The Chroma 61500/61600 series programmable AC source are the right solutions to meet complex single and three phase requirements due to their ability to simulate AC line conditions and measure critical product characteristics during testing. 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. DC functionality enhancements, with DC power ratings of up to 75% of full output power, has further extended test application capabilities especially for AC/DC server PSU.
Using state of the art PWM technology, the 61509/61508/61507/61609/61608/61607 models deliver maximum output voltage of up to 350Vac and output frequency of 15Hz to 2000Hz. All models possess the ability to generate 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 so on. By applying the advanced DSP technology, the 61509/61508/61507 models easily simulate power line disturbance (PLD) by LIST, PULSE, and STEP modes.
The Chroma 61500 series allow users to compose 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 the natural waveforms, the Chroma 61500/61600 series provide 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 61509/61508/61507/61609/61608/61607 AC sources’ functions through a large graphic LCD display front panel with an easy to use keypad. The GPIB, RS-232, USB, and Ethernet interfaces are available to control the AC source remotely.
Chroma AC Power Source 61500/61600 series have built-in 16-bit measurement circuits and firmware utilities to measure the true RMS voltage, current, true power, apparent power, reactive power, power factor, current crest factor, repetitive peak current, and inrush current. Using advanced DSP technology, the 61500 series can measure THD and up to 50 orders of current harmonics. The 5.7″ Color LCD provide users with easy to operate interface by integrating parameters and functions on a single display page. The panel is also capable of voltage and current measurement waveform display.
POWER LINE DISTURBANCEI SIMULATION (61500 SERIES)
In addition to the ability to program steady output voltage and frequency, The Chroma 61500 series provides powerful functions to simulate all kinds of power line disturbance conditions. The STEP and PULSE modes offer easy and convenient methods to execute single step or continuous output changes. The changes may be triggered by an internal or external event. This allows for an easy simulation of power line disturbances such as cycle dropout, transient spike, brown out, etc. The LIST mode extends this function for more complex waveform generator needs of up to 100 sequences with different start-end conditions that can perform almost any waveform by AC and DC components. The Chroma AC power source 61500 series is also capable of simulating all sorts of voltage dips, interruptions, and variation waveforms for IEC 61000-4-11 pre-compliance tests and IEC61000-4-14/IEC61000-4-28 compliance tests.
The 61509/61508/61507 models are capable of simulating the voltage dips, short interruptions and voltage variations test conditions for the IEC 61000-4-29* Electromagnetic compatibility (EMC) – Part 4-29: Testing and measurement techniques – Voltage dips, short interruptions and voltage variations on d.c. input power port immunity tests with test levels (%UT)) listed in the table below.
SLEW RATE SETTING FOR VOLTAGE AND FREQUENCY
Both 61500 and 61600 models allow users to set the slew rate of voltage and frequency. The program will follow the slew rate used to reach the final setting when the output voltage or frequency is changed. This function helps users verify the operating range of input power. For example, users can sweep voltage gradually from 90V to 264V instead of only measuring in steps such as 90V, 115V, 230V, and 264V. Additionally, in order to reduce the inrush current during motor startup or UUT power-up, users can decrease the slew rate setting to minimize peak current demands.
DISTORTION WAVEFORM, HARMONICS, AND INTERHARMONICS (61500 SERIES)
Traditional types of AC sources only provide output voltages with SIN waveforms; these types of AC sources are unable to meet or keep up with the latest test requirements needed for simulating the input voltage’s abnormal conditions with distorted waveforms. The WAVEFORM function allows users to set square, clipped-sine waves and 30 stored distortion waveforms. Besides that, IEC 61000-4-13 standard requires interharmonics simulations as well as harmonic waveforms.
The Chroma 61500 series allows user to compose up to 50 orders of harmonics based on 50Hz or 60Hz; the output will be a periodic harmonics distortion waveform. It also provides sweeping inter-harmonics functions. This means the fundamental frequency will be incorporated with a frequency sweeping component between harmonic frequencies. It can help find the resonance or the weakest points of the UUTs. The Chroma 61500 series uses advanced DSP technology to synthesize the harmonic and inter-harmonics waveforms. Therefore, it is capable of generating periodic harmonic and non-periodic harmonic distorted waveforms to perform IEC 61000-4-13 compliance tests.
SINGLE PHASE AND THREE PHASE OUTPUT
Model 61509/61508/61507/61609/61608/61607 AC sources are capable of delivering single or three-phase output depending on the application. Users can select these output modes easily through the front panel or by remote control. All models are able to provide full power output without derating even in single phase output configuration.
AC SOURCE PARALLEL OUTPUT FUNCTION
The 61509/61508/61507/61609/61608/61607 AC source models provide (Master-Slave) parallel output functions, which enable users to extend the AC source power output ability by connecting AC sources of the same series up to 2 units in parallel configuration. For example: connection two 61509 6kVA units will achieve total output power of 12kVA or connecting one 61609 6kVA with one 61607 3kVA unit will achieve total output power of 9kVA.
Chroma’s Softpanel is a graphical user interface that provides extraordinary capabilities and convenience by delivering control of the unit remotely.
