5. Other functions
5.1 Dry contact
Working principle: This dry contact can start and stop the generator to
charge the battery. ① Normally, the terminals are that the NC-N point is closed and
the NO-N point is open; ② When the battery voltage reaches the low voltage
disconnection point, the relay coil is energized, and the terminals turn to that the
NO-N point is closed while NC-N point is open. At this point, NO-N point can drive
resistive loads: 125VAC/1A, 230VAC/1A, 30VDC/1A.
