Rent Chroma 61704 3-Phase AC Power Source for MIL-STD-704 and RTCA DO-160 Testing

The Chroma model 61704 Programmable AC source 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. It delivers the right solution to simulate all kinds of input condition of UUT to be utilized in R&D and QA. It is also suitable for commercial applications from laboratory testing to mass productions.

The 61700 series AC Source supplies the output voltage from 0 to 300VAC and it can be set individually for each phase. Users also can set the phase angle from 0° to 360°. These kinds of function make the 61700 series can simulate unbalance 3-phase power. Because of the wide output frequency from 15 to 1200Hz, it is suitable for avionics and military application. The AC+DC mode extends the output function to simulate abnormal situation when power line contains DC offset.

The 61700 series uses the state-of-the-art PWM technology and power factor correction circuit. So it is capable to generate very clean AC output with typical distortion less than 0.3%, and it can yield higher efficiency and deliver more output power.

By using advanced DSP technology,the 61700 series offers precision and high speed measurements such as RMS voltage, RMS current, true power, power factor, and current crest factor, etc.

The 61700 series offers an optional function to output transient voltage. The function includes LIST, PULSE, STEP and INTERHARMONICS mode. Users can easily program variant waveform for immunity test. The 61700 series can also be controlled by a powerful and user-friendly softpanel through GPIB or RS-232 interface. Besides that, the softpanel includes a waveform editor that can edit up to 40th order harmonic components. By this way, the 61700 series get the ability to output distorted waveform as users like.

The self-diagnosis routine and protections against over power, over current, over voltage, over temperature and fan fail, the 61700 series ensure the quality and reliability for even the most demanding engineering testing and production line application.

Comprehensive Measurements
By building in a 16-bit precision measurement circuit, the 61704 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 rotary knob to change the measurement items shown on LCD display. They also can change page to see more measurement items.

Slew Rate of Voltage (Optional Function)
The 61704 programmable AC Source uses DSP technology to program voltage waveform. 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. It can help to easily test the line input range of the products, for example 190V-264V. It also can reduce the inrush current if setting the line in voltage increasing from a low level to a high level.
