Alternator Alpha Compact 14/200 með Alpha Pro III

The Alpha Compact 14/200 alternator delivers exceptional energy output even at low RPM (from 1350 rpm). It is ideal for quickly recharging your battery banks during harbour manoeuvres or while at anchor, while maintaining a compact size suitable for tight engine compartments.

Yes, this model is supplied as standard with the Alpha Pro III smart charge regulator. This regulator optimizes charging using a three-stage automatic algorithm (Bulk, Absorption, Float) to maximize battery life.

The alternator and its Alpha Pro III regulator are compatible with lead-acid (flooded), gel, AGM, and lithium-ion batteries.

The Alpha Compact 14/200 alternator absorbs a maximum power of 5.6 kW, which is equivalent to approximately 7.6 hp (horsepower) of load on your engine.

Absolutely. Thanks to its patented magnetic design and optimized cooling via integrated dual-fan system, it can withstand a maximum operating temperature of 120 °C.

The Alpha Pro III regulator automatically adjusts charging voltage based on temperature (-30 mV/°C for a 12 V system) using the included battery temperature sensor. This ensures safe and efficient charging.

No, Lithium-ion batteries do not require external temperature compensation. The supplied temperature sensor is primarily intended for lead-acid battery banks (flooded, gel, AGM).

This alternator features a very dense and compact design, weighing only 7.5 kg, which greatly facilitates installation in confined spaces.

Yes, the included Alpha Pro III regulator is fully compatible with the MasterBus network. It features two RJ-45 ports for real-time monitoring and advanced configuration from a centralized display.

The Alpha Compact 14/200 alternator is extremely mechanically robust and can support rotation speeds up to 20,000 RPM.

The positive output connection (B+) is made via two M8 terminals. It is crucial to tighten the connections to the recommended torque and use cables of the appropriate cross-section to avoid overheating or voltage loss.

No, the 14/200 model is specifically designed for 12 V systems (it delivers a nominal current of 200 A at 12 V). For a 24 V system, you should look at the 28/xxx series models.

Yes, the alternator is supplied with a 1.5-meter oil-resistant wiring harness, specifically designed for easy and secure connection of the Alpha Pro III regulator to the alternator.

By default (at 25 °C), the voltage during Bulk and Absorption phases is set to 14.25 V, and the Float voltage is 13.25 V. These values are fully adjustable via the MasterBus interface.

Yes, if an isolated mounting is required for your installation, you can use insulating sleeves (available as an option) to insert on each side of the mounting holes, and connect a specific ground cable lug.

The connection for the tachometer signal (W or RPM signal) is made very simply via an isolated quick-connect terminal (Faston tab) located directly on the alternator housing.

The D+ LED connected to the regulator serves as an alarm indicator. For example, 3 short blinks every 2 seconds on the D+ LED indicate an excessively high field current, while 2 blinks signal a battery voltage that is too high.

Yes, via the built-in alternator temperature sensor, the Alpha Pro III regulator will linearly reduce output power when the temperature reaches 85 °C and cut the load at 120 °C to protect the equipment from damage.

The Alpha Compact 14/200 is designed to deliver excellent output at low RPM. Its charging speed begins at just 1350 RPM (alternator rotation speed), enabling rapid charging even when the engine is idling.

For the MasterBus network, the power supply follows the rule of 1 powered device for every 3 non-powered devices. It is important to distribute the powered devices evenly across the line and never create a looped or ring network.
