Frequently Asked Questions (FAQs)

What should designers consider when selecting a model?

+
Match current range, output slope, bandwidth requirements, isolation needs, and wiring layout for the intended system.

How does the ISB-A 802 differ from the ISB-A 800?

+
The ISB-A-800 uses a 1.00 mm pitch shrouded header connector (JST BM04B-SRSS-TB with the appropriate mating connector), providing a creepage distance of 8.5 mm. In contrast, the ISB-A-802 is supplied with stranded #22 AWG UL3239-rated lead wires, rated for 3 kV. The standard 150 mm lead length significantly increases the creepage distance to 158.5 mm, with custom lead lengths available upon request.

What current ranges does the ISB-A 802 support?

+
Variants measure currents from ±100 A to ±670 A, making the series suitable for a wide range of industrial and power-conversion applications.

Can the sensor measure both AC and DC signals?

+
Yes — the DC–200 kHz bandwidth supports DC, low-frequency AC, switching waveforms, and high-speed transient detection.

Why is the 4300 VAC isolation important?

+
It ensures safe separation between high-voltage power paths and low-voltage control electronics, critical for converters, inverters, and battery packs.

What type of output does the sensor provide?

+
A ratiometric analog voltage proportional to sensed current. The slope depends on the variant (e.g., 20 mV/A or 6.67 mV/A).

Where is the ISB-A 802 especially useful?

+
In systems requiring remote placement of the sensor — such as inside power cabinets, harnesses, or areas with mechanical constraints.

Is the response time suitable for protection circuits?

+
Yes — the ~3 µs response allows fast overcurrent detection and stable control-loop feedback.

What are the power supply requirements?

+
The device operates from a regulated 5 V ±0.5 V supply for consistent analog output.

How should the sensor be mounted for best accuracy?

+
Secure placement with non-magnetic hardware is recommended to prevent magnetic distortion. We recommend mounting the sensors with non-magnetic screws for maximum accuracy - materials such as stainless steel, brass, bronze, copper or aluminum.
