Mechanical dimension (for reference only)
Remarks:
1. All dimensions are in mm.
2. Secondary pin size and tolerance: width:0.5±0.1mm;thickness:0.25±0.05mm
3. General tolerance ±1mm
Directions for use
1.When the current will be measured goes through a sensor, the voltage will be measured at the output end. (Note: The false wiring may result in the damage of the sensor)
2. Custom design in the different rated input current and the output voltage are available.
