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.
Using state of the art PWM technology, the 61511/61512/61611/61612 models can deliver a maximum output voltage of up to 300Vac and an output frequency from 15Hz to 1500Hz. The AC+DC modes extend the abilities by not only providing pure AC voltage, but also a DC component for DC offset testing in the laboratory
The 61511/61512/61611/61612 AC sources are capable of delivering up to 4 times the peak current compared to the maximum rated current which makes it ideal for inrush current tests. All models possess the ability to generate a pure sine waveform output with 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 more. By applying advanced DSP technology, the 61511/61512 models can easily simulate power line disturbance (PLD) through LIST, PULSE and STEP modes.
The Chroma 61500/61600 series allow users to compose different harmonic components to synthesize various harmonic distorted waveforms. By applying this advanced feature, users can program a sweeping frequency component incorporated with the fundamental voltage for finding resonance points of the UUT, thus providing the user with in depth analysis results.
To simulate the natural waveform, the 61500/61600 series include an external analog input used to amplify the analog signal generated from an arbitrary signal generator. Users can implement this feature to duplicate any unique waveform observed in the field.
The user friendly interface allows user quick access to the 61511/61512/61611/61612 AC source’s functions through a large LCD display on the front panel, with a clearly indicated keypad. GPIB (IEEE488.2), RS-232, USB, and Ethernet interfaces are available for remote control of the AC source.
