An initial AC and DC power platform launch from AMETEK is for its California Instruments AsterionTM AC Power Source, available in 500VA, 750VA and 1500VA power levels. It is available from TTi. The Asterion offers up to 1500VA in a 1U height package. At its heart is AMETEK’s powerful new iX2 current-doubling technology.
With iX2, as the output voltage decreases from maximum to one-half maximum, the platform’s available output current increases up to two timesthe rated output current. That allows Asterion to maintain maximum power throughout the voltage range, making it unmatched in delivering full output power over such a wide voltage range.
In addition, iX2 current-doubling technology eliminates a common need to buy multiple sources or overpowered sources to run tests at different voltage levels, such as when performing low line voltage testing.
Other unique platform benefits are Auto-Paralleling and Clock/Lock to achieve higher output power and multi-phase configuration. Users can combine up to six units to achieve 9,000 VA per phase of output power.
One unit becomes the master while the rest serve as auxiliary units. System setup can be accomplished using a single front panel or digital interface. Multi-phase systems can be configured for split-phase, three-phase, or even higher phase count requirements.
Users are able to purchase only the power they need today and easily add more power and/or phases later as required. That scalability, along with the ability to expand easily as required, helps protect the value of the initial investment and allows additional capital spending to be deferred until needed.
The Asterion offers wide AC and DC output voltage ranges with an accuracy of +/-0.2% from DC to 1 kHz. Load and line regulation are +/-0.025% and +/-0.015%, respectively, making it more accurate than most other AC power sources on the market.
Furthermore, test engineers will appreciate the AC source’s ease of use, which is based on an entirely new user interface developed by AMETEK specifically for the platform. The intuitive, touch-screen interface, unique on an AC source, allows users to quickly and easily set up the source and run tests.
Asterion is at home both in the lab and in automatic test systems. When used in an ATE system, it can be ordered without a front panel, at a significant savings, and be equipped with LAN, USB, and RS-232 interfaces bundled as standard.
An optional GPIB interface also is available. Intuitive “virtual panel” control GUI software offered with the instrument makes it easy to set up and operate interactively from a computer.
Included drivers make it simple to integrate the unit into ATE systems. The Asterion’s initial series launch also includes, as an option, a complete avionics test suite.
