Model 3120-ASX

12kVA – High Performance AC Power Source

Single, Split, or Three Phase Frequency Converter

The Model 3120-ASX is Pacic’s latest addition to its line of Manual and Programmable AC Power Sources. Power Conversion within the ASX Series is achieved by high frequency pulse width modulation, resulting in cool, quiet and efcient operation.

The 3120-ASX is ideal for AC test, frequency conversion, laboratory and bench-power applications.

AC TEST POWER

The 3120ASX is equipped with the UPC Programmable Controller, a powerful micro-controller used to create a fully integrated test system. It supplies a variety of power conditions to the device under test and meters/analyzes all output performance parameters.

FREQUENCY/VOLTAGE CONVERSION

The 3120-ASX is an excellent source of stable AC Voltage over the frequency range of 15 to 1,200Hz. The output frequency is quartz-crystal stabilized. Output voltages up to 600V are available.

UPC SERIES CONTROLLER

The latest additions to Pacic’s family of UPC Controllers are the UPC-3M and UPC-3. The UPC Controller is a modular component of the ASX Series and is available in either Manual or Programmable Congurations.

All UPC Controllers include precise metering functions with data displayed via a 160-character LCD display. This, along with the 30-key front panel, provides the industry’s most powerful and user-friendly controller.

The UPC-3 is available with either RS-232 or GPIB remote interface. Commands are structured in accordance with SCPI (Standard Commands for Programmable Instruments). The RS-232 serial port operates up to 38.4kBps. The GPIB interface is compatible with the IEEE-488.2.

NOTES:

1. Rated output power is based on a combination of output voltage, current and load power factor. Values stated represent the maximum capabilities of a given model. Consult factory for assistance in determining speciﬁc unit capabilities as they might apply to your application.

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

3. Output voltage range is for standard unit. Vmax is output voltage with nominal input and full rated load applied. Other voltage ranges are available with the output magnetics option.

4. Peak repetitive pulse current for non-linear loads. Consult factory for overload ratings.

5. Three phase input with in-rush limiting: 208, 220, 230, 240, 380, 400, 416, and 480 VAC ± 10%.

6. Available current will vary with output voltage and power factor.

KEY FEATURES UPC SERIES CONTROLLER

PROGRAMMABLE Dynamic output impedance (ZO) is programmable OUTPUT Range varies with model, but usually results in a IMPEDANCE: ±10% change in output voltage at maximum-rated load current. (UPC-3 Option).

PROGRAMMABLE Programmable Current limit is provided on the CURRENT LIMIT: UPC-3 controllers. Programmable range is from 0 to I

WAVEFORM The UPC-3 controller contains a waveform library LIBRARY: that stores 22 executable waveforms in Non-volatile RAM. Waveforms 2-16 are editable via the front panel or bus command.

WAVEFORM Provides waveform creation by entering the SYNTHESIS: magnitude (% fund.) and phase angle for the 2nd through 51st harmonic (UPC-3 option).
