Changzhou Yinquan Electronics Co., Ltd. was established in 2007, 

specializing in high-precision switching power supply for laboratory equipment. 

The starting point of the company is a very difficult product - deuterium lamp switching power supply. 

There is a certain gap between our domestic instruments and foreign instruments, 

then the accessories of our instruments and foreign instruments also have a big gap, 

many predecessors are developing deuterium lamp switching power supply, 

but there is always no mature products to use.

Yinquan Electronics spent 6 years,

with the help and funding of the older generation of instruments, 

to develop a low-cost and practical YQK002 deuterium lamp switching power supply. 

The deuterium lamp switching power supply of Yinquan electron is the first in China and fills the gap in this field.
