EPF
• 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.
• Further to the normal functions the EPF12T PF regulator shows the network and in case of a signal highly EPF 12T440 distorted it protects the capacitor batteries disconnecting them from the network; it controls also the internal temperature of the equipment and in case of too elevated internal temperature, it sequently disconnects the switched-in batteries. It records alarm situations and the number of switchings made by each battery, to be able to verify their wear.
• All the batteries can be set in “FIX” mode, that is to say not operated by the device in an automatic mode, but fixed in the line and always protected in case of critical situations.
• In the full respect of current standards it also checks eventual micro-interruptions and/or voltage “holes” protecting capacitors, re-energizing them only after discharge transients.
• All the parameterizations and information, are available on the RS 485 serial connectors.
