- Abstract
The pump console used at our institute is a HL20, AB, Lund, Sweden), unit with four single modular roller pumps or a combination of three roller pumps with a centrifugal pump. The unit comes with a 24-volt inbuilt battery pack in the base of the console. The batteries consist of 230-A/hour, 12-volt, gel-filled batteries. The main input voltage to the console control module is constantly monitored. Should the line voltage fall to less than 85% of the nominal voltage (220 volts), the unit automatically switches to battery This battery system will run the complete system, all pumps, supervisory modules, monitoring, and data recording in the event of power failure. The total length of battery operation time reported by the manufactures of a complete system, one arterial at per minute (LPM) (156 rpm), three ancillary pumps (50 rpm), pump display and system monitoring is approximately 1.5 hours. Battery operation time depends on the conditions of the battery and the load powered by the batteries.
