Regenerative Source and Load with PHIL Interface Capability

The AZX Series is an all-in-1 regenerative 4-quadrant AC and DC power source that can function as an AC voltage source, DC power supply, current source, AC/DC load, and PHIL Interface. The AZX’s high power density provides 30kVA/kW up to 55kVA/kW in a single cabinet and can parallel up to 550kVA/kW. This comprehensive platform is optimized for PHIL, has three powerful DSPs to cover advanced applications, and eliminates the need for add-on equipment.

All-in1 Multi-Functional AC DC Power Source

The Regenerative AC/DC Power Source AZX Series simulates almost any power disturbance and distorted waveforms. The AZX Series is cost effective and fully programmable for both basic frequency conversion and advanced AC power line or DC power disturbance test applications requiring up to 1000 Hz fundamental frequency. The energy recovery capability allows both sourcing and sinking of current and power up to 100% of rated power. Adding the Load Option (Option L) adds full electronic regenerative AC & DC Load programming capability to the AZX while Option H provides high speed analog I/O for PHIL.

Test applications: Aerospace power and compliance testing, Utility grid, microgrid, EV chargers, Vehicle-to-Grid (V2G), Vehicle-to-Home (V2H), Solar PV/grid-tied inverters, home energy storage systems, UPS, PDUs, test laboratories, and more. 

Applications range from simple, manually controlled frequency conversion to IEC power line emission and immunity testing and with sophisticated transient simulation and PHIL applications.

Modular Power up to 550kVA/kW with Dual Constant Power Voltage Range

The AZX series supports both low and high volrtage ranges for AC or DC. Test accurately with seamless transition of voltage ranges. The constant power voltage range for both higher current at lower voltage and higher voltages at lower currents eliminating the need to switch between voltage ranges. This prevents potential disruptions in output power.

Mobile-friendly, parallelable cabinets make it easy for set up and reconfiguration.

• Increase power when needed to meet future test requirements.
• Reduced downtime. Modularity increases up time during service and maintenance of individual cabinets. 
• Top air-cooled vents allow the units to be placed against a wall or back-to-back to maximize floor space.

Power Hardware-in-the-Loop with High-Speed Analog I/O

The AZX Series provides integrated test system design with a standard suite of analog and digital I/O functions. The user can assign command macros or setting parameters to analog or digital I/O pins as needed. This provides a unique level of customization for putting together sophisticated test stations.

While analog inputs and outputs are standard on all AZX modes, for real-time Power Hardware in the Loop (HIL) Grid simulation applications, the AZX offers an optional high speed set of analog inputs and outputs with fast output response. By adding the H Option, the AZX can be used as an amplifier for PHIL Applications. This analog interface provides high speed input for controlling frequency, voltage or current and waveshape. Voltage and Current output capture signals are returned to the Real Time Simulation System.

Flexible Output Configuration for Testing Wide-Range of Conditions

Simultaneous AC and DC operation of modes per phase(or channel), and the automatic switching of output modes provides test engineers with a unique capability and the highest degree of flexibility. AC, DC, (AC+DC optional) output configurations are available in single, split, three phase and multi-channels with optional isolated neutrals in AC and DC.

Full galvanic isolation from facility AC input to output and between output phases/channels also protects the user and the UUT.  

Easily Generate Harmonics & Inter-Harmonic Waveforms

The Regenerative AC DC Source – AZX Series has a built-in waveform digitizer and scope with fast transient capabilities at 100us time resolution supporting LIST, PULSE and STEP modes. Waveform generation includes ten Standard, Sine, Square, Triangle, Clipped and Harmonics (and inter-harmonics option).
