Three phase microprocessor phasе regulator LFR31

Code: LFR31
Description

LFR31-16 is a three-phase microprocessor phase regulator, which is used for gradual regulation of the power in three-phase active-inductive loads, such as asynchronous engines or heaters. It’s possible to set upper and lower limit of the power and the revolutions. There are three modes of control: manual by the regulator itself, manual by external potentiometer and automatic by analog signal 0-10 V. There is possibility for remote control turning-on and switching–off as it provides gradual start and avoids starting current. Thermal protection input with indication. Protection against incorrect order of the phases and protection against dropping out of some phases.
