Performance. Reliance. Brilliance.

Inspired by the enduring power of a brilliant star, the California Instruments "Asterion" line of AC power sources by AMETEK Programmable Power combines intelligence and flexibility to create an advanced platform of AC solutions. This easy-to-configure design features sophisticated technology for delivering high performance, programmable AC and DC power. Its sleek design packs maximum power density into a low-profile form factor with an intuitive touch screen interface placing that power at your fingertips. Centralized control and unparalleled modularity make Asterion the most adaptable platform on the market. Its ground-breaking capabilities set the standard for affordable, precision power sources.


iX2™ current doubling technology.

All Asterion sources employ AMETEK’s latest current enhancing technology, iX2™. The iX2 current doubling technology enables output current to increase linearly up to two times the full voltage current as the voltage decreases from range maximum to one-half of range voltage. iX2 technology results in a source that delivers full power over the widest voltage ranges. This eliminates the need to buy overpowered sources just to reach low line current requirements.

Control via Front Panel Touchscreen & Encoder or available digital control interfaces

The Asterion AC Series can be operated from the intuitive, easy to use front panel touchscreen or the Ethernet LXI, USB and RS232 standard control interfaces, as well as through the optional GPIB control interface The touchscreen function group icons include a Dashboard, Output Programming Parameters, Measurements, Sequencing, Configuration, Control Interfaces, Applications, and System Settings. Function selection and parameter entry can be achieved either by direct selection from the touchscreen or by using the encoder selector button. The control resolution is adjusted by a dynamic rate change algorithm that combines the benefits of precise control over small parameter changes with quick sweeps through the entire range.


Applications

The Asterion AC Series is designed for testing today’s complex electronics, including avionics, telecommunications and commercial electronics requiring low profile, light weight power sources with high power density. Other applications include:

  • Commercial and military avionics test
  • AC power simulation
  • Manufacturing and process control
  • Frequency & voltage conversion
  • IEC standards testing
  • ATE applications


Asterion AC Virtual Panels (Graphical User Interface)

Virtual Panels allow remote control of the Asterion AC power source, as well as programming communication and monitoring for the Asterion ATE model, without front panel display.




The Asterion Series is available in an ATE (Automated Test Equipment) version without front panel, manual controls.

When purchasing a power supply, the first choice to be made is linear supply or switching supply. Linear power supplies offer low ripple and noise specifications and have fast transient behavior. However they are inefficient and generate a lot of heat. They are also quite heavy. As a result most engineers prefer linear power supplies for low power applications. Using switching power supplies is a better choice for higher output power or multichannel applications. They provide higher power density. Switching power supplies are easier to control than linear supplies and cost about the same per channel.

DC output voltage slew rate is a rise or fall time. DC programmable power supplies have output filters that use large capacitors that store a lot of energy. It’s mainly the charge and discharge time of this filter, combined with the current demand of the DUT, which determine a supply’s voltage slew rate. The voltage slew rate is mostly independent of the connected EUT.

Stability is a measure of a supply’s long term output voltage or current drift. Stability is primarily specified in parts per million or ppm.

If more output current is required then paralleling power supply outputs is generally the solution. Ametek Programmable Power uses a dedicated control bus to connect its power supplies in parallel. The system configures itself automatically, identifying which unit is the master and which units are the slaves.

If more output voltage is required then connecting power supplies outputs in series is generally the solution. All you have to do is to connect the positive terminal of one supply to the negative of another. The limitation is that when operated in series, there are no master and slave units. Individual power supplies has to be programmed.

Upgrading to the Asterion power supply system has given us significant more testing capability and flexibility. It has been a wise investment. Thank you for your advice and support.

TEST LABORATORY SENIOR ANALYST AT UNIVERSITY OF NSW

Buying the MX45 California Instruments power source has given us enhanced testing capabilities. We have the SNK option, which is a bidirectional sink option. We are now able to simulate all grid conditions in our lab environment up to 45kVA. For me, reliability is important and I’m happy to say that we have been using this device for many years without any issues.

RESEARCH FELLOW AT UNIVERSITY OF WOLLONGONG

We have several Sorensen power supplies in our lab and they are the lowest output noise power supply we have experienced. For any critical research project where output noise and line/load regulations are important, we use only Sorensen power supplies.
