ENVIRONMENTAL SPECIFICATIONS

The environmental requirements of the ASX-Series Power Sources are:

2.3.1 TEMPERATURE RANGE

The ASX-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 ASX-Series Power Source utilizes thermally regulated forced-air cooling to maintain proper
temperatures throughout. The maximum airflow of the 140/160/345/360-ASX Magnetics Module
is 100 CFM. The maximum airflow of the Models 115-ASX, 120-ASX, 315-ASX, 320-ASX, and
the 3120-ASX Magnetics Module is 200 CFM. The maximum airflow of the Models 140-ASX,
160-ASX, 345-ASX, and 360-ASX is 300 CFM. The maximum airflow of the Model 3120-ASX is
600 CFM.

2.3.3 THERMAL PROTECTION

The input power transformer is configured with a thermocouple which senses its temperature.
Additionally, 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 and the Shutdown LED, 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.
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.
Sending an Output Off command via the remote interface (applies to
