Shunt Current Sensor "VSM0001"

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.

Analog 50A current sensor (AC / DC)

It is possible to monitor the current of the project every second for energy saving and circuit protection.

This product is a breakout board for the fully integrated Hall effect-based linear ACS758 current sensor. It provides accurate current measurements for both AC and DC signals, and the thickness of the copper conductors allows the device to survive in high overcurrent conditions. The ACS758 outputs an analog voltage signal that varies linearly with the detected current. 【Features】 ■ Arduino interface compatible ■ Standard bandwidth of 120 kHz ■ 3μs output rise time in response to step input current ■ Output voltage proportional to AC or DC current ■ Factory calibrated for accuracy, etc. *For more details, please refer to the external link or feel free to contact us.
