Alternator 100 Amp Dual Voltage 28/14 Volt For M1078 LMTV & M1083 MTV, (Niehoff N1511-1 / N1511-2) 12423625

Out of stock, to replace see N1509-1

Dual voltage alternator, simultaneous outputs of 28 Volt / 14 Volt, 100 Amps.
This alternator is used on the M1078 LMTV series and M1083 MTV series.

C.E. Niehoff Co. model N1511-1 / N1511-2. (Depending on stock we may ship the -1 or -2. They are fully interchangeable with no performance difference.) Military P/N 12423625. NSN 6115015040680 for N1511-1 / 6115015040680 for N1511-2. Also replaces P/N 12422863, 12423625-001, N1509-1, N1509-2, 12422863-001. Can replace model N1506-1 which had a more basic regulator without the diagnostic indicators. Consult service literature for details on model differences.

Alternator is brushless design (no brushes and no slip rings to wear out).

Integral N3207 dual voltage regulator with diagnostic LED indicators for each output.

Compatible with the N2003 Load & Battery Control.

Rated output of 100 amps is maximum combined total current between the two outputs.

Upper voltage output (28V) is rectified with standard diodes. Lower voltage output (14V) is controlled by SCRs in the drive end housing.

Alternator output current is self-limiting and will not exceed rated capacity of alternator.

Overvoltage shut down protection.

Regulator setpoint has negative temperature compensation. At 75ºF, the setting is 28.2 V for 28 V system and 14.1 V for 14 V system.

AC terminal (used on some vehicles) to sense alternator rotation or to provide a signal to the N2003.

One wire energize power (24 volt on E terminal) input to regulator. All input and output connections via terminal studs.
