Current Sensor

Sencoch GZC series current sensors are based on open-loop Hall effect principles, integrating a high-precision, low-temperature-drift linear Hall IC with a low-insertion-resistance current conduction path (typical internal resistance as low as 0.21mΩ). They convert the magnetic field generated by AC or DC current into an analog voltage output proportional to the input current. The series offers excellent linearity (typical nonlinearity error of ±0.25% over the full temperature range), ultra-fast output response time (<1.8µs), and a high signal bandwidth of up to 240kHz, enabling accurate capture of rapidly changing current signals.

The series supports bidirectional rated current detection from ±10A to ±120A, operates from a single 5V power supply, and covers a wide temperature range from -40°C to 105°C. The primary current terminals (IP+ / IP-) are galvanically isolated from the signal terminals (VCC / VOUT / GND) with a high isolation withstand voltage of 4300Vac, and the products comply with UL, CE, and RoHS safety standards, ensuring reliable operation in noisy industrial and communication environments.

GZC series current sensors are widely used in medium- and low-power frequency converters, motor phase current sensing, string photovoltaic inverters, chargers and power converters, MPPT maximum power point tracking, DC power supplies, overcurrent protection, and uninterruptible power supplies (UPS). They deliver high-accuracy, low-power current monitoring and protection solutions for a variety of systems.
