DC, 15~1.2kHz

The Chroma Programmable AC source 61700 series delivers pure, 5-wire, 3-phase AC power. Unlike the traditional 3-phase AC source, it includes low power rating models at very low cost. Users can program voltage and frequency, measure the critical characteristics of the output on its LCD display; thus delivering the right solution to simulate all kinds of input condition of UUT to be utilized in R&D and QA.

Comprehensive Measurements

By building in a 16-bit precision measurement circuit, the 61700 series AC source offers precision and high speed measurements such as RMS voltage, RMS current, true power, power factor, and current crest factor, VA (apparent power) and VAR (reactive power). Users can use the rotary knob to change the measurement items shown on the LCD display, as well as change pages to see more measurement items.

Slew Rate of Voltage

Chroma 61700 series use DSP technology to program voltage waveform. Users can change the voltage in only one step. Users can also set the slew rate to get a gradual increase or decrease of voltage to easily test the line input range of the products, for example 190V-264V. It can also reduce the inrush current if setting the line in voltage to increase from a low level to a high level.

for Operation

The 61700 series AC Source supplies output voltages from 0 to 300VAC and can be set individually for each phase. Users can set the phase angle from 0° to 360°. These 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.
