Note1: Due to space limitations, above is only a part of our product list, please contact with our sales team for more items.  

Note 2:The maximum capacitive load means the max. electronic capacitive load could be connected to +Vo or –Vo, If exceed it, the product cannot start up normally. 

Test Condition: Unless otherwise specified, data in the datasheet should be tested under the conditions of inputting nominal voltage, pure resistance rated load and Ta=25

Test Application Reference 

1.Recommended test circuit 

                                 

2. Ripple & Noise Test:(twisted pair method, 20MHZ bandwidth)

Test Method:

(1)12# twisted pair to connect, Oscilloscope bandwidth set as 20MHz, 100M bandwidth probe, terminated with 0.1uF polypropylene capacitor and 47uF high frequency low resistance electrolytic capacitor in parallel, oscilloscope set as Sample pattern.

(2) Input terminal connect to power supply, output terminal connect to electronic load through jig plate, Use 30cm¡Ó2 cm sampling line, Power line selected from corresponding diameter wire with insulation according to the flow of output current

3.Remote Control REM Application Circuit

REM could be suspended when do not use it, the voltage of REM is less than 0.5Vdc, output switches off.

4. Output TRIM Application Circuit

TRIM could be suspended when do not use it, the output maximum adjustment cannot exceed ¡Ó10% of output voltage +Vo.
