Controller Capabilities
The MX Series uses a sophisticated digital signal processor based arbitrary waveform generator and power analyzer. This integrated, multi instrument approach, effectively eliminates the need for additional equipment to create an complete AC and DC power test system. Using a large graphical LCD display, the advanced measurement and analysis capabilities can be accessed directly from the front panel without the need for remote control. For ATE applications, both IEEE-488 and RS232C interfaces are included and Windows™ Graphical User Interface application software comes with each MX unit.

Flexible Configurations
Configuration options include both single and multiple unit systems for a wide range of power levels. The MX45-3Pi offers both single and three phase output capability at a power level of 45 kVA. Multiple MX45 chassis can be combined to provide higher power levels for three phase applications.

Applications
The extended output frequency range of 16 Hz to 819 Hz makes the MX Series suitable for both commercial and avionics applications. Dual voltage ranges (3Pi models or -R option) provide maximum output current at 80 % of voltage range and constant power from 80 to 100 % of V range. The built in measurement and analysis functions eliminate the need for additional test equipment.

Instrument Control Software

All MX Series AC/DC power systems include a Windows™ Graphical User Interface (GUI) program. The GUI supports all functions and capabilities of the MX Series. The following tasks can easily be performed through this graphical user interface using either the IEEE-488 or RS232C interface:

• Define custom waveforms by specifying their harmonic content
• Define custom waveforms by free-hand drawing with the mouse
• Capture output voltage and current waveforms

Introduction

The MX Series consists of multiple high power AC and DC power systems that provide controlled AC and DC output for ATE and product test applications. This high power AC and DC test system covers a wide spectrum of AC and DC power applications at an affordable cost. Using state-of-the-art PWM switching techniques, the MX series combines compactness, robustness and functionality in a compact floor-standing chassis, no larger than a typical office copying machine. This higher power density has been accomplished without the need to resort to elaborate cooling schemes or additional installation wiring. Simply roll the MX15, MX30, or MX45 unit to its designated location (using included casters), plug it in, and the MX series is ready to work for you.

Simple Operation

The MX Series can be operated completely from its menu driven front panel controller.

A backlit LCD display shows menus, setup data, and read-back measurements.

IEEE-488 and RS232C remote control interfaces and instrument drivers for popular ATE programming environments are available. This allows the MX Series to be easily integrated into an automated test system.

For advanced test applications, the programmable controller version offers full arbitrary waveform generation, time and frequency domain measurements, and voltage and current waveform capture.

Configurations

The MX15 delivers up to 15 kVA of single phase output. The MX30 delivers up to 30 kVA, and the MX45 up to 45 kVA. Both operate using single or three phase output in AC mode. In DC mode, 65 % of the AC power level is available. On MX models with the programmable controller, an AC+DC mode is also supported.

Increasingly, manufacturers of high power equipment and appliances are required to fully evaluate and test their products over a wide range of input line conditions. The built-in output transient generation and read-back measurement capability of the MX Series offers the convenience of a powerful, and easy to use, integrated test system.

With an output frequency range to 819 Hz (or 1000 Hz with -HF option), the MX Series is well suited for aerospace applications.

Precise frequency control and accurate load regulation are key requirements in these applications. The available IEEE-488 control interface and SCPI command language provide for easy integration into existing ATE systems. The MX Series eliminates the need for several additional pieces of test equipment, saving cost and space. Instrument drivers for popular programming environments such as National Instruments LabView™ are available to speed up system integration.

As governments are moving to enforce product quality standards, regulatory compliance testing is becoming a requirement for a growing number of manufacturers. The MX Series is designed to meet AC source requirements for use in compliance testing (see the MX-CTS Datasheet for more info).

The MX30 and MX45 can be ordered with either a 150 V RMS Line to Neutral output voltage range or a 300 V RMS Line to Neutral range. This provides 3 phase output capability of 260 Vac or 520 Vac line to line respectively. If dual output ranges are required, the programmable range change option (-R) provides the ability to switch between both output ranges. Pi version models offer standard dual voltage ranges.

The DC output mode changes the 150 V AC range to a 200 V DC output range; the 300 V AC range becomes 400 V DC.

For applications requiring more than 300 V L-N (or 520 V L-L), the optional -HV1 output transformer provides an additional 400 V L-N and 693 V L-L output range for use in AC mode only.

For high power applications, two or three MX45 chassis can be combined to provide 90 to 270 kVA of three phase power.

MX90 and MX135 systems are always configured for three phase operation. Contact sales for custom configurations.

With a crest factor of up to 3:6, the MX Series AC source can drive difficult nonlinear loads with ease. Since many modern products use switching power supplies, they have a tendency to pull high repetitive peak currents. The MX30-3Pi can deliver up to 200 Amps of repetitive peak current (150 V AC range) per phase to handle three phase loads. The MX45-3Pi can deliver up to 300 Amps. 600 Amps (MX30), and 900 Amps (MX45).

MX Series - Waveform Generation [Pi controller]

Using the latest DSP technology, the MX Series programmable controller is capable of generating harmonic waveforms to test for harmonics susceptibility.

The Windows Graphical User Interface program can be used to define harmonic waveforms by specifying amplitude and phase for up to 50 harmonics. The waveform data points are generated and downloaded by the GUI to the AC source through the IEEE-488 or RS232C bus. Up to 200 waveforms can be stored in nonvolatile memory and given a user defined name for easy recall.

All MX-Pi Series configurations offer three phase waveform generation, allowing independent phase anomalies to be programmed. It also allows simulation of unbalanced harmonic line conditions.

MX Series - AC and DC Transient Generation

The MX Series controller has a powerful AC and DC transient generation system that allows complex sequences of voltage, frequency and waveshapes to be generated. This further enhances the MX’s capability to simulate AC line conditions or DC disturbances. When combined with the multiphase arbitrary waveform capabilities, the AC and DC output possibilities are truly exceptional. Transient generation is controlled independently yet time synchronized on all three phases. Accurate phase angle control and synchronized transient list execution provide unparalleled accuracy in positioning AC output events.

Transient programming is easily accomplished from the front panel where clearly laid out menu’s guide the user through the transient definition process.

The MX Series is much more than a programmable AC, DC or AC+DC power source. It also incorporates an advanced digital signal processor based data acquisition system that continuously monitors all AC source and load parameters.

This data acquisition system forms the basis for all measurement and analysis functions. These functions are accessible from the front panel and the remote control interface for the MX Series (MX15 excluded; uses 2-line display shown below).

Common AC and DC measurement parameters are automatically provided by the data acquisition system. These values are displayed in numeric form on the front panel LCD display. The following measurements are available:

Frequency, V rms, Irms, Ipk, Crest Factor, Real Power (Watts), Apparent Power (VA) and Power Factor.

The measurement system is based on real-time digitization of the voltage and current waveforms using a 4K deep sample buffer. This time domain information provides detailed information on both voltage and current waveshapes. Waveform acquisitions can be triggered at a specific phase angle or from a transient program to allow precise positioning of the captured waveform with respect to the AC source output.

The front panel LCD displays captured waveforms with cursor readouts (excluding MX15). The included GUI program also allows acquired waveform data to be displayed, printed, and saved to disk.
