The linear power supply firstly reduces the voltage amplitude of the alternating current through the transformer, and then rectifies by the rectifier circuit to obtain the pulsed direct current, and then filters to obtain the direct current voltage with a small ripple voltage. Linear power supplies have the advantages of high stability, high precision, and low ripple, which are indispensable test tools in some areas.
The IT6100 series programmable linear power supply is one of the many Star products of Aidex. It is designed with pure linear technology and has many advantages of linear power supply. It also has LIST programming function and built-in 5 1/2 digit digital voltmeter. Features such as ohmmeters make this power supply perform better in testing.
LIST function
The LIST function allows the power supply to be automatically output in the sequence edited by the tester. It can edit the value and time of each step in the sequential operation to produce various output changes. This function can improve the efficiency and accuracy of the test in some more complicated tests. degree. For example, in the test of a car horn, engineers need a programmable power supply to test the characteristics of the horn. For example, the test process is as follows: after 14V power supply for 10 minutes, the sound quality of the horn is tested, and the test 1S 14V on is started. 4S off, the performance of the horn is detected after 1000 cycles. If there is no LIST function power supply, you need to connect the power supply to the computer and program the power supply according to the program. This increases the complexity of the test and reduces the test efficiency.
If you use the IT6100 series power supply, you only need to program the power supply according to the experimental requirements before the experiment starts. The programming method can also be variously selected according to the actual situation, such as programming on the power supply panel or using the communication interface for remote communication. The programming operation on the computer, the power supply quickly receives the program instructions programmed by the engineer, the test of the car horn can be automatically performed according to the predetermined program, and the software will record the voltage and current data at this moment in real time and display It is recorded on the software monitoring interface of the computer, which greatly simplifies the test and improves the automation of the test.
Low ripple
First, let's first explain the concept of power supply ripple: the AC stray component of the DC power output is called ripple and noise, or called Periodic and Random Devia TIons. These terms are often used interchangeably. Ripple refers to the AC cycle signal in the output. The ripple appears as a spurious response when viewed in the frequency domain.
For DC-DC switching power supplies and other equipment, engineers will worry that the ripple generated by the test instrument will be superimposed on the ripple of the device under test, and the test results will be greatly deviated from the actual situation.
In this case, the IT6100 series DC power supply can also be used for testing. Because the power supply is a pure linear power supply design, the voltage and current ripple coefficients are at least ≤3mVrms and ≤3mArms, so engineers do not have to worry about ripple superposition to affect the ripple characteristics of the device under test.
Built-in 5 1/2 digit voltmeter, ohmmeter
In the test process, in addition to the power supply, voltmeters, ohmmeters and other instruments are required. The IT6100 series power supply has a built-in 5 1/2 digit digital voltmeter and ohmmeter. The measurement accuracy is 0.1mV/0.1mA. Output voltage and resistance values ​​can be easily and accurately measured with any complex settings.
in conclusion
Idex has been committed to the research of related fields in the field of "power electronics" products for many years. IT6100 series programmable linear DC power supply continues the high performance and high quality of the company's products, ensuring accurate testing and improvement. The efficiency of testing is widely used in multi-domain testing.
