Alternatorius Alpha Compact 28/110 su Alpha Pro III

The alternator is supplied as standard with the Alpha Pro III external charge regulator, a battery temperature sensor, and the necessary wiring (1.5 m oil-resistant harness) to connect the alternator to the regulator.

It delivers a nominal current of 110 A at 24 V at 6000 RPM, which corresponds to a generated power of 6.2 kW. It also offers excellent low-RPM charging capability by providing 41 A as early as 1800 RPM.

Yes, absolutely. Thanks to the included Alpha Pro III smart regulator, this alternator is fully compatible with lithium-ion battery banks, as well as with open lead-acid, Gel, and AGM batteries.

This alternator is designed for mechanical integration via a cardan arm (floor-mounted setup). It is important to calculate the pulley ratio correctly during installation to optimize its performance curve.

Unlike classic models requiring wide clearance, the Alpha Compact series features an internal dual-fan system with a patented magnetic design. This allows it to maintain optimal performance in confined environments.

Although it is equipped with efficient internal cooling, it is still recommended to ensure good air circulation in the engine compartment. If the alternator temperature exceeds 85 °C, the regulator will automatically start reducing the charging current to protect it.

The Alpha Compact 28/110 alternator has a very low cut-in speed: it starts producing current at just 1400 rpm (rotational speed of the alternator shaft).

Yes, the Alpha Pro III regulator is equipped with two RJ-45 data ports. This allows it to be easily integrated into a MasterBus network for monitoring, configuring, and optimizing your energy system from a compatible display.

This alternator weighs just 7.4 kg. It thus offers an excellent power-to-size ratio compared to factory-fitted alternators, which are often heavier and less efficient.

The positive output connections are made via two M8 threaded terminals. It is critical to use cables with an appropriate cross-section to safely handle the 110 A current and minimize voltage drops.

No, this alternator model is not galvanically isolated as standard. If galvanic isolation is strictly required for your marine installation, you will need to use a specific insulating bushing kit (available as an option).

The Alpha Compact 28/110 alternator is designed to rotate clockwise.

The included battery temperature sensor allows the controller to dynamically adjust the charging voltage (-60mV/°C for a 24 V system). This protects the cells (especially for lead-acid batteries) from overheating and extends their lifespan.

Yes, the alternator has a dedicated connection for the W (RPM) signal via an insulated quick-release terminal, allowing easy connection to a standard tachometer.

The regulator turns the alternator into a smart charger managing three automatic phases:

Bulk: main charge at maximum current. Absorption: voltage hold to complete the charge to 100%. Float: maintenance charge to preserve the batteries.

The Alpha Compact 28/110 alternator is extremely robust and can support rotational speeds up to 15,000 RPM, providing great flexibility for engine pulley ratio selection and calculation.

The alternator is designed to operate up to a maximum temperature of 120 °C. Above 85 °C, the regulator progressively reduces the charge. If the temperature reaches 120 °C, the charge stops completely to prevent any material damage.

The battery type (Lead-Acid, Gel, AGM or Lithium) is configured easily via the MasterAdjust software interface, accessible when the charge controller is connected to a MasterBus network.

Yes, the regulator uses LED indicators and flashing sequences (e.g., on the D+ connection) to signal alarms such as excessive field current or abnormal voltage. These alerts are also relayed over the MasterBus network.

No, the Alpha Compact 28/110 is an alternator designed exclusively for systems operating on 24 V DC. It cannot be used to charge a 12 V battery bank.
