NOTE: When the utility input is abnormal, this dry contact can control the oil engine
switch to charge the battery.
1） Remote interface
2） Remote interface input voltage( 3.3~ 12V )
(1)The input voltage Vi is within 2.5~ 10s, the AC output state is reversed (when the AC is
formerly in output state, now it is in no-output state ; when the AC is formerly in no-output state,
now it is in output state;)
(2) The input voltage Vi is greater than 10s, the AC is in output state all the time till the input
voltage Vi disappears.
NOTE: If it is to change the range of input voltage, it can be realized by changing the
resistance value of R.
