Response Time: ≤1 μs.
Galvanic Isolation: 3.0 KV at 50Hz, AC, 1min.

Applications: Suitable for AC variable speed drives, static converters for DC motor drives, power supplies for welding applications, battery-supplied applications, UPS, and SMPS.

Standards: Complies with UL94-V0, EN60947-1:2004, IEC60950-1:2001, EN50178:1998, SJ 20790-2000.

General Data:

Operating Temperature: -40 to +85 ºC.
Storage Temperature: -40 to +125 ºC.
Mass: Approximately 25g.

Mechanical Dimensions: All dimensions are in mm with a general tolerance of ±1mm.

Directions for Use:

Ensure current flows according to the arrowhead direction for correct phase output.
Primary conductor temperature should not exceed 120ºC.
Optimal dynamic performance when the primary hole is fully filled with the bus bar.
Primary turns should be at the top of the sensor for best magnetic coupling.
Voltage is measured at the output end when current passes through the sensor.
Custom designs available for different rated input and output currents.

Characteristics Chart: Includes pulse current signal response characteristics and effects of impulse noise.
