Machine Protection, 3x415Vac, 1 X SPCO 1 X SPNO
The Unipower HPL540 is equipped with a specially developed and patented power supply for use from 100V – 575V – both single phased and three phased (Patent no. PR177225). Mains voltages in the whole world is hereby covered with one unit. HPL540 also measures currents up to 40A without the use of an external current converter. The Unipower HPL540 is specifically developed for load protection of conveyance machinery; when a conveyor transport is blocked the HPL540 reverses the transport direction in order to automatically recover the fault. The number of reversals as well as the reverse time are programmable. For setup simplicity the HPL540 includes peak detectors on the power measurement.
The measurement is based on a fast four quadrant multiplication of current and voltage making the HPL540 capable of measuring the exact power consumption also on frequency inverters. Measurement: P = 1.732 x U x I x Cos Phi.
