Today’s power conversion testing demands programmable, high performance AC sources capable of simulating a wide range of AC line conditions. Chroma 61500 series programmable AC sources are the right solutions to meet complex single and three phase requirements due to their precise simulation of AC line conditions and measurement of critical product characteristics during testing. These features make the 61500 series ideal for commercial, power electronics, avionics, and regulation test applications from bench-top R/D design verification and quality assurance to mass production.

Using state of the art PWM technology, all models are equipped to generate pure sine waveform output with typical distortion of less than 0.3% at 50/60Hz. In addition, the Chroma 61500 series are able to provide precision measurements such as RMS voltage, RMS current, true power, power factor, current crest factor, and others. By applying the advanced DSP technology, all models can easily simulate power line disturbance (PLD) by LIST, PULSE, and STEP modes.

The Chroma 61500 series allow users to create 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 natural waveforms, the Chroma 61500 series provides 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 61500 series AC sources’ functions through a large graphic LCD display front panel with an easy to use keypad. GPIB (IEEE488.2), RS-232, USB, and Ethernet interfaces are available to control the AC source remotely.
