The global market for AC power testing demands a more sophisticated, high-performance AC power source capable of simulating a wide range of AC line conditions. To meet these demands, Chroma has developed a high power density, low form factor, (5U) instrument. The Chroma 61509/61508/61507/61609/61608/61607 models are the latest of the 61500/61600 series AC source.

The Chroma 61500/61600 series programmable AC sources are the right solutions to meet complex single and three-phase requirements due to their ability to simulate AC line conditions and measure critical product characteristics during testing. These features make the 61500/61600 series ideal for commercial, power electronics, avionics, military, and regulation test applications from bench-top R/D design verification and quality assurance to mass production. DC functionality enhancements, with DC power ratings of up to 75% of full output power, has further extended test application capabilities, especially for AC/DC server PSU.

Using state-of-the-art PWM technology, the 61509/61508/61507/61609/61608/61607 models deliver maximum output voltage of up to 350Vac and output frequency of 15Hz to 2000Hz. All models possess the ability to generate pure sine waveform output with a typical distortion of less than 0.3% at 50/60Hz.

The Chroma 61500/61600 series are able to provide precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor, and so on. By applying the advanced DSP technology, the 61509/61508/61507 models easily simulate power line disturbance (PLD) by LIST, PULSE, and STEP modes.

The Chroma 61500 series allow users to compose different harmonic components to synthesize various harmonic and distorted waveforms. By applying this advanced feature, users can program a sweeping frequency component incorporated with the fundamental voltage for finding the resonance points of the UUT, thus providing users with in-depth analytical results.

To simulate the natural waveforms, the Chroma 61500/61600 series provide an external analog input to amplify the analog signal generated by an arbitrary signal generator. Thus, users can implement this feature to duplicate unique waveforms observed in the field. The user-friendly interface allows for quick access to the 61509/61508/61507/61609/61608/61607 AC sources' functions through a large graphic LCD display front panel with an easy to use keypad. The GPIB, RS-232, USB, and Ethernet interfaces are available to control the AC source remotely.

Comprehensive Measurements

Chroma AC Power Source 61500/61600 series have built-in 16-bit measurement circuits and ?rmware utilities to measure the true RMS voltage, current, true power, apparent power, reactive power, power factor, current crest factor, repetitive peak current, and inrush current. Using advanced DSP technology, the 61500 series can measure THD and up to 50 orders of current harmonics. The 5.7" Color LCD provides users with easy to operate interface by integrating parameters and functions on a single display page. The panel is also capable of voltage and current measurement waveform display.

Power Line Disturbance Simulation (61500 Series)

In addition to the ability to program steady output voltage and frequency, The Chroma 61500 series provides powerful functions to simulate all kinds of power line disturbance conditions. The STEP and PULSE modes offer easy and convenient methods to execute a single step or continuous output changes. The changes may be triggered by an internal or external event. This allows for an easy simulation of power line disturbances such as cycle dropout, transient spike, brownout, etc. The LIST mode extends this function for more complex waveform generator needs of up to 100 sequences with different start-end conditions that can perform almost any waveform by AC and DC components. The Chroma AC power source 61500 series is also capable of simulating all sorts of voltage dips, interruptions, and variation waveforms for IEC 61000-4-11 pre-compliance tests and IEC61000-4-14/IEC61000-4-28 compliance tests.
