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.
High Temperature
ATTENTION
1. AVR can be mounted directly on the engine,
genset, switchgear, control panel, or any position
that will not affects operation. For dimension
reference, please see Figure 1.
2. All voltage readings are to be taken with an
average-reading voltmeter Meggers and
high-potential test equipment must not be used.
Use of such equipment could damage the AVR.
3. Secure all wiring connection. Do not install AVR at a
place with high vibrations to prevent loose
connections. For safety do not touch the heat sink
while in operation.
4. Fuse specification : 16A / 250V slow blow type.
5. Terminal："Fast-On" terminals 6.35mm (1/4 inch) &
With 4mm crimping terminal.
