A power supply to complete a variety of test solutions
Wide range output
There are two power supply products to be tested. The first power supply to be tested has a size of 50V/2A. The second power supply to be measured has a size of 25V/4A. This may require two 100W power supplies of different specifications or a single cost. The higher 50V/4A/200W power supply is tested. Although the cost is high, it is still not easy for engineers to randomly adjust the test state, and it is not conducive to the flexible configuration of laboratory instruments.
The test plan provided by ITECH is to solve this problem by using a wide range of design of IT6900A series DC power supply. Among them, the power is 100W, and the specification is 60V/5A. First, set the voltage of the IT6900A power supply to 50V. In this case, the current will be automatically set to 2A to complete the test of the first power supply to be tested. Then, set the voltage of the IT6900A power supply to 25V and the current is automatically set to 4A. The test of the second power supply to be tested can be completed. This scheme ensures the high reliability of test data while minimizing experimental time and equipment costs.
2. Intelligent programmable
In the testing of automotive electronics products, the test procedure is relatively complicated. For example, for a car horn test, engineers need a programmable power supply to test the characteristics of the horn. For example, the test process is as follows: 13V power supply for 10 minutes After that, the sound quality of the horn was tested, and the performance of the horn was tested after starting the test for 1S 13V on, 4S off and 1000 cycles. If you want to complete this test, the power supply of ITECH can provide the simplest and quickest method.
Customers can take advantage of the programmable features of the IT6900A series of wide-range DC power supplies from ITECH and provide powerful software to compose the best test solution. Before the experiment started, IT6900A series power supply was programmed according to experimental requirements. The programming method can also be selected according to the actual situation, such as programming on the power panel, or using the built-in standard RS232/USB/GPIB interface for remote Communication, programming operations on the computer. The power supply quickly receives the programmed instruction from the engineer. The test of the car horn can be automatically performed according to a predetermined procedure. The software will record the voltage and current data at this moment in time and display and record it on the computer's software monitoring interface. At the same time, since the IT6900A series DC power supply has a rich SCPI instruction, it can easily establish an intelligent switching test platform, which is particularly important for tests with secondary development requirements.
3. Ultra low ripple
For DC-DC switching power supplies and other equipment, engineers may worry that the ripple generated by the test equipment will be superimposed on the ripple of the device under test, resulting in large deviations between the test results and actual conditions.
In this case, it is also possible to use the IT6900A series DC power supply for testing. Because the voltage and current ripple coefficients of the power supply are ≤5mVp-p and ≤5mArms, respectively, engineers do not need to worry about the ripple ripple and affect the ripple characteristics of the device under test. 
The LED is a special electronic component, and the LED product as a constant current source has a high sensitivity to the current. Most of the power supplies will have a surge current generated at the moment of starting, which may damage the DUT, especially for current-sensitive products such as LEDs. It is not suitable for the testing of such products.
Idix IT6900A series DC power supply has the function of suppressing inrush current at the instant of start-up, so it can be perfectly applied to the reliability test of LED-related products.
The IT6900A series DC power supply can effectively suppress surge currents. The following figure can specify: 
On the left side of the figure is the selected general power supply test LED products, the current waveform obtained by the oscilloscope, there is a clear surge current; the right side is the current waveform measured by the IT6900A series DC power supply of the LED product, the current is smooth, No surge current is generated at the instant of start-up, so it is used for the reliability test of LED products and can protect the test product with extremely high current sensitivity.
In the aspect of burn-in testing, the OCP protection function of the IT6900A series DC power supply can protect the LED product under test during the long-term aging process, so as to prevent the inevitable abnormal current from being burned out during aging. Once the current is abnormally large, the power supply will enter the OCP protection state and stop the output.
5. The same power volume is small
With the continuous development and upgrading of electronic products, the equipment and instruments used in laboratory tests are also increasing. Many engineers are increasingly demanding the size of test instruments because they use too many devices in the test.
All of ITECH's power supply and electronic load products are of standard size, convenient for desktop use and on-shelf installation, and can meet the needs of engineers to the greatest extent in size and volume. Taking the IT6900A series DC power supply of IDEX as an example, it has an ultra-small size in the same product with the same power in the market. Such as the IT6952A, IT6953A these two models, only 2U ultra-small size has 600W of power, making the test application more flexible. 
The above cases are several application examples of the IT6900A series DC power supply of ITECH. In other industry related tests, there are more test solutions for this power supply. IT6900A series DC power supply, in addition to a single power supply to complete a variety of tests, it also retains a lot of hardware and functional design advantages, such as the function keys in the light is easy to operate in the dark environment, the standard size can be easily installed on the cabinet. The design concept of the ITECH IT6900A series power supply is to allow engineers in various industries to carry out the most perfect test program no matter what kind of tests they perform.
Traditionally, the power source is the product of voltage and current. According to market research, it was found that engineers often need to replace and use different specifications of power to test a variety of products. The entire process is very cumbersome, and the cost of equipment is also high. How to use a power supply in the laboratory to complete the testing of a variety of product specifications and to make the control method more flexible and diversified is a matter of great concern for the majority of R&D and design verification personnel. ITECH's IT6900A series DC power supply is designed for the insufficiency of traditional power supplies. A single power supply can replace several different types of traditional power supplies, covering the test requirements of different specifications of different industries, and can provide Linear power supplies are comparable to high precision. 4.
