New California Instruments MX22.5 AC/DC Power Source Makes Three-Phase Power More Affordable
- Posted on 04/05/17 10:48PM

SAN DIEGO, May 4, 2017AMETEK Programmable Powerhas added a 22.5 kVA unit to its popular California Instruments MX Series II AC/DC Power Sources. The MX22.5 delivers up to 22.5 kVA and can be configured to have single-phase or three-phase outputs in AC, DC or AC+DC mode. The MX22.5 is more economical than the California Instruments MX30, while at the same time offers more features and higher output power than the product family’s MX15 model.

The California Instruments MX Series II provides controlled AC and DC output for a wide variety of automated test equipment and product test applications at an affordable cost. Using state-of-the-art PWM switching techniques, the MX series combines robustness and functionality in a compact floor-standing chassis, no larger than a typical office copying machine. And, this higher power density does not need elaborate cooling schemes or additional installation wiring. Simply place the unit in its designated location (using included casters), plug it in, and the MX Series is ready to operate.

The MX22.5’s innovative features include:

  • 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.
  • Expandable power levels. Users can combine units to configure systems up to 135 kVA or more.
  • Switching between single-phase and three-phase outputs. Phase mode programming on MX22.5-3Pi allows users to easily switch between single-phase and three-phase output modes.
  • Arbitrary and harmonic waveform generation. Using the latest DSP technology, the MX
  • Series programmable controller is capable of generating harmonic waveforms and arbitrary waveforms to test for susceptibility to harmonics and other power anomalies.
  • Regenerative, bidirectional “green” power. Automatic crossover between source and sink power modes offers regenerative capabilities in AC or DC mode. The power sources can regenerate up to 85% of the rated output power back to the utility grid during sink mode operation when equipped with the -SNK or -SNK-DC option.
  • Power measurements. The MX Series can make a wide variety of measurements in addition to supplying power, including frequency, Vrms, Irms, Ipk, crest factor, real power (watts), apparent power (VA), and power factor. These measurements  are accessible from either the front panel or the remote control interface
  • Remote control. The MX Series can be equipped with RS-232C, USB, IEEE-488, and LAN Interfaces for remote operation and automated test applications.

AMETEK Programmable Power Launches Sorensen HPX Programmable DC Power System for High-Power Applications
- Posted on 14/12/16 08:06PM

SAN DIEGO, December 13, 2016 – AMETEK Programmable Power, the global leader in programmable AC and DC power test solutions, manufacturing such brands as California Instruments™, Sorensen™ and Elgar™ (, has introduced a new DC power system in the Sorensen family ideally suited for high-power applications.

AMETEK’s new Sorensen HPX High Power Extensible DC Series is a highly configurable solution available from 36kW - 240kW+ power levels. The extensible platform delivers unsurpassed quality and reliable low-noise performance, fast and precise programmability with premium features at an affordable price, all in a convenient rack-mount cabinet.

AMETEK has long been known for supplying power sources with leading power performance. The Sorensen HPX series is no exception, with advances in programmability, modularity and low-noise performance.  The HPX features two modes in one: automatic constant voltage and constant current mode crossover.

State-of-the-art, FET-based, high-frequency switching technology offers accuracy, exceptional load transient response and low noise in a smaller footprint as compared to other DC power supplies.  In addition, its modular design protects the integrity of the system components and simplifies sparing and maintenance. 

The Sorensen HPX can accommodate up to 150kW in a single bay rack-mount cabinet, or up to 240kW in a dual bay rack. Additionally, the series includes Remote Sense technology for correcting errors from line voltage drops, and a Remote Shutdown (S/D) Interlock to protect against hazardous faults.

HPX builds on Sorensen’s long history of providing high-quality DC power supplies. The Sorensen HPX series serves every major market and application that requires demanding test specifications from industrial automation and material research to aerospace and satellite testing.

AMETEK Programmable Power Launches Asterion™ AC/DC Power Platform with Current-Doubling iX2™ Technology
- Posted on 11/05/16 10:42PM

SAN DIEGO, May 11, 2016 – AMETEK Programmable Power, the global leader in programmable AC and DC power test solutions, manufacturing such brands as California Instruments™, Sorensen™ and Elgar™ (, has introduced a new AC and DC power platform that establishes new industry benchmarks in power density, performance, and ease of use.

AMETEK’s initial platform launch is for its California Instruments AsterionTM AC Power Source, available in 500VA, 750VA and 1500VA power levels. Asterion relies on a variety of technical innovations that allow it to be one of the most powerful AC sources on the market. Asterion offers users a compelling combination of intelligence, performance, and modularity that make it the most adaptable and affordable platform available today.

AMETEK has long been known for supplying power sources with leading power density. The Asterion is no exception with up to 1500VA in a 1U (44.45mm/1.75in) height package; that is two to three times the power density of comparable, competitive power sources.

At the heart of Asterion’s breakthrough performance is AMETEK’s powerful new iX2™ current-doubling technology. With iX2, as the output voltage decreases from maximum to one-half maximum, Asterion’s available output current increases up to two times the 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's power performance specifications are equally impressive. For example, 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 the Asterion more accurate than most other AC power sources on the market.

Furthermore, test engineers will appreciate the Asterion 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, the Asterion 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.
