HOP Series – Split Core Current Sensors
The HOP Series consists of compact split‑core current sensors designed for precise electronic measurement of DC, AC, and pulsed small currents in industrial applications. Covering nominal current ranges from 200 to 2000 Arms, HOP sensors provide reliable galvanic isolation between the primary and secondary circuits, ensuring safe and accurate current monitoring.
Operating with a dual power supply from ±12 V to ±15 V, HOP current sensors deliver an instantaneous voltage output, enabling fast signal acquisition in dynamic systems. A key feature of the HOP Series is the availability of three different rectangular aperture sizes, offering flexibility for various conductor or busbar dimensions.
Leveraging split‑core technology, the HOP Series enables easy installation and retrofitting without disconnecting the primary circuit.
HOP – Features and benefits
Main characteristics
- Open‑loop Hall‑effect current transducer
- Measurement of isolated DC and AC currents from 200 A up to 2000 A nominal
- Suitable for busbar mounting or panel mounting
- Rectangular or hole shape aperture options, available in multiple sizes
- Compact mechanical design
- Insulating plastic case recognized according to UL 94‑V0
Benefits
- Low power consumption
- Easy installation, thanks to split‑core construction
- High insulation between primary and secondary circuits
- No insertion losses, as the conductor passes directly through the sensor
Typical applications
The HOP Series is designed for industrial current measurement in applications requiring flexibility in conductor geometry, such as:
- Telecom power supplies (monitoring and measurement)
