SFP200 Current Sensor
Current & Voltage Sensing
The SFP200MOD precisely measures currents from mA to kA, while also providing integrated voltage measurements. 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 +105 °C/+125 °C without connectors.
