Application: Incorporated into applications where it is necessary that the current sensor must be capable of responding to a wide operating current range, a wide frequency bandwidth and/ or is exposed to harsh operating conditions. Suitable for measuring AC current and DC current pulses. Features:

• Split core design permits installation while the primary conductor is “live”.
• Single loop primary, capable of accommodating a range of primary conductor sizes.
• Characterized by high sensitivity, accuracy, linearity, minimum phase shift.
• Suitable for harsh operating environments (temperature, humidity, EMI).
