    Three Phase AC Voltage Controller

    Nvis 7044

    Product Description

    Nvis 7044 Single and Three Phase AC Voltage Controller is a useful Training System for Power Electronics Lab to demonstrate the operational working of Single and Three Phase AC Voltage Controller. It includes the experiment such as speed control of Three Phase AC Motor through anti- parallel SCR configurations with fine control response, speed control of single phase universal motor through TRIAC and anti parallel SCR configuration. It helps students to know how to generate firing pulses for three phase controller using ramp comparator scheme.

    Nvis 7044 is equipped with SCR firing control circuit that deals with triggering, modulation and instrumentation deriving the operating characteristics and capabilities of Controllers. It incorporates all the necessary test points in order to explain the gate circuit by analyzing gate waveforms through inbuilt Power Scope.
