Automatic power factor regulator EPF series

Automatic power factor regulator with microprocessor management for 6 and 12 steps activation, with THD I% control regulator, RS485 serial connector available on the base of the model. This device has been designed with a technology to elaborate also very distorted signal able to assure an accurate control of plant electrical values like voltage, current, power factor, internal temperature of the equipment, voltage harmonic distortion. All electrical measurements are made by a complete analysis through FFT (Fast Fourier Transformer) of the wave shape with floating-point Using a reliable calculation algorithm, the regulator is able to operate the capacitor steps, switching-in/ switching-off the reactive power needed at the fixed aim, reducing drastically the number of switchings and using in an homogenous way the various steps. Four keys allows access to parameterizations and to the dedicated measures. The measures are made in real effective value (True RMS) calculating the power factor directly between voltage and current. The setting up of each battery is made simply switching-in independently its rated value, for each step that must be set, allowing an easy comprehension and reading of the set parameters.
