, so the rectifier is taken with a margin. If consumers need AC, look at the Futura online UPS of 5–800 kVA or Mizar of 2–10 kVA.
