Brand: DF Robot
Category: Current and Voltage Sensor
Tags: DF robot Sensor, DFRobot Gravity, 50A (AC/DC) V2 Current Sensor

This fully integrated Hall Effect-based linear SC780 current sensor gives precise measurement for both AC and DC currents up to 50A. The thickness of the copper conductor allows the survival of the device at high over-current conditions.

The SC780 can output an analog voltage signal that varies linearly with sensed current.

The input and output are designed as through-hole vias and slots, which allow for soldering thick electrical wires and T-shaped connectors. The polarity of the input power is clearly labeled on the board so users can conveniently solder wires or use metal alligator clips to make the electrical connections.

The current sensor features enhanced heat dissipation and circuit-protection functions, which typically can be applied to scenarios such as motor control, load detection & management, aeromodelling, and robot over-current detection.
