Alternator Alpha Compact 14/140 VP cu Alpha Pro III

This kit includes the Alpha Compact 14/140 VP alternator, the Alpha Pro III smart charge regulator, a standard pulley for 8-rib multiprofile belt (48.1 mm diameter), a hydrocarbon-resistant wiring harness, and a battery temperature sensor.

This model is specifically designed to fit Volvo Penta marine engines. It uses a swivel arm mounting system adapted to these engines.

The Alpha Compact 14/140 VP alternator requires a power take-off (PTO - Power Take-Off) of approximately 4.8 kW from your engine to operate at its rated capacity.

Yes, absolutely. With the included Alpha Pro III regulator, the alternator is fully compatible with lithium-ion batteries, as well as lead-acid, gel, and AGM batteries.

No, this model is not isolated by default. However, if your installation requires strict galvanic isolation (to prevent electrolysis, for example), an insulating bushing kit is available as an option.

The Alpha Pro III regulator turns the alternator into a three-stage smart charger (Bulk, Absorption, Float). It automatically compensates the charging voltage based on temperature to effectively protect your battery bank.

The alternator benefits from optimized cooling thanks to an integrated dual-fan system. This allows it to maintain high performance and operate safely up to a temperature of 120 °C.

The Alpha Compact 14/140 VP delivers a nominal current of 140 A and is designed to charge battery banks operating under a 12 V system voltage.

Yes. The included Alpha Pro III regulator is fully compatible with the MasterBus network via its two RJ-45 ports. This allows complete system monitoring (temperature, current, alarms) from a compatible display.

The Alpha Compact 14/140 VP alternator weighs 6.7 kg, making it a relatively lightweight and compact unit for its power output.

The alternator is supplied ready for use with a standard pulley for 8-rib multi-groove belt, with a diameter of 48.1 mm.

The intended rotation direction for this alternator is clockwise (the direction of the clock hands), when viewed from the pulley side.

The sensor (included) measures the battery temperature and transmits the data to the charge controller. The controller automatically adjusts the charging voltage (-30 mV/°C at 12 V) to prevent overcharging and extend battery life.

No, the 14/140 VP model is designed exclusively for 12 V systems. For a 24 V system, you need to look at the 28/xx series models (such as the 28/110 or 28/150).

For a cable length up to 3 meters, a 50 mm² cross-section is recommended. For a length between 3 and 5 meters, a 70 mm² cable is advised to minimize voltage drop.

The regulator manages numerous safety alarms, including: excessive temperature of the alternator or battery, battery voltage too high or too low, and abnormal excitation current (too high or too low).

Power connection for the positive pole is securely made via two M8 studs (2x M8) located at the rear of the alternator.

The alternator starts reducing its charging current (charge reduction) when its internal temperature reaches 100 °C. If it reaches 120 °C, it stops charging completely to protect itself.

Yes, via the MasterBus network, the Alpha Pro III can retrieve the precise temperature and voltage data measured directly by the MasterShunt, further optimizing the charging cycle.

Reduced slip minimizes battery load. You must check belt tension. If the issue persists, you can enable the "Power Curve" option in the MasterBus settings of the regulator to reduce initial load and minimize mechanical torque demanded from the engine.
