2.2.3 OUTPUT POWER CONNECTION

Output power is taken from the AMX-Series Power Source via rear panel mounted terminal blocks.

2.2.4 CHASSIS SLIDE MOUNTS

The chassis of the AMX-Series Power Source is designed to accept slide rails. These are provided as a cost
option. For more information, contact your local sales representative or the Pacific Power Source Sales Office.

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 the Models 105-AMX, 108-AMX, 305-AMX, and 308-AMX is 100
CFM. The maximum airflow of the Models 112-AMX and 312-AMX is 200 CFM. The maximum airflow of
the Models 125-AMX and 320-AMX is 300 CFM. The maximum airflow of the Models 140-AMX, 160-AMX,
345-AMX, and 360-AMX is 600 CFM. The maximum airflow of the Models 390-AMX and 3120-AMX is
1200 CFM.

2.3.3 THERMAL PROTECTION

The input power transformer is configured with a thermocouple which senses its temperature. Additionally, the
power amplifier PCB assemblies are also configured with temperature sensors. When the transformer or any
power amplifier PCB exceeds maximum safe operating temperature, the output relays are opened and the
Shutdown Lamp, located on the front panel, is lighted.
The shutdown fault is implemented such that it must be manually reset. The fault can 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
the shutdown fault, provided that the condition which originally caused the shutdown has been cleared. If the
Output On/Off command is sent via the remote interface and the shutdown condition has not been cleared, the
power source will remain in the shutdown state until the offending condition has cleared.
