Dimensions 156mm L * 106mm W * 41mm H Weight 450g ± 2% 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.
