The Unipower HPL530 is equipped with a specially developed power supply for use from 100V - 575V - both single phased and three phased. Mains voltages in the whole world is hereby covered with one unit. HPL530 also measures currents up to 40A without the use of an external current converter. As all Unipower HPL-modules the HPL530 naturally integrates the functions necessary to establish an efficient and compact supervision or control; Start timer, reaction timer, setpoints etc. The HPL530 features a special shock load supervision algorithm in addition to a standard Max/min limit. For setup simplicity the unit includes peak detectors on the power measurement. The measurement is based on a fast four quadrant multiplication of current and voltage making the HPL530 capable of measuring the exact power consumption also on frequency inverters. Measurement: P = 1.732 x V x I x Cos Phi.
