SPECIALLY DESIGNED CIRCUITS PROVIDE INVERTER PROTECTION
UNDER VOLTAGE PROTECTION:
Provides protection for the inverter so that the inverter
is automatically turned off before a malfunction due to
low voltage.
AC-DC SHORT PROTECTION
Isolated output terminals are provided to protect against
ground faults.
OVER-VOLTAGE PROTECTION:
Special circuitry is provided to automatically turn OFF the
inverter if the DC voltage exceeds maximum rated input
voltage.
CURRENT LIMIT:
Ferroresonant transformer limits the load current under
over-load conditions.
REVERSE POLARITY PROTECTION:
Special circuitry is provided in the event that the
input cables are connected in reverse polarity
