Viking 242-2009-632 Two-Way Radio User Manual


 
INSTALLATION

March 1999
Part No. 001-2009-600
2.6.1 AC INPUT REQUIREMENTS
AC Input Voltage: 100-240V AC
Line Frequency: 50-60 Hz
AC In-rush: 60A maximum
Overall Efficiency: >70% at 100V AC
>80% at 240V AC
Lightning protection: 6kV for < 1ms
Power Factor: >0.97 at full load
Brown Out Voltage: 80V AC
Temperature -30°C - +60°C (full power)
Power factor correction per IEC555. The Power
supply has the following safety agency approvals
pending: UL1950, CSA22.2-950, TUV EN60950
(IEC950)
When the AC input voltage is below 90V AC, the
maximum output power is decreased to keep the input
current constant. If a battery back-up is installed, the
batteries take over when the AC input voltage falls
below 80V AC (dependent on power output).
The AC input connector is an IEC connector
equipped with a locking mechanism.
The operating temperature range is -30°C to
+60°C (-22°F to +140°F), i.e. the same as the repeater.
The fan is thermostatically controlled by the internal
temperature. When the internal heatsink temperature
reaches +45°C (113°F) the fan turns on. When the
heatsink temperature drops below +35°C (95°F) the
fan turns off. If the internal heatsink temperature
reaches +90°C (+194°F) the power supply turns off
until the heatsink temperature drops below +85°C
(+185°F). The over-temperature shutdown and restart
are automatic.
2.7 GROUNDING
CAUTION
PROPER SITE GROUNDING AND LIGHTNING
PROTECTION ARE VERY IMPORTANT TO PRE-
VENT PERMANENT DAMAGE TO THE REPEATER.
As in any fixed radio installation, measures
should be taken to reduce the possibility of lightning
damage to the Viking VX equipment. Proper ground-
ing eliminates shock hazard, protects against electro-
magnetic interference (EMI) and lightning.
