Remarks: If it is required to further reduce the input and output ripple, the parameters of the LC filter can be increased appropriately, but it should be noted that the external capacitor at the output cannot be selected too large and should be lower than the maximum capacitive load of the product.
 
一. The main parameter detection method of DC-DC module power supply products
Adopt standard Kelvin four-terminal input and rated load test (as picture)
Test conditions: room temperature TA = 25 degrees Celsius, temperature: less than 75% of nominal input and rated load.
       
 
 
     二. Reference method for reducing noise common mode interference in the use of DC-DC module converter.
            The module power supply will generate common mode and differential mode noise at the switching frequency. The way to reduce the text wave and noise is to add a passive LC or RC (large loss) filter network at the input and output ends. The self-resonant frequency of L is much higher than the switching frequency of the module. The current value allowed to pass is preferably selected to be more than twice the maximum input current of the module. The internal resistance should be small to reduce DC loss.
 
 
三.DC-DC module converter isolation withstand voltage test method
 
 
 
Safety precautions and conventional methods of product high voltage isolation test:
1、As show above picture 1: Set the rated high voltage value according to the product isolation voltage specifications. Please pay attention to personal safety when testing and beware of electric shock!
Test condition: room temperature TA = 25 ℃, humidity <75%
2、The operator of the withstand voltage test must wear rubber insulation (insulation voltage> 10KV) gloves, and place insulation pads on the workbench and seat floor to prevent high voltage electric shock. 
3、The pressure tester instrument must be reliably grounded and cannot be detected in a high temperature, humid and dusty environment.
4、When the withstand voltage tester is connected to the test object, it cannot be operated with power on, and the output voltage value of the high voltage tester must be zero.
5、When the instrument is in the startup state or the high voltage is not released, it must not touch the measured object, test line or high voltage test line and test fixture.
6、The product test method like above picture 1: all pins of the input and output terminals are connected in parallel, and the test is performed for 1 minute according to the isolation voltage value given by the product。
7、According to the test standard for withstand voltage, the withstand voltage value is gradually adjusted upward from 0. When the withstand voltage value is adjusted to the set maximum withstand voltage and maintained at the highest withstand value for one minute.
8、The pressure test itself is a destructive test. The fewer times the product should be done, the better. If the customer needs multiple tests, the general requirements are: the first measurement is based on the voltage value of the specification, and the voltage value should be reduced accordingly for each subsequent test, otherwise the product performance will be reduced or directly damaged.
