10.2 Closed Loop Current Sensor
The MGL Avionics magnetic closed loop current sensor provides a 0.5V to 4.5Vdc output voltage which is proportional to
a 50A bi-directional input current.
Advantages of closed loop current sensors over conventional current measurements techniques is that they provide the
highest accuracy, are ideal for noisy electrical environments and they provide complete electrical isolation f rom the
current carrying conductor.
Please see the MGL Avionics Closed Loop Current Sensor manual for connection information

8-30Vdc power via power switch / circuit
breaker and fuse.
2
Black
Ground. Connect the ground to the engine
block, and the engine block to the battery
negative. Do not connect the INFO-1 ground
directly to the battery negative. This must be
routed via the engine block.
