Introduction:
split core current transformers are a series of miniaturized openable products designed based on the improvement of current instrument and equipment software processing capabilities. Due to the increase in current monitoring equipment, there is a need for an open-type current transformer that is easy to install and compact. This type of product generally uses a small current signal output or a voltage signal output to maximize product accuracy and reduce hardware costs.
Normal use and installation conditions:
Installation location: indoors
Ambient temperature: -20℃~+75℃
Environmental humidity: It is recommended that the relative humidity should not be greater than 80%
Altitude: no more than 3000m
Atmospheric conditions: There is no serious pollution, corrosive or explosive media in the atmosphere
An environment without significant frequent vibrations and shocks
Storage temperature: -30℃~+85℃
