Company Profile
Jiaxing Wisdom Electronic Tech Co., Ltd.is a science and technology
manufacturer specialized in research, development, production and
sales of latching relay, shunt resistors and current transformer.
WSD passed ISO9001-2008, ISO14001: 2004 and OHSAS18001:2007.
Currently more than 50 kinds of Current transformer with over 100
specifications are under production, ranging from WSD-701 to WSD-753 and continuing being updated in our website. Primary
maximum current is from 5A to 200A. Some products are equipped with anti-dc component and anti 300-500mT magnetic
disturbance. Products precision reaches 0.05 grade.
The main products attain certificates of CQC, VDE, UL and ROHS,
etc. Furthermore, WSD attended Conference of Technical
specifications of components - Part eighth, used in electrical
energy meters of National Grid Corp standard. Also, it is one of
the drafters of “latching relay used in electrical energy meter” of
Standardization Technical Committee of National Electrical
Instrument.
Latching relays are widely used in all kinds of application areas
of smart meter, smart home, load control, synchronous switch,
electrical leakage protector, etc.
WSD has a long-term partnership with foreign customers from
Denmark, Japan, Korea, Spain, etc, and sets many independent
automated production lines. WSD actively participates in the
development of global smart grids of China, Denmark, Spain, etc.
and is recognized by international famous electricity meter
manufacturers and have a long-term collaboration.
