Frequently Asked Questions (FAQs)

What current ranges are available in the ISB-A 800 Series?

+
Models support ±100 A to ±670 A, allowing designers to choose the ideal range for light, medium, or heavy-load power systems.

What type of output does the sensor provide?

+
A proportional analog voltage output (e.g., 20 mV/A or 6.67 mV/A depending on the model) that interfaces easily with ADCs and control processors.

Can the ISB-A 800 measure both AC and DC currents?

+
Yes — the DC–200 kHz bandwidth allows sensing of DC, AC, and switching waveforms used in converters and motor drives.

How does the 4300 VAC isolation rating impact system design?

+
It provides a safe electrical barrier between high-voltage supplies and control electronics, ensuring compliance with industrial insulation requirements.

Is the response time suitable for fast protection circuits?

+
With ~3 µs response time, the ISB-A 800 supports real-time overcurrent protection and dynamic control loops.

Can this sensor be used directly on a busbar?

+
Yes — the mechanical design is optimized for busbar mounting, providing stable alignment and reducing wiring inductance.

What installation guidelines should be followed?

+
Use non-magnetic screws to prevent flux distortion and ensure maximum measurement accuracy.

Does the analog output depend on supply voltage?

+
Yes, the output is ratiometric with VDD, so proper supply regulation ensures consistent measurement accuracy.

What applications benefit most from the wide bandwidth?

+
Solar inverters, motor drives, welding systems, and fast-switching DC/DC converters all rely on wideband current feedback.

How should a designer choose the right current range?

+
Select a model that provides enough headroom for peak currents while maximizing output resolution for the expected operating range.
