terminal in it.
GD30FDC is designed to operate in a wide range of DC voltages, supplied either by a battery or by
any other kind of filtered DC power supply.
DC VOLTAGE SUPPLY ALLOWED: 10V to 42.4V

OPERATING VOLTAGE
Functional modes
From the value of the applied voltage, the electronic driver automatically decides the rated
voltage range of the supply. Three possible ranges are considered:
12 to 14V: actual voltage is below 17V
24 to 28V: actual voltage is within 17 and 33V
36 to 42V: actual voltage is within 33 and 42.4V
The compressor can be powered by a variable DC source as, for instance, a photovoltaic panel, in
which the output voltage strongly depends on the intensity of sunlight radiation. In these special
cases the driver should be programmed with rated, minimum and maximum voltages. These
values should be within the allowable DC voltage power supply (10 V to 42.4V).
Rated voltage and voltage limits are programmed by the appliance manufacturer by means of
a PC connected through the serial port to the driver’s Serial Port Interface, using the FDC
programming package provided by ACC under request.
