Mono-phase microprocessor phase regulator LFR11

Code: LFR11

LFR11 is a mono-phase microprocessor phase regulator, which is used for gradual regulation of the power in mono-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.
