DC-UPS - CBI Series

This is a revolutionary line, designed to provide uninterruptible power whatever condition the system is in, by means of sophisticated and completely automatic management of any type of industrial battery. Easy to install, these are compact devices which perform three key functions: power supply, Back Up Module and Battery Charger. The UPS range is no more than an extension of the CBI range, designed to enhance some of its particular features, such as the RS 232 connection output, dual output voltage independent.

CBI All-in-oneFor a Powerpoint presentation on the full range of CBI DC-UPS CLICK HERE and for a catalogue CLICK HERE or view below for indvidual datasheets.

CBIs integrate power supply, back-up modules and battery charging functions. These devices are based on microcontroller switch-mode technology, which optimises the times for charging and discharging accumulators without discharging the battery completely. They switch the battery onto Load without any interruptions and automatically protect output against reverse polarity, short-circuiting, overload and overcharging without a fuse. They also diagnose the internal status of the battery using the Life Test function, enable the most appropriate recharging curve to maximum efficiency of the system to be selected and guarantee batteries a long life over time, whilst enhancing their performance. With two relays output, one for Main/BackUp one for battery monitoring, they comply with the most innovative standards for battery management as well as electrical safety. DIN Rail Mountable.
