AMX Series

112AMX

Power: 1200VA

Voltage range: 0-150/300V (Dual Range)

Current range: 0-10/5Arms, 40/20Apk

Single phase

The AMX Series is a family of High Performance Linear AC power sources covering the power range from 500VA to 12kVA with, single chassis models, and up to 30kVA with multi chassis systems. The product line offers both single and three phase models. Units are conservatively designed and output power ratings are based on the most severe combination of input line, output voltage, power factor, and temperature. This approach to product design allows the AMX Series to excel when delivering the high peak load currents demanded in the AC test environment.

Great emphasis has been placed on low acoustic noise, ease of installation, and maximum power per cubic inch of rack space. 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 harmonic testing and sophisticated bus programmable transient simulation.

An exceptionally broad bandwidth (50kHz small signal) combined with peak/RMS current of 4-6:1 give the AMX Series the ability to produce high quality, low distortion output power into the most dynamic loads.

All AMX Series power source models may be equipped with either a digitally programmable Oscillator/Controller or a manually controlled Oscillator.

Single phase power source models may be controlled to operate on either a 0-135VAC range or a 0-270VAC range. Three phase models are additionally switchable to 3ø/1ø output power form.

Total control of the output power form and the selection of either the direct output or the optional transformer output is available from the front panel or the bus.

All operating functions may be controlled from either the front panel or from a remote RS-232 or IEEE 488.2/ SCPI BUS. LabVIEW for Windows® and LabWindows® Instrument Drivers are available.

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)

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)

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)

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.
