2.2.2 INPUT POWER CONNECTION

Input power is brought into the ACX at the Input Power terminal block on the rear panel.

2.2.3 OUTPUT POWER CONNECTION

Output power is taken from the ACX Power Source via rear panel mounted terminal blocks.
Remote Sense terminals are also provided at this terminal block.
Terminal block TB5 on the rear of the ACX may be used to remotely enable/disable the output of
the power source. An electrical connection between terminals TB5-1 and TB5-3 enables the
output of the ACX allowing normal operation from the front panel or remote interface. An open
connection between TB5-1 and TB5-3, disables the output of the ACX. The ACX is supplied
with a jumper installed in TB5 such that the output is enabled. That jumper may be replaced by
a switch or relay which can operate as a safety interlock or remote disconnect.

2.2.4 CHASSIS SLIDE MOUNTS

The ACX Power Source is designed to accept slide rails for mounting in a 19" Instrument
Cabinet. These rack slides can be provided as a cost option. Contact your local sales
representative or the Pacific Power Source Sales Office.

ENVIRONMENTAL SPECIFICATIONS

2.3.1 TEMPERATURE RANGE

The ACX Power Source is rated for full operation in ambient temperatures of:
0 - 40°C, relative humidity in the range of 0 - 95%, non-condensing.
Operation from 40°C to 55°C is permitted with output power decreasing linearly with increasing
ambient temperature. Available power at 55°C is 600W.

2.3.2 COOLING

The ACX Power Source utilizes thermally regulated forced-air cooling to maintain proper
temperatures throughout. The maximum airflow is 240 CFM.

2.3.3 ALTITUDE

The ACX Power Source is rated for full operation at altitudes of:
0 – 10,000 feet/3,000m.

2.3.4 POLLUTION DEGREE

The ACX Power Source is rated for full operation in environments of mild pollution severity and
humidity referred to as Pollution Degree 2. These conditions are typically present in office,
laboratory and ATE environments. Normally only nonconductive pollution occurs. Temporary
conductivity caused by condensation is to be expected.

2.3.5 THERMAL PROTECTION

Temperature sensors are installed in the power assemblies. If safe operating temperature is
exceeded, the output is opened and the Shutdown LED on the front panel, is lighted. A
shutdown fault must be reset to restore normal operation. See paragraph 4.5 for details.
