By building in a 16-bit precision measurement circuit, the 61700 series AC source offers precision and high speed measurements.

The Chroma Programmable AC Power Source model 61700 series delivers pure, 5-wire, 3-phase AC power. Unlike traditional 3-phase AC sources, it includes low power rating models at very low cost. Users can program voltage and frequency, and measure the critical characteristics of the output on its LCD display. It provides the ability to simulate all kinds of UUT input conditions to be utilized in R&D and QA. It is also suitable for commercial applications from laboratory testing to mass production.

Such as RMS voltage, RMS current, true power, power factor, and current crest factor, VA (apparent power) and VAR (reactive power).

The 61700 series AC Source supplies output voltages from 0 to 300VAC and can be set individually for each phase. Users also can set the phase angle from 0° to 360°. These kinds of functions allow the 61700 series to simulate unbalanced 3-phase power. With a wide output frequency range, from 15 to 1200Hz, it is suitable for avionics and military applications. The AC+DC mode extends the output function to simulate abnormal situations when the power line contains a DC offset.

Users can change the voltage in only one step. Or users can set the slew rate to get a gradual increase or decrease of voltage.
