- Mounting method: 1 × Φ 4.5 mm hole and 1 × Φ 4.5 mm slotted hole
- Primary through hole dimensions: 40 mm × 30 mm
- Secondary electrical connection: Molex 353120460
- VOUT is positive when the primary current (I P) is in the same direction as the arrow indication on the label
- Improper connection may result in permanent damage of the sensor.
- Excessive capacitive load may result in distortion of output signals when measuring high frequency primary
signal. Please refer to Output Voltage vs Load Capacitance Curve.
- Dynamic performances (di/dt and response time) are best with a single busbar completely filling the primary
- Sensor is customizable upon request.
