The global market for AC power testing demands a more sophisticated, high performance, AC power source that is capable of simulating a wide range of AC line conditions. The Chroma 61500/61600 series programmable AC sources are the right solution to meet market requirements by providing the ability to simulate various AC line input conditions and measurements of critical characteristics 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, and quality assurance, to mass production.
Advanced PWM Technology
Chroma 61500/61600 series AC power sources are able to provide the highest power density by utilizing advanced high speed PWM mode design. The modularized power stage design offers outstanding performance and high reliability. The modularized design also allows service personnel to identify trouble spots more efficiently and minimize downtime. With no transformer at the output stage, it not only reduces the output impedance, but also creates the ability for the 61500/61600 series to program DC components for simulating AC voltage with DC offset conditions. This function allows users to simulate test conditions of an unbalanced input current for rectified loads.
Single-Phase & Three-Phase Output
Model 61511/61512/61611/61612 AC sources are capable of delivering single or three-phase output depending on the users application. Users can select these output modes easily through front panel controls or via remote control softpanels. 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. This will follow the slew rate to reach the final setting when the output voltage or frequency is changed. This function can help users verify the operation range of input power. For example, users can implement this feature to sweep the voltage gradually from 90V to 264V, instead of only checking several specific points, for instance 90V, 115V, 230V and 264V. Another application reduces the inrush current during motor startup or power on of multiple UUT, users can adjust the slew rate setting to achieve the objective.
Chroma AC power sources in the 61500/61600 series have 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 advanced DSP technology, the 61500 series can measure THD and up to 40 orders of current harmonics. This makes the 61500 series not only a sophisticated power source but also a powerful analyzer.
Power Line Disturbance Simulation (61500 Series)
In addition to the steady output voltage and frequency programming, Chroma AC power source 61500 series provides powerful functions to simulate all kinds of power line disturbance conditions. The STEP and PULSE modes offer an easy and convenient method to execute a single step or continuous output changes. The changes may be triggered by an internal or external event. With this capability, it’s easy to simulate power line disturbances such as cycle dropout, transient spike, brown out and etc.
The LIST Mode extends this function for more complex waveform generator needs, up to 100 sequences with different start-end conditions, that can perform almost any waveform by AC and DC components. In this way, Chroma AC power source 61500 series is capable of simulating all sorts of voltage dips, interruptions and variation waveforms for IEC 61000-4-11 pre-compliance test and IEC61000-4-14/IEC61000-4-28 compliance tests. It also allows users to synchronize external events as well as measurement devices with output changes.

Distortion Waveform, Harmonics, Interharmonics Synthesis (61500 Series)
Traditional type of AC source only provides output voltage with sine waveform and this type of AC source is unable to meet and keep up with the latest test requirements for simulating the input voltage abnormal condition with distortion waveform. The WAVEFORM function allow user to set square, clipped-sine wave and 30 stored distortion waveforms. Besides that, IEC 61000-4-13 standard requires not only the harmonics waveform, but also interharmonics simulation.
Model 61500 series allow users to composite integer up to 40 orders of harmonic components based on 50Hz or 60Hz fundamental. The output will be a periodic harmonics distortion waveform. It also provides sweeping interhamonics function. This means the fundamental frequency will incorporate with a frequency sweeping component between harmonic frequencies. It can help to find the resonance or the weakest points of UUT. Chroma AC source 61500 series uses advanced DSP technology to synthesize the harmonic and interharmonics waveforms. Therefore, it is capable of generating a periodic harmonic and non-periodic harmonic distorted waveform to perform IEC 61000-4-13 compliance test.
Programmable Output Impedance (61500 Series)
Chroma AC source 61500 series allow users to program output impedance. A current feedback control circuit makes the output voltage changed with the load. This feature is suitable for IEC 61000-3-3 Flicker tests or other test condition with particular output impedance requirement. It provides users a convenient and cost effective way to implement the reference impedance.
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.
