SFP203 Current Sensor
Current & Voltage Sensing
The SFP203MOD precisely measures currents from mA to kA. Designed specifically for the needs of electric vehicles (EVs) and Energy Storage Systems (ESS), this cost-effective member of Sensata | Sendyne's SFP family communicates via an isolated CAN 2.0B interface (500 kbit/s). The module achieves a total accuracy of ±1.0% for current and voltage measurement over the whole operating temperature range of –40 °C to +125 °C.
