Figure 17. Connection diagram of TMR7506
- Mounting method: 3 × Φ 4.5 mm holes (pick one)
- Primary through-hole dimensions: 20 mm × 15 mm
- Secondary terminal: Molex 22041041
- VOUT is positive when the primary current is in the same direction as the arrow indication on the label and
- Improper connection can cause 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.
