Mastervolt 12/130 Incl. 3-Step Alpha Pro III Charge Regulator

Alpha 12/130 III

Delivery includes Alpha Pro III charge
regulator. 

Features:

• Fast and complete charging of starter and service
  batteries.
• Power supply for all consumers.
• 12 V and 24 V versions.
• 75 A to 150 A charge current.
• Standard delivered with Alpha Pro III charge regulator for an
  optimal performance and longer-lasting batteries.

Using a Battery Mate or battery isolator in conjunction with an
Alpha alternator makes it possible to easily charge two or three
separate battery sets simultaneously.

TIP: A second alternator on the main engine, combined with a
larger battery bank and inverter, could be an alternative for a
generator.

For all engine types

Alpha alternators are equipped with several fixations for
customised alternator brackets, available from your installer or
engine supplier. Some engine brands come with Mastervolt alternator
brackets as an option.

Fast charging, even at a stationary rpm

Standard alternators only supply the specified capacity at a
high rpm. The Mastervolt Alpha alternator is specifically designed
for powerful charging, even with a low engine rpm. 

Multigroove pulley

The 12/130 and 24/75 models are also available with a
multigroove pulley.

Performs above 40 degreesC

Forced cooling by fan operation of the pulley provides a lot of
power in higher temperatures, especially close to the engine.
