Phoenix Contact has introduced a new UPS solution for high system availability and reliability when the line supply fails. With previous UPS solutions, the buffer time was manually set without the actual battery capacity being known. However, since battery performance decreases with age or at high ambient temperatures, the battery cannot always supply energy for the buffer time that was set and power supply failures result.
The new intelligent Quint UPS-IQ uninterruptible power supply determines all of the relevant battery states – such as a voltage or temperature – to ensure the necessary reliability of the UPS at any time taking into account battery utilisation. Battery management determines the charge state of the battery and then calculates the buffer time that is available, this avoids supply interruptions and premature shut-down of industrial PCs. It also allows service to be planned and ensures energy storage devices are not replaced prematurely.
To calculate the charging current, the UPS communicates with the battery and with the power supply. As a consequence, the battery is charged faster than it would be with conventional UPS systems and the power supply output is controlled. Power supplies with output currents of 5, 10, 20, and 40 A are available for 24 V applications. All modules can be optionally combined with energy storage devices utilising VRLA technology with 1,3 to 38 A.h – or for high ambient temperatures with especially powerful Li Ion batteries. Buffer times of 8 hours with a 5 A load current or 30 minutes with a 40 A load current are achievable.
