Alpha Compact 14/200-es generátor a Mastervolt Alpha Pro III-mal

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

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

The Alpha Pro III alternator and its regulator are compatible with lead-acid batteries (flooded), Gel, AGM, as well as 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 fans, it can withstand a maximum operating temperature of 120 °C.

The Alpha Pro III regulator automatically compensates for charging voltage based on temperature (-30mV/°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 temperature sensor provided 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 its installation in confined spaces.

Yes, the included Alpha Pro III controller 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 withstand 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 to use cables of the appropriate cross-section to prevent overheating or voltage drop.

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 must choose models from the 28/xxx series.

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

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

Yes, if an insulated 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 dedicated earth cable lug.

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

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

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

The Alpha Compact 14/200 is designed to deliver excellent output at low RPM. Its generation speed starts 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.
