US CR MAGNETICS INC detachable DC current sensor
The CR5210S DC current sensing sensor design provides a DC signal proportional to the DC sensed current. It is mainly for daily DC power applications; 2-10 amperes utilize advanced magnetic modulator technology, while 20 amperes and above utilize Hall effect technology. The CR5210S has +/-5 V DC, is bidirectional, and is ideal for battery charging applications.
