1.0 GENERAL
This manual is written to provide the information required to use the AMX-Series AC Power Source. Operation
of the Models 105-AMX, 108-AMX, 112-AMX, 125-AMX, 140-AMX, 160-AMX, 305-AMX, 308-AMX, 312-
AMX, 320-AMX, 345-AMX, 360-AMX, 390-AMX, and 3120-AMX is described in this document.
This manual is an Operations Manual. Installation, operation, and calibration are the subjects covered by this
manual.
1.1 USING THIS MANUAL
This manual provides instructions for installation and use of the AMX-Series Power Source equipment. For this
reason, it is very important that the user reads sections 1, 3, and 4 prior to using this equipment. A thorough
understanding of these sections is required to properly operate this equipment.
Section 2 states the specifications of the equipment. Knowledge of this information is required to gain
maximum use of this equipment for a given application. The user is encouraged to read this section in order to
gain a deeper understanding of the capabilities of the AMX-Series Power Source.
Sections 5 and 6 list maintenance and calibration requirements of this equipment. Refer to these sections when
either maintenance or calibration is required.
Section 7 describes service methodology and provides system, sub-assembly, and component part numbers to
aid the user in making factory authorized field repairs.
This equipment is configured with a modular controller. This allows for the creation of systems with various
control characteristics and specifications. This manual describes the operation of the basic power source.
Detailed information relative to the UMC-31 Controller is also included is described in Section 8 of this
manual. The UPC controllers are described in a separate manual. Refer to the UPC-Series Operation Manual
for such information.
Section 9 contains product change notices, errata and data relative to customer specified modifications.
Always read this section before operating the equipment. This is especially true when modifications have been
installed, since these can change system operation.
If questions arise while reading this manual, the user is encouraged to call the Pacific Power Source. Pacific
maintains a toll-free number which is 1-800-854-2433.

1.3 GENERAL PRODUCT DESCRIPTION
The AMX-Series Power Source is high-performance AC power conversion equipment. This series of
equipment features models with power ratings from 500 VA to 12 kVA. All systems are designed to fit into the
standard 19 inch rack. These systems are suitable for use as frequency changers as well as sophisticated test
power generators.
All systems are configured with an interchangeable controller. Controller options range from the basic manual
type (UMC-Series) to the sophisticated programmable controller (UPC-Series). The manual controller allows
the user to adjust voltage and frequency. The programmable controller, on the other hand, not only allows
control of voltage and frequency, but also allows the user to simulate virtually any transient (including sub-
cycle waveform disturbance) required for testing today's modern electronic equipment.
The standard output voltage range of the AMX-Series is 0-135 VACl-n (0-150 VACl-n for the Model 125-AMX).
Additionally, the Models 112-AMX and 312-AMX can be configured for several output voltage ranges
between and including 0-110 VACl-n and 0-150 VACl-n. Optional output transformers are available to provide
higher voltages. Voltage ratios up to 2.5:1 are available.
The AMX-Series consists of the basic models listed below:
1. Model 105-AMX - 500 VA Chassis capable of 1 or 2 Phase operation. Standard
Output voltage range is 0-135 VACl-n, 1φor 0-270 VAC, 2 Phase. Phase separation fixed at 180°
when operating in 2 Phase Mode.
2. Model 108-AMX - Same as 105-AMX, but rated for 750 VA output power.
3. Model 112-AMX - Same as 105-AMX, but rated for 1.2 kVA output power. Standard
Output voltage ranges are 0-110 VACl-n through 0-150 VACl-n, 1φor 0-220 VAC through 0-300 VAC,
2 Phase.
4. Model 125-AMX - Same as 105-AMX, but rated for 2.5 kVA output power. Standard
Output voltage range is 0-150 VACl-n, 1φor 0-300 VAC, 2 Phase.
5. Model 140-AMX - Same as 105-AMX, but rated for 4.0 kVA output power.
6. Model 160-AMX - Same as 105-AMX, but rated for 6.0 kVA output power.
7. Model 305-AMX - 500 VA Chassis capable of 1, 2, or 3 Phase operation. Standard
Output voltage range is 0-135 VACl-n. Phase separation fixed at 180°when operating in 2 Phase
Mode. In 3 Phase Mode, phase separation is fixed at 120°or programmable.
8. Model 308-AMX - Same as 305-AMX, but rated for 750 VA output power.
9. Model 312-AMX - Same as 305-AMX, but rated for 1.2 kVA output power. Standard
Output voltage ranges are 0-110 VACl-n through 0-150 VACl-n, 1φor 0-220 VAC through 0-300 VAC,
2 Phase.
10. Model 320-AMX - Same as 305-AMX, but rated for 2.25 kVA output power.
