The Unipower HPL110A is a low cost member of a family of Intelligent Power-Control Units. The unit measures true power consumption and shows the consumption as a percentage of the selected power range. The power-consumption (kW) is calculated from the following formula: P = 1.732 x V x I x PF The primary function of the HPL110A lies in the supervision and control of machinery driven by 3-phased AC-motors. The HPL110A integrates a Max. and/or a Min. kW limit detector plus the support functions, including a peak detector, which are necessary to establish the efficient and compact supervision or regulation of various types of machinery such as pumps, fans and conveyer belts. The HPL110A has a built in current converter that works up to 8 Amps.
