2.2.3 OUTPUT POWER CONNECTION
Output power connection is made at terminals at the back of the power source.
2.2.4 CHASSIS SLIDE MOUNTS
The chassis of the AMX-Series Power Source is designed to accept slide rails. These can
be provided as a cost option. For more information, contact your local sales representative
or the Pacific Power Source Sales Office.
2.3 ENVIRONMENTAL SPECIFICATIONS
This paragraph lists the environmental requirements of the AMX-Series Power Source.
2.3.1 TEMPERATURE RANGE
The AMX-Series Power Source is rated for full operation in ambient temperatures of 0 - 55

C
and where the relative humidity is in the range of 0 - 95%, non-condensing.
2.3.2 COOLING
The AMX-Series Power Source utilizes thermally regulated forced-air cooling to maintain
proper temperatures throughout. The maximum airflow of each model is as following.
Maximum Airflow Models
100 CMF 105-AMX,108-AMX,305-AMX and 308-AMX
200 CMF 112-AMX and 312-AMX
300 CMF 125-AMX and 320-AMX
600 CMF 140-AMX,160-AMX,345-AMX and 360-AMX
1200 CMF 390-AMX and 3120-AMX
2.3.3 THERMAL PROTECTION
The input power transformer is configured with a thermocouple which senses its temperature.
The power amplifier assemblies are also configured with temperature sensors. When the
transformer or any power amplifier exceeds maximum safe operating temperature, the output
relays are opened, disconnecting the load, and the Shutdown Lamp, located on the front
panel, is lighted.
The overtemperature shutdown fault must be manually reset. The fault can only be reset
after the over-temperature condition has ceased to exist and the Output Power Switch is
placed in the "
OFF
" position. Sending an Output Off command via the remote interface
(applies to programmable systems only) also resets a shutdown fault, provided that the
condition which originally caused the shutdown has been cleared. If the Output is turned off
and the shutdown condition has not been cleared, the power source will remain in the
shutdown state until the offending condition has cleared.
