AZX Series of Regenerative AC and DC Power Sources

AZX Series

3500AZX parallel source

Are you seeking ways to conserve grid power—and thereby save money—in your equipment testing operations? Of course you are! The AZX Series, therefore, may be just what you’re looking for.

The AZX Series is a family of high-power, single-, split- and three-phase, AC, DC and AC+DC output capable power sources with full energy recovery to the AC mains when sinking power from the equipment under test. Think about that: full energy recovery. That’s a clear strategy for conserving grid power and saving money.

The AZX Series

AZX Series models range from 30-100 kVA. Using a modern color touch screen based user interface for ease of use, 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.

Key applications of the AZX Series

Regenerative grid simulation applications

Demand for renewable energy is growing rapidly, as is the need to test AC and DC products and systems that can recycle energy back to the grid. Regulatory and performance test requirements of these systems require an AZX power source for grid simulation. With extensive control over voltage, current, frequency, phase angles and transients, the AZX series supports testing of solar inverters (PV), energy storage systems (ESS), EV batteries and traction systems, as well as on-line UPS equipment with both AC and DC source and sink capabilities.

Regenerative grid

Avionics and defense power test applications

The AZX Series has a wide output frequency range, allows their use in avionics and defense power applications requiring either 400Hz fixed or 360Hz to 800Hz wild frequency output. For emerging battery backed DC avionics power systems, multiple 270Vdc outputs can be used to simulate a split 540Vdc aviation DC power bus. High-power, three-phase configurations are available to meet regenerative or conventional power test demands. As needs change over time, additional units can be added easily to keep up with your test needs while protecting your original investment.

TDK Lambda SFL DC Electronic Load Series

TDK Lambda’s SFL DC Electronic Load Series was developed to provide an electronic load for the design, evaluation and manufacture of regulated DC power supplies, fuel cells, solar cells, batteries and components. Sales of the series commenced in July 2020.

Key features of the SFL DC Electronic Load Series

  • The SFL series is multi-functional, programmable and offers power levels of 300W (3U half rack) and 1000W (3U full rack) with high-speed response and stable operation at low voltage. The series also offers seven load operating modes that allow the user to connect and test products under various operating conditions.
  • There are two different dynamic operating modes: Dynamic Frequency Mode (allows the user to switch the load between two different settings for a single pulse or repeating pulse profile); and Dynamic Time Mode (allows the user to program up to 16 load settings that can be programmed for a repeating pulse profile). Both modes also provide a rear panel TRIG OUT function for waveform scope viewing or for synchronization with other test equipment.
  • A Sequence function is built-in where simple/complex waveforms can be created (up to 1024 time steps) using Excel-based control software and digital interface communication (USB or IEEE). A Sweep Mode feature is also available, allowing for product testing where devices/products require test sweeps in CR mode for V-I characteristic testing, CC mode for overcurrent protection characteristic testing or CP for overpower protection characteristic testing.
  • The SFL series has a V Mode function that automatically changes the load mode (when voltage is rising or falling) or turns off the load input until the load voltage reaches a set value, on-board memory for storage/recall of up to eight operational settings and a rear panel Remote Sense selection switch and connection ports for connection and voltage measurement across the test device.
  • Model functions can be set up via the 3.5” color LCD front panel display (which has oscilloscope-like function keys on the vertical and horizontal borders). Using these keys in combination with the four embedded operating allows for adjustment, setup, storage and recall of the load operating parameters. These model functions are also accessible via the built-in USB interface or the optional IEEE Interface.
  • Higher power DC load systems (up to 10kW) are achievable using a Master-Slave unit arrangement and a simple parallel cable connection from unit-to-unit, with all system control and monitoring performed through the master unit (for easy interfacing).
  • Multi-channel synchronous operation (with triggering) is also available and allows multiple DC electronic loads to be connected to separate devices by using the same parallel cable connection from unit-to-unit. Synchronized load ON/OFF and Dynamic operation are featured in a Master-Slave configuration with up to ten units (up to 10kW total).
  • Optional interfaces offered include the IEEE Interface (with a built-in DIDO Interface) and the Ripple Measurement Module (R ) Interface. The IEEE Interface is 488.1 compliant with instrument software drivers available for use. The DIDO  Interface allows for remote interfacing with PLC controllers and includes isolated control and status of load ON/OFF, Range setting, Alarm Detection/Clear and Sweep Function Pass/Fail status.
  • Models are available in 300W and 1000W power levels with Output voltages of 120V (60A and 180A) and 500V (18A and 36A) and are powered from a universal single-phase AC input (85~264VAC, 47~63Hz).
