Model 320AMX

As a member of Pacic Power’s AMX-Series popular family of high performance Linear AC Power Sources, the 320AMX oers the same low output voltage noise and distortion, ease of installation, and high AC waveform delity as found in all of Pacic Power’s Linear AC Power Sources. Control and operational features provide a high degree of versatility and ease of use for applications ranging from simple, manually controlled frequency conversion to harmonic testing and sophisticated programmable transient simulation.

AC TEST POWER

All 320AMX and 320AMXT models are equipped with a powerful micro-controller with the ability to operate as a fully integrated test system. This enables a variety of power conditions and transients to be applied to the device under test while metering and analyzing all output performance parameters. For higher power requirements, refer to the AMX & ASX series catalog.

FREQUENCY/ VOLTAGE CONVERSION

The 320AMX is an excellent source of stable AC Voltage over the frequency range of 20 to 5,000 Hz (Direct Coupled Range) or 45 to 5,000 Hz (Transformer Coupled AMXT models) when using the high-end UPC-32 controller. Also available in 1,200 Hz maximum output frequency when using UPC3 or Manual controller. The output frequency is quartz-crystal stabilized. Output voltages up to 270V mode are available on the 320AMX model and up to 600V 320AMXT model.

PHASE CONVERSION

With the ability to provide either single or two phase output, the 320AMX is a good choice to convert three-phase line voltage into precisely controlled split (two-phase) or singlephase output power.

NOTES:

1. Rated output power is based on a combination of nominal output voltage, rated current and load power factor. Values stated represent the maximum capabilities of a given model (maximum power in split phase (Form2) direct coupled mode is 1.3 kVA). Consult factory for assistance in determining specic unit capabilities as they might apply to your application.

2. Unit is operable as single phase with dual range capability or 3 phase. Output voltage range and 1/2/3 conversions are selected by front panel or bus commands.

3. Vmax is output voltage with nominal input and full rated load applied.

4. Available current will vary with output voltage and power factor. Current shown is per phase.
