Operating voltage
GLT80TDC 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
• Standard (Default):
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
• Special (programming option):
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
Serial Port Interface, using the FxC programming
package provided by the manufacturer upon
request.
