SECTION 1 GENERAL
1.3 GENERAL PRODUCT DESCRIPTION
The ACX Power Source is a high-performance AC power conversion instrument. It is intended
for indoor use and the chassis is designed to fit into a standard 19 inch instrument rack or to be
used on any test bench surface. The power source is suitable for use as a frequency converter
as well as for sophisticated AC test power generation.
These power sources are configured with a digital controller. Controller type is:
UPC1 for sophisticated programmable control - provides all of the manual control
capability, plus a wide variety of additional features including program storage, waveform
editing, and remote interface (Serial standard or GPIB optional).
Model ACX has dual-range output voltage capability, able to operate at either 0-150 volts or
0-300 volts. When operated in the high voltage range, the output may be used as either a
single-ended or split-phase configuration. The phase separation of L1 and L2 is fixed at 180
degrees in that case. Optional output transformers can be provided for higher or lower voltage
range.
Output power is up to 1.8kVA at any nominal input voltage from 115 to 240 Vac.
External Voltage Sense capability is provided and will display the actual voltage at the remote
sense location. The CSC (Continuous Self Calibration) feature will allow the controller to
regulate the voltage at the sense location.(CSC)
Output voltage and current metering is provided on the system display. Specifications of the
metering functions are described in the UPC Series Operation Manual.

SPECIFICATIONS
2 SPECIFICATIONS
This section states the electrical and mechanical specifications of the ACX Power Source.
Some specifications are controller dependent and are noted as such.
2.1 ELECTRICAL SPECIFICATIONS
2.1.1 INPUT POWER REQUIREMENTS
The following input power forms are accepted by the ACX
INPUT VOLTAGE
The Model ACX accepts any single phase input voltage of 115-240 Vac, 50Hz or 60 Hz Nominal
and is tolerant of transient overvoltages typically present on the AC MAINS power distribution
lines.
INPUT CURRENT
The input current required by the ACX varies by model based on their maximum full rated load.
AC input currents shown below apply to model 118ACX for most common nominal line voltages.
Recommended input service is also stated. Lower power ACX models have proportionally lower
AC input currents. Overload conditions will result in higher input currents that still fall within the
recommended input service. However, at low AC line voltages, the AC input current is
electronically limited at 25Arms. This allows full rated power down to 115V -10% or 103VAC L-N
(Low Line Voltage).
NOTE: In low voltage operations the max input current is electronically limited to
25A
Vin INPUT CURRENT SERVICE RECOMMENDED
maximum. At least 12AWG input cable wire is recommended.
