Power Requirements
The transceiver operates from an ac mains supply, or a dc input supply. When both supplies are
connected, the dc input acts as an automatic backup for the ac mains.
ac input supply The transceiver operates from a 48 to 62 Hz single-phase ac supply
and automatically adjusts to operate from any supply voltage ranging
from 110 Vac to 240 Vac ±10%. The power consumption figures are
given in Table 1.
dc input supply The transceiver operates from a dc input supply between 21.6 and
32 V (measured at the radio’s input). The supply current figures are
given in Table 1.
Dimensions and Weight
The dimensions and weight of the transceiver are:
Width 483 mm (19 inches).
Height 88.9 mm (3.5 inches). The height occupies 2U of equipment cabinet
space.
Depth 430 mm (16.9 inches) measured from front panel to rear panel.
Depth 450 mm (17.8 inches) measured from front panel to rear of fan.
Weight 13.5 kg (29.76 pounds).
Environmental
Temperature range The transceiver operates to specification across the temperature
range of -20 to +55°C.
The transceiver can be stored at temperatures ranging from
-30 to +70°C without causing any damage.
Humidity The transceiver operates to specification at a relative humidity
between 5% and 90% non-condensing.
Altitude The radios operate to specification up to 15,000 feet. Additionally the
equipment is capable of storage at altitudes up to 50,000 feet without
damage.
Shock and vibration The radios comply with shock and vibration protection MIL-STD-810E,
method 516.4, procedure VI - Bench Handling. In all cases, no fixed
parts become loose. No movable part or permanently set adjustment
shifts its setting or position.
