Applications
The HXS 50-NP is used in three-phase motor drive inverters, solar inverters, and battery management systems where non-contact current measurement up to ±150A eliminates series shunt losses. Its ratiometric output is directly compatible with microcontroller ADCs at 5V, enabling digital control loops for variable frequency drives and UPS systems. The sensor also serves in industrial energy monitoring equipment requiring accurate current measurement with galvanic isolation between high-power and signal circuits.

Frequently Asked Questions
How does the HXS 50-NP achieve galvanic isolation between the high-current bus and the signal output?
The HXS 50-NP uses a Hall-effect sensing element positioned within a magnetic core that surrounds the primary current conductor. The Hall cell detects the magnetic field generated by primary currents up to ±150A without any electrical connection to the high-power circuit, providing galvanic isolation typically rated at 2.5kV or higher between the primary and secondary sides. This allows direct connection of the 5V signal output to low-voltage microcontroller ADC inputs.
For a 3-phase 15kW motor drive at 400V, what output voltage does HXS 50-NP produce at 50A nominal?
The HXS 50-NP provides a ratiometric voltage output centered at Vcc/2 (2.5V at 5V supply) with zero primary current. At 50A nominal current, the output voltage is offset from this midpoint by a gain factor typically around 40mV/A, yielding approximately 4.5V at +50A and 0.5V at -50A. Designers must verify the exact sensitivity from the product datasheet for accurate ADC scaling in 15kW inverter control loops.
Can HXS 50-NP detect overcurrent events fast enough for IGBT protection in a motor drive?
Yes — the HXS 50-NP has a response time under 4µs, which is sufficiently fast to detect fault-level currents and trigger IGBT gate drive shutdown before the device's short-circuit withstand time (typically 10µs for modern IGBTs) is exceeded. This makes the sensor suitable for overcurrent protection loops in motor drives rated up to several hundred amperes when peak currents stay within the ±150A measurement range.
How does the HXS 50-NP compare to shunt-based current sensing for EV battery management systems?
Compared to a shunt resistor, the HXS 50-NP adds no series resistance to the high-current path, eliminating I²R losses that can reach several watts at 50A through a typical 1mΩ to 2mΩ shunt. It also provides galvanic isolation, protecting the BMS microcontroller from high-voltage faults on the battery bus. The trade-off is lower DC accuracy (typical offset drift of a few hundred mA) compared to precision shunts, so shunts remain preferred for high-accuracy state-of-charge estimation below 1A.
