Product description

 This EA16 is for 400 Hz system.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.

Main features:

1、KUTAI EA16 Can Used In Parallel Operation.

2、Soft Start Voltage Ramping  

3、Load CT Current Compensation, Analogue Voltage Input 

4、Suitable for brushless style generator sensing Input 170~510VAC
