Functional Description :
The Winson WCS1720 provides economical and precise solution for both
DC and AC current sensing in industrial, commercial and communications
systems. The unique package allows for easy implementation by the customer.
Typical applications include motor control, load detection and management,
over-current fault detection and any intelligent power management system
etc…
The WCS1720 consists of a precise, low-temperature drift linear hall
sensor IC with temperature compensation circuit and a current transformer
with 0.6 mtypical internal conductor resistance. This extremely low
resistance can effectively reduce power loss, operating temperature and
increase the reliability greatly. Applied current flowing through this conduction
path generates a magnetic field which is sensed by the integrated Hall IC and
converted into a proportional voltage.
The terminals of the conductive path are electrically isolated from the
sensor leads. This allow the WCS1720 current sensor to be used in
applications requiring electrical isolation without the use of opto-isolators or
other costly isolation techniques and make system more competitive in cost.
Winson reserves the right to make changes to improve reliability or manufacturability.
