How Programmable Linear DC Power Supplies Improve Test Efficiency
A linear power supply first reduces the voltage amplitude of AC power through a transformer, then rectifies it through a rectifier circuit to obtain pulsed DC power, and finally filters it to obtain a DC voltage with small ripple voltage. The advantages of linear power supply are high stability, high precision, and small ripple, making it an essential testing tool in some fields.
The IT6100 series programmable linear power supply is one of the many star products of Adidas. 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, ohmmeter and other functions, making this power supply perform better in testing.
The LIST function allows the power supply to automatically output according to the sequence edited by the tester. It can edit the value and time of each step in the sequence operation to generate various output changes. This function can improve the efficiency and accuracy of testing in some complex tests. For example, in the testing of a car horn, engineers need a programmable power supply to test the characteristics of the horn. The testing process is as follows: after supplying 14V continuously for 10 minutes, the sound quality and other performance of the horn are tested, and the performance of the horn is tested after 1 second of 14V on, 4 seconds off, and 1000 cycles. If there is no power supply with LIST function, it is necessary to connect the power supply to the computer and program it to execute according to the program, which increases the complexity of testing and reduces testing efficiency.
If the IT6100 series power supply is used, it only needs to be programmed according to the experimental requirements before the experiment begins. The programming method can also be varied according to the actual situation, such as programming on the power supply panel, remote communication using communication interfaces, programming operations on the computer, etc. The power supply quickly receives the program instructions written by the engineer, and the testing of the car horn can be automatically carried out according to the predetermined program. The software will record the voltage and current data in real time and display and record it on the software monitoring interface of the computer. This greatly simplifies the difficulty of testing and improves the automation level of testing.
