The global AC power testing requirements demand more sophisticated AC Power Source that is capable of simulating a wide variety of AC line conditions, harmonic waveforms, accurate power measurements and analysis. Chroma 6500 Series Programmable AC Power Source delivers the right solution to simulate all kinds of normal/abnormal input conditions and measure the critical characteristics of the products under test. It can be utilized in R&D design, production test, and QA verification for commercial, industrial, and aerospace electronic products.
The input AC to DC stage in the AC Source incorporates modern power factor correction circuit to increase the input power factor more than 0.98
to meet the IEC regulations. It reduces the input current requirement and raises the efficiency up to over 80%. Using the isolation provided by DC to DC stage, the final DC to AC output stage eliminates the heavy low frequency output transformer, and decreases the weight to 30 Kgs only. The model 6530, packaged in 8 3/4 inches height rack-mountable unit, delivers full 3,000 VA output at 110V or 220V (while many competitors specify 3KVAoutput at 140V or 280V only).
Chroma 6500 Series AC Power Source has built in powerful Direct Digital Synthesis (DDS) waveform generator to provide low distortion (0.5%) sine or square waveform over a maximum frequency range from 15 to 2000Hz, with 0.01Hz (15 - 99.99Hz) resolution and 0.15% accuracy. For example, a unique clipped sine wave with 0% to 43% distortion and 0 to 100% amplitude can be generated by pressing the front panel keys for testing products under ac line distortion conditions.
Up to 30 different distortion waveforms including line conditioner, line filter, triangle wave, pulse wave, and peak spike, etc. are stored in the waveform library for execution. Users can preview the selected waveform on the LCD graphic display by pressing the "WAVE" soft key. To specify the waveform amplitude desired at each specific phase angle can modify the stored waveforms.
Testing for compliance to ac line harmonic immunity standards can be easily achieved. Sine wave with harmonic content specified by IEC 61000 standards can be recalled, downloaded into memory, and generated as needed.
Additionally, Chroma 6500 Series AC Power Source offers six user-defined arbitrary waveform buffers. Users can create the desired waveforms from a host PC and download them to the instrument through IEEE488 or RS-232C interface.
In addition to programming the steady output voltage and frequency, the AC Source provides a powerful tool to simulate all kinds of power line disturbance conditions. The step and pulse modes offer an easy and convenient method to execute single step or continue output changes. The output voltage amplitude, frequency, phase angle, and waveform shape can be controlled in response to input trigger generated from an internal or external event. With this capability, it is easy to simulate power line disturbances such as cycle dropout, transient spike, brown out, and ramp up, etc. This feature is very important for the maximum inrush current test when the UUT is switched on at 90 degrees, so is for the UUT's ridethrough effect check when an AC input transient spike is applied.
The List transient mode extends this capability further for more complex waveform generation needs. Up to 40 sequences of output setting can be precisely executed in response to a triggered or paced dwell time programmed in advance without computer intervention. Output triggers can be generated at the beginning and the end of each List loop setup to synchronize external events and to simulate power line disturbances for precompliance test of IEC 61000-4-11 Voltage Dip & Variation.
This instrument has 16-bit precision measurement circuit built-in and firmware utilities to measure the steady and transient responses of true RMS voltage, true RMS current, true power, power factor, frequency, peak repetitive current, inrush current, current crest factor, VA (apparent power), and VAR (reactive power). Using the high-speed sampling circuit, it can display the measured voltage and current as a waveform on the LCD display for transient state analysis without the need of a scope.
Chroma 6500 Series AC Source is easy to operate using the front panel keypad, or a remote controller. The printer interface is also available for printing out the instrument conditions or measurement readings. In ATE applications, model 6530 is controlled via IEEE 488, RS-232C, or Analog Programming Interface.
The instrument is designed with user friendliness in mind. It uses thermo-control DC Fan and the speed increases only when internal temperature rises and calls for more heat ventilation. This minimizes the acoustic noise from the fan during operation. The large size 320 x 240 LCD shows the test setup and operating status with the most comfortable visual effect possible. The software improves user interface by creating soft-keys to guide users during test execution. The rotary knob input enables users to adjust the voltage, frequency, and parameter setting on the fingertip with maximum speed and control.
The instrument has built in self-diagnosis routine to calibrate its performance and assist trouble shooting for failure. It is protected against over voltage, overload, over current, overpower, over temperature to ensure the instrument quality and performance for all kinds of applications in R&D, QA, Production, and field services.
Users can install the software in computer to control the AC source via IEEE488 and RS-232. The easy-use graphic interface help users to program or edit wareforms. All test program can be saved in a file for future recall.
More and more electronics manufactures have expanded their business to acquire worldwide product distribution. When a problem is identified, sometimes it is necessary to check if the products are susceptible to ac line disturbances. However, precious time would be wasted on gathering and transferring test equipment, man power and other resources to do a simple onsite test. The purpose of this application is to provide a solution using Chroma Power Analyzer 6630 to measure the voltage harmonics of the ac main on site. All recorded data can be sent to the lab. According to the data, users can use waveform editor function of AC Source 6500's softpanel to re-build the original distorted waveform. It can help engineers quickly point out the problem and come up with a solution.
Up to 30 different Distortion Waveforms and 6 user-Define Wareforms are stored in the Waveform Library for user edit and execution. Please refer to the user's manual for more factory-installed Waveforms and specifications.
