Integrated System
The FCS Series II AC Power system is one of the most power systems in the industry, supporting high power levels with ease, at a reduced cost. The FCS Series II combines a flexible AC power source with a harmonic power analyzer that is capable of handling the most complex applications.
The FCS Series II uses a state-of-the-art Digital Signal Processor in conjunction with precision A/D converters. This provides more accuracy and resolution for test applications then is found in most dedicated harmonic power analyzers.
This system integrates digital multimeters, power harmonics analyzer, and current shuts,
eliminating the need for multiple instruments; thus reducing cost and providing more
flexibility than can be found with competing products.

Easy To Use Controls
The FCS Series II is microprocessor controlled and is operated using the front panel keypad that makes precise entries simple, and our powerful Instrume Control Software which offers an even higher level of programability. An analog control allows output voltage and frequency to be slewed up or down dynamically. The control employs a dynamic rate change algorithm that combines the benfits of precist control over small parameter changes with quick sweeps through the entire range.

Applications
With precise output regulation and accuarcy, high load drive current, multi or single phase mode, and built-in power analyzer measurement capabilities, the FCS Series II Power System addresses many application areas for AC power testing. Additional features like line arbitrary waveform generation, DO 160, MIL 704, and Airbus test standards make the FCS Series II a great choice for avionics and defense applications.

Measurement and Analysis
Standard Waveforms
The FCS Series II Series provides three standard waveforms that are always available for output. The standard waveforms are:
• Sinewave for normal AC applications.
• Squarewave for special applications.
• Clipped Sinewave - Simulates THD levels to test for harmonic distortion susceptibility.
In addition to these standard waveforms, user defined waveform can be downloaded over the bus.

Harmonic Waveform Generation
Using the latest DSP technology, the FCS Series II Series controller is capable of generating harmonic waveforms to test for harmonics susceptibility of a unit under test. The Instrument Control Software can be used to define harmonic waveforms by specifying amplitude and phase for up to 50 harmonics. The waveform data points are generated and downloaded by the Instrument Control Software to the AC source through either the Remote Interface bus and remain in nonvolatile memory. Up to 50 waveforms can be stored and given a user defined name for easy recall.

The three phase FCS Series II configuration offers independent waveform generation on each phase allowing three phase anomalies to be programmed and also allows simulation of unbalanced
line conditions.

Arbitrary Waveform Generation
Using the provided Instrument Control Software, the user also has the ability to define arbitrary AC waveforms. The arbitrary waveform method of data entry provides an alternative method of specifying AC anomalies by providing specific waveform data points. The Instrument Control Software includes a catalog of custom waveforms.

Arbitrary waveform capability is a flexible way of simulating the effect of real-world AC power line conditions in both engineering and production environments.

Configuration Options
AC Transient Generation
The FCS Series II controllers have a powerful AC transient generation system that allows complex sequences of voltage, frequency and waveshapes to be generated. This further enhances the capability to simulate AC line conditions or disturbances. When combined with the multi phase arbitrary waveform capabilities, the AC output possibilities are truly exceptional. In three phase system configurations, transient generation is controlled independently yet time synchronized on all three phases. Accurate phase angle control and synchronized transient list execution provide unparalleled accuracy in positioning AC output events.

Transient programming is easily accomplished from the front panel or software where clearly laid out menu’s guide the user through the transient definition process. This feature allows for transient execution, Start, Stop, Abort and Resume operations.

User defined transient sequences can be saved to nonvolatile memory on on the PC for instant recall and execution at a later time. The included Instrument Control Software supports transient definitions using a spreadsheet-like data entry grid. A library of frequently used transient programs can be created on disk.
