The global market for AC power testing demands for more sophisticated, high performance AC power source that is capable of simulating a wide range of AC line conditions. Chroma 61500/61600 series programmable AC source are the right solution to meet the market requirements by providing the ability to simulate various AC line input conditions and measurement of critical characteristic for products under test. These features make the 61500/61600 series ideal for commercial, power electronics, avionics, military and regulation test applications from bench-top R/D design veri-cation, quality assurance to mass production.

Using the state of the art PWM technology, the models 61511/61512/61611/61612 can deliver the maximum output voltage up to 300Vac and output frequency from 15Hz to 1500Hz. The AC+DC modes extend the applications not only for providing pure AC voltage, but also DC component for DC oset testing in laboratory.

The 61511/61512/61611/61612 AC sources are capable of delivering up to 4 times of peak current compared to its maximum rated current that makes it ideal for inrush current test. All models possess the ability to generate pure sine waveform output with typical distortion less than 0.3% at 50/60Hz.

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, model 61511/61512 can easily simulate power line disturbance (PLD) by LIST, PULSE and STEP modes.

Chroma 61500/61600 series allow users to compose different harmonic components to synthesize various harmonic distorted wave forms. By applying this advance feature, users can program a sweeping frequency component incorporate with fundamental voltage for finding the resonance points of UUT, thus provide user with in depth analysis result.

To simulate the natural wave form, the 61500/61600 series provide an external analog input to amplify the analog signal generated from arbitrary signal generator. Thus, user can implement this feature to duplicate the unique waveform observed in the field.

ADVANCED PWM TECHNOLOGY

Chroma 61500/61600 series AC power source are able to provide highest power density by its advanced high speed PWM mode design. The modularized power stage design offer outstanding performance and high reliability. The modularized design allows service personnel to identify the trouble spot more efficiently and minimize the downtime. With no transformer at the output stage, it not only reduces the output impedance, but also lets 61500/61600 series be able to program DC component for simulating AC voltage with DC offset condition. This function allows user to simulate the test condition of unbalanced input current for rectified load.

SINGLEPHASE AND THREEPHASE OUTPUT

Model 61511/61512/61611/61612 AC sources are capable of delivering single or three-phase output depending on the user's application. Users can select these output modes easily through front panel or via remote control. Model 61511/61512/61611/61612 AC sources are able to provide full power output without derating even with the output is configured as single phase.

SLEW RATE SETTING FOR VOLTAGE AND FREQUENCY

Model 61511/61512/61611/61612 AC sources let users set the slew rate of voltage and frequency. It will follow the slew rate to reach the final setting when the output voltage or frequency is changed. This function can help the users to verify the operation range of input power. For example, user can implement this feature to sweep the voltage gradually from 90V to 264V instead of only checking several points like 90V, 115V, 230V and 264V. Another application is; in order to reduce the inrush current during motor startup or power on multiple UUT, the user can decrease the slew rate setting to achieve the objective.

AC SOURCE MASTERSLAVE PARALLEL OPERATION

The 61511/61512/61611/61612 AC source models provide the (Master-Slave) parallel operation function, which enable users to extend the AC source power output ability by connecting AC sources in parallel. The maximum allowable number of AC source implemented for the parallel operation is 5 units. Therefore, users can achieve a maximum power output up to 90KVA by combining 5 units of assorted AC source of 18KVA in (Master-Slave) parallel operation mode. The user could also use A615103 Power Stage as an alternative cost effective solution for the parallel operation, by implementing it as slave unit. Please refer to the following figures for AC source models 61511/61512/61611/61612 setup for parallel operation configuration.

THE 61500/61600 SERIES SOFTPANEL*

Chroma Softpanel is a graphical user interface which provides extraordinary capability and convenience to user for delivering control to the unit. The 61500/61600 series Softpanel is designed specifically for offering users to control the AC source by applying user friendly interface configured in a graphical, instrument like settings. The self explanatory graphical interface makes the enabling of extensive functions of AC source with just few clicks of button. Users are able to perform online and offline waveform editing with the implementation of Softpanel. The Softpanel is also equipped with data recording function as multiple measurement data can be recorded simultaneously. One of the most powerful features for Softpanel is the availability of test environment configured specifically for conducting IEC regulation test, such as IEC 61000-4-11(Pre-complience), IEC61000-4-13, IEC61000-4-14 and IEC61000-4-28.

* Softpanel support functions are actually depending on the AC Source model being implemented. For instance, Softpanel will not provide support for LIST mode function if 61600 series AC Source is implemented.
