Introductions of product
WYJ series DC voltage regulatIion source is the universal apparatus which assembled by intergrated components,DC current voltage grating continous adjustment,reliable stablization,current-limiting protecting,simple structure,convenient maintain,source steady and fine ripple coefficient,low-noise ,small volume,it is divided into single route,double route and multi route output separately.

usage situations
Widely used in post and telecommunication, reseach institutions, institutions of high education, industrial manufacture and automatical equitments.

precautions
red end is positive electrode,black end is negative electrode and GND is grounding
set the volatge selection switch in the smallest scope usage voltage,if the usage voltage is 9V,the selection switch should be in 10V,set the voltage to the rated voltage,if need the precise value,please use the precision measurement instrument calibration.
The same two specification instrument series connection,the output voltage is the sum of double output voltage,it also can be used in parallel.
good quality and best price, custom-made is also accepted
