Semiconductor regulator for the alternator 14V, typ MF-14V /4A1

The regulator is determinated as a part of a supply set 14 V. for a compact alternator to the effect 110A , with a environs temperature T=20°C. It contains this parametres: It is compactibile with the regulators made by - MOTOROLA, THOMSON and the final producers of the compact alternators BOSH , VALEO and DELCO REMY.

- the protection against the overload and the short circuit on the side of the load
- the current limitation
- the thermal protection
- the overvoltage protection
- max. current in calm state 20 mA
- the protection against the electrical discharges
- possible diagnostik by a current sensor, output for the CAN

For CAN BUS gives informationes about the alternators condition:
- It takes rotations of the alternator
- Chargering control
- Condition of the carbon
- Temperature controle of the alternator
- Condition of the stators winding - max. takes rezistance 5 Ohm
- Condition of the diode block - Zener diode
