AMX Series

 

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 30 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.

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.

The UPC controller is essentially a single or three phase AC arbitrary waveform generator and Precision AC metering system. The waveform for each phase may be independently selected and may be independently varied in amplitude and phase angle with respect to phase A (3 phase systems).

The UPC output metering samples the output volts and amps at 512 samples per measurement using a 12 bit A/D converter. This technique provides exceptional metering accuracy and resolution (20 bits), and delivers a high-fidelity waveform back to a host computer for analysis.

The UPC includes a remote GPIB interface compatible with IEEE 488.2 and SCPI. An available option is an RS-232 serial port that operates up to 38.4 kBaud.
