AMX Series – Programmable AC Power Source

Take control of your AC power.

The AMX Series is a family of High Performance 1 phase and 3 phase Linear AC Power Sources. All standard models operate from 20 to 5,000 Hz, range in power from 500VA to 90kVA, and provide nominal output voltage ranges up to 600Vrms L-N.

For questions regarding the AMX Series and or custom solutions, please contact us directly or try our live chat.

Overview

When power quality matters, the AMX Series family of High Performance Linear AC Power Sources is the answer.  The linear amplifiers within the AMX Series power sources are unmatched in their ability to produce the high crest factor, low-distortion, high fidelity output waveforms required by the most demanding AC Test Power applications.  Stand-alone models range from 500 VA to 6 kVA.  Larger chassis may be paralleled to create systems that range from 9 to 90 kVA.  Offering both single and three phase models, units are conservatively designed with output power ratings are based on the most severe combination of input line, output voltage, power factor, and temperature.

Great emphasis has been placed on low acoustic noise, ease of installation, and safety. Control and operating features provide a high degree of application versatility and ease of use for the test engineer. Applications range from simple, manually controlled frequency conversion to power-line susceptibility testing and sophisticated bus programmable transient simulation.

The exceptionally broad bandwidth (50 kHz small signal), combined with low output impedance and high crest factor ratings give the AMX Series the ability to produce high quality, low distortion output power into the most dynamic loads.

Special AMX Series Operating Features

Continuous Self Calibration

Provides for exceptional accuracy of the AC output Voltage. When enabled, accuracy improves to ±0.03% referenced to the power source internal voltmeter.

Programmable Dynamic Output Impedance (optional on UPC12/32)

Programmable Output Impedance provides the operator with dynamic control over the output impedance of the AC Power Source. Using the output current term as conditioned feedback signal to the output voltage circuits, positive or negative impedance may be programmed. The purpose of this control is to simulate the effects of or compensate for high peak current, distribution, or transformer losses of up to ±10% of the output voltage.

This feature creates positive, negative, or zero output impedance (Zo).

  • Compensates for line distribution or transformer losses.
  • Simulates a soft power line for product testing. Compensation range is ±10% of the output voltage.
Waveform Library

Up to 16 different waveforms can be stored in the waveform library for execution as part of a steady state program or for substitution in any output phase as part of a transient test program. Memory location #1 is a non-editable high resolution sine wave. Locations 2-16 are editable and can be substituted in any output phase. An unlimited number of waveforms may be stored on the computer for those using a programmable UPC.

Waveform Edit

Provides the ability to modify a stored waveform by specifying the waveform amplitude desired at each specific phase angle.

Waveform Analysis (optional on UPC12/32)

Provides both a graphic and numeric display of the harmonic structure of a voltage or current waveform. Data presented includes the magnitude of each harmonic in %, the total harmonic distortion, and the odd and even harmonic distortion in %.

Waveform Synthesis (optional on UPC12/32)

Provides the ability to quickly create virtually any AC Test Waveform that may be required by building it out of harmonics. The process is as simple as keying in the harmonic multiple, the amplitude, and the phase angle for each desired harmonic up through the 51st.

Time Based Transients

Provide the ability to create and execute on command, transients that occur linearly over a specified time segment to modify output voltage or frequency.

Cycle Based Transients

Provide the ability to create and execute, on command, transients that substitute a selected waveform in the output for 1 to 100 cycles.

Applications

AC Test Power

The AMX Series Power Source is equipped with a powerful microcontroller 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 AMX Series is an excellent source of stable AC voltage over the frequency range of 20 to 5,000 Hz. The output frequency is quartz-crystal stabilized. Output voltages up to 600 VAC are provided.

 Phase Conversion

With the ability to provide single and three-phase outputs, the AMX Series is the perfect choice to provide 1 Phase to 3 Phase or 3 Phase to 1 Phase conversion.

Controller Selection Guide

Four controller models are available with the AMX-Series. They include 1 Phase and 3 Phase models for both manual and programmable control.

  • UPC-12, 1 Phase Programmable Control, 20 Hz to 5,000 Hz.
  • UPC-32, 3 Phase Programmable Control, 20 Hz to 5,000 Hz.
  • UPC-32E, Export version, 3 Phase Programmable Control, 20 Hz to 5,000 Hz, reduced resolution.

All controllers provide manual operation from the front panel. Programmable Controllers may be programmed from the front panel or from a remote interface. IEEE 488 interface is standard. RS232 interface is optional.

Dual Range Output Magnetics Options

AMX Series Power Sources can be equipped with output transformers to provide an alternate output voltage range. Selection of direct or transformer coupled range is performed by the controller via front panel or bus command. The standard frequency range for transformer coupled outputs is 45 to 5,000 Hz. Standard output ratios are 1.5:1, 2.0:1, and 2.5:1. Transformer outputs are supplied internally or externally via a Magnetics Module as listed in the above table.
