RPM inputs
Charger alternator connections
This schematic diagram shows the basic way the charger alternator and the MEC 310 can
cooperate.
Only one running feedback is needed, but for optimal safety and function both the RPM (Tacho)
input and the digital running feedback (D+) can be used as in the example below.
Rex: Excitation resistor: 12V systems: 47Ω 3 W
24V systems: 100Ω 6 W
