Asterion AC Power Sources
The Future of AC Power Sources
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.

Sorensen Lab DC Power Supply Extends Capabilities with PowerFlex Switch-Mode Technology
The new XPF60-20S unit is a single output version of the dual output XPF60-20D. It provides up to 60V and 20A within its 420W power envelope, all in a one quarter rack width x 3U height that uses the minimum possible space for either bench or rack mounting. Since the XPF60-20S has manual control, it will most often find use in conventional bench-top use. The Series, which offers both analog and digital control, features easier-to-use analog controls without sacrificing digital stability.
The Sorensen XPF60-20S and 20D outperform competitive units due to Sorensen’s PowerFlex switch mode technology design. PowerFlex switch-mode technology generates higher currents at lower voltages within an overall power limit envelope. This is an advantage over traditional power supplies that have a fixed current limit for a power capability that reduces directly with the output voltage.
Users also can select from two other variants of the single output version of the XPF60-20 Series. The XPF60-20SA includes fully galvanically isolated, voltage driven remote control for both voltage and current, while the XPF60-20SP provides duplicate rear terminals and digital remote control. Completing the XPF60-20 Series line, the XPF60-20DP dual output model adds digital remote control. Both dual output models also have small footprints so they take up less space on a crowded bench. All XPF60-20 Series units offer connectivity via GPIB, RS-232, USB, LAN and LXI Class C.
Additionally, the XPF60-20S DC power supply offers both Constant Voltage (CV) and Constant Current (CC) operation with automatic cross-over. The unit offers good transient response, built-in power factor correction, and both load and line regulation. The XPF60-20S DC also offers low ripple and noise — for example at 20MHz bandwidth, typically <2mV rms, <10mV pk-pk, (4mV rms maximum), CV mode. Outputs are forward protected by an over-voltage protection (OVP) trip and reverse protected by diode clamp. Users can easily change the OVP range with a screwdriver adjustable preset on the front panel.
The line’s XPF60-20D model is a dual output DC power supply with two completely independent and isolated outputs. The outputs can be wired in series or parallel to achieve up to 120V or 40A within a total power envelope of 840W. Users can set voltages with coarse and fine controls and set currents by a single logarithmic control. An S-Lock (Settings Lock) switches between voltage and current settings and locks them in with a press of the button. This ensures that settings don’t drift over time or are accidently changed.
Also, as an alternative to the unit’s PowerFlex operation, a fixed range mode lets the power supply work as a conventional power supply with fixed ranges of either 60V/7A or 20V/20A at the press of a button. This ensures the output can only be in CV or CC mode and never in power limit, whatever the load. Another button in the fixed range mode lets users customize voltage and current limits to exactly suit their application.

AMETEK ADDS DC REGENERATIVE SINK OPTION CAPABILITY
AMETEK Programmable Power, the global leader in programmable AC and DC power test solutions (programmablepower.com), has added the ability to sink DC current to its California Instruments’ RS and MX Series Power Sources
The addition of this option to an RS or MX Series power source with AC Sink installed allows users to source and sink both AC and DC currents at up to 100 percent of the source’s rated output power. When sinking current, the current is regenerated and returned to the electrical grid reducing the operating cost of electricity.
There are many applications for sinking AC current, such as the prevalent need to regenerate current back to the electrical grid while testing grid-tied inverters. A common DC sink application, among others, is to simulate batteries connected to a bidirectional converter in hybrid electric vehicle motor drive systems.
When purchasing a new RS or MX Series power source, customers can purchase the SNK option to sink only AC current, the SNK-DC option to sink only DC current, or both options for ultimate versatility. Upgrading an existing RS unit can be done by AMETEK, depending on the age of the unit. Consult factory for further details.

AMETEK Programmable Power, the global leader in programmable AC and DC power test solutions, has expanded its industry-leading Elgar Terrestrial Solar Array Simulators (TerraSAS™) line of standalone photovoltaic (PV) simulators.
With the newest Embedded TerraSAS™ (ETS), users can now test isolated and non-isolated string inverters with voltages (Voc) up to 1,000 VDC and currents (Isc) up to 15 A, resulting in a 50% increase in output power compared to the prior 1000X ETS model. The new ETS1000Y is available in three configurations: [5kW] 1,000 VDC @ 5 A, [10kW] 1,000 VDC @ 10 A and [15kW] 1,000 VDC @ 15 A.
The TerraSAS™ PV simulator consists of an agile high-performance, programmable DC power supply with control software and GUI interface, high output isolation, and a unique embedded PV simulation engine that provides the I-V curve in a single standalone unit. The power supplies in the TerraSAS™ PV simulators are typically ten times faster than standard power supplies, allowing users to test even the most advanced solar inverters.
In addition to this industry-leading performance, the new ETS now offers improved Over-Voltage Protection (OVP) and Over-Current Protection (OCP). This allows the device to be used for sensitive simulation applications without tripping, such as inverter testing in electrically “noisy” environments.
AMETEK Programmable Power developed the TerraSAS™ line for testing microgrids, energy storage and inverter test applications. The TerraSAS™ series photovoltaic (PV) simulators are specifically designed to emulate the dynamic electrical behavior of a terrestrial PV solar array. They offer low output capacitance and high closed loop bandwidth to keep up with the advanced Maximum Power Point Tracking (MPPT) algorithms used in today’s grid-tied inverters.
The new ETS versions can be configured to use a 3-phase AC input voltage of 187-242 VAC, 342-440 VAC, or 396-528 VAC. Output voltage noise is less than 0.6 Vpp, and output current noise is less than 200 mApp.
