Shunt current sensor capable of detecting currents up to ±400A with built-in isolation amplifier.
The VSM0001 is an insulated current sensor that integrates a high-current shunt from the HS series with a detection circuit. It is compact (L×W×T: 72mm×36mm×13mm) and lightweight (approximately 30g), contributing to the miniaturization and space-saving of existing sensors. It is suitable for high-precision current detection in automotive, industrial equipment, and energy sector battery management applications. 【Features】 ■ Measurement current range: ±400A (at fastening part below 75℃) ■ Detection accuracy: ±1% or less @ 25℃ ■ Low loss (detection part resistance value: 100μΩ) ■ Supports insulation between current path and output signal (using insulated amplifier) *For more details, please refer to the PDF document or feel free to contact us.
