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 verification, quality assurance to mass production.
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.
Single-Phase & Three-Phase 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 & 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.
Chroma AC power source 61500/61600 series has a built in 16-bit measurement circuit and firmware utilities to measure the true RMS voltage, current, true power, VA (apparent power), VAR (reactive power), power factor, current crest factor, peak repetitive current and inrush current. Using the advanced DSP technology, 61500 series can measure THD and up to 40 orders of current harmonics. It makes 61500 series not only a sophisticated power source but also a powerful analyzer.
AC Source (Master-Slave) 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.
To save the hassle with arranging the input and output wiring of multiple AC sources connection in parallel operation. Users can select and Implement the Chroma input/output terminal fixture (A615104/A615105) designed specifically to solve the wiring issue.
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, IEC61000-4-13, IEC61000-4-14 and IEC61000-4-28.
