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

Take Control of Your AC Power.

The AMX Series is a family of High Performance Linear AC power sources covering the power range from 500 VA to 12 kVA with standard models and up to 30 kVA with optional M5283 option.

UPC Controller Specifications

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.
