Functional Description :
The Winson WCS1700 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 WCS1700 consists of a precise, low-temperature drift linear hall
sensor IC with temperature compensation circuit and a diameter 3mm through
hole. Users can use system’s own electric wire by pass it through this hole to
measure passing current. This design allow system designers to monitor
any current path without breaking or changing original system layout at all.
Any current flowing through this hole will generate 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 WCS1700 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.
