Applications

Variable speed drives

Welding machine

Battery supplied applications

Uninterruptible Power Supplies (UPS)

Electrochemical

Mechanical dimension (for reference only)

current sensor drawing

Remarks：

1. All dimensions are in mm.

2. General tolerance ±1mm

Directions for use

1. Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.

2. The primary conductor should be≤120℃.

3. The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

4. The primary turns should be at the top of the sensor for the best magnetic coupling.
