Description
The FXC7000 Series of standalone or rack-mounted
power systems provides true AC front-end capability to
automatic test equipment, telecom, data commun-
ications, and other distributed power designs. The FXC
systems may be paralleled up to 210 kW of output power
and are intended for chassis-mounted installations with
bolted connections. These power supplies provide
excellent protection against input voltage transients.
The FXC has its fan located at the front of the supply, and
voltage adjust, indicator lights, output bussbars, and
connectors on the rear. Airflow is from the front through
Chassis-Mountable Model
? Front panel selectable-input-range
the rear. Alarm, monitoring, and control signals are
floating from the main output and can be referenced to
the positive or negative output or sense line of the power
supply. The output is floating with respect to the chassis
and may be used as a positive or negative polarity
supply.
The FXC7000 Series meets international safety
requirements and is CE Marked to the Low Voltage
Directive. This series operates on three-phase European
voltages as well as (up to) 480VAC, delta or wye.
