Product description


The EA16 AVR is an update of the EA15A AVR. It is similar to the original EA15A in power and voltage sensing capabilities but with new enhanced paralleling functions; the user can now select the CT inputs either 1 & 5 Amp or use new A1 & A2 analogue signal inputs terminals for use with PLC paralleling controls. It has new over-voltage excitation safety circuits to prevent damage caused by the accidental detachment of the sensing wires or irregularities on the generator’s excitation circuits.
