BlackStone OFB 4000 D - 3.1 kW Diesel Power Generator with AVR - DC 2.8 kW Single-phase

The Blackstone OFB 4000 D electric single-phase generator is a product that can be used in the field of construction, agriculture and domestic. The simple and intuitive controls and its reduced size make it easy to transport so that you can always aver power wherever needed.

This model mounts a 4 stroke diesel engine with a displacement of 296 cc capable of emitting a maximum power of 5..4 HP. The engine respects the European EURO 5 legislation.

The alternator features a copper winding allowing the generator to reach a maximum output power of 3100W.

Equipped with AVR board: the current generator has an electronic card that automatically adjusts the output voltage, keeping it constant under varying load conditions

Finally, you can separately purchase the kit with wheels and handles to be installed on the generator to make it even easier to transport also increasing accordingly the usability.

WARNING: all these models of generators that do not belong to the PROFESSIONAL series (considering the product level evaluation used by our website) are not intended for more than 3-4 hours continuous work in order not to reduce the alternator durability as well as that of one of the other machine components due to the unit overheating or wear. As regards a home or intensive use of these generators, it is important to follow the indications mentioned above. In all these conditions, we highly recommend focusing the attention on the purchase of generators renowned as PROFESSIONAL by the product level classification made in our website.

The alternator of the generator is built with copper winding

Maximum single-phase nominal power* emergency conditions LTP: 3.1KW

* in case of an emergency the generator can reach this maximum power

Nominal single-phase power* in continuous running PRP: 2.8KW

*This is the data that should be taken into consideration as an effective and constant data for the generator output (it guarantees the product an infinite duration)

The Blackstone generator is equipped with AVR board: an electric device which automatically regulates the output of tension, making it constant as the load varies.

It also comes with resistant grommets ensure that the alternator to the frame.

Engine specifications:

Model: D300
Type: 4 stroke, single cylinder
Displacement: 296 cc
Power: 5.4 Hp
Fuel: diesel
Tank: 14 L

The gas-regulating and the acceleration of the engine is made in a automatic manner via the AVR card to vary the load connected.

As far as the needed power is concerned, we now provide you with an handy chart to help you navigate among consumption, starting coefficients and watt.

The best criteria is to pinpoint first which are the instruments we need to power with the generator and, consequently perform a simple calculation, as explained below, to identify the needed power that the generator need to eject.

Power required = Electric appliance consumption X Breakaway starting coefficient

The starting coefficient is a fundamental characteristic of any instrument which works with electric current because it indicates how much the consumption of the object increases. Therefore, this is needed to concretely determine how many WATT are necessary during the start up operations.

Example: Compressor (1500 Watt ) X Starting coefficient (2) = 3000 Watt Hence you should orientate towards a generator which has a WATT power equal or superior to the result (*)

Check the consumption of the appliance on the instruction and maintenance manual or on the plate attached to the machine.

WARNING: the chart is purely indicative. Thanks to the formula above you can easily calculate the power a generator should deliver to connect and start some specific products and select the model of generator which best suits your needs.

• The generator can be exclusively used to power single electrical appliances (with respect to the produced KW power in relation to the absorption during the starting phase that must be lower than the power supplied by the generator).

• The generator can be used to power household device in emergency conditions (no current service provided by the domestic household), exclusively on the models that are specifically provided with ATS (Automatic Transfer Switch) device (specifically designed for this purpose and provided with connecting systems to your household electrical power).

• The generator was NOT designed for PROFESSIONAL use, it is therefore apt for occasional use (not frequent). The working sessions must no be over 3-4 continuous hours (which would cause the alternator to overheat and wear, especially in its internal components rotor and stator) If you need a generator for frequent use (for example once a week), the user should look towards another type of generator, specifically intended for a frequent use and precisely a PROFESSIONAL or even INDUSTRIAL quality-level generator (that is not provided with a standard 3000 rpm alternator as this models is, but one which is designed with a professional alternator with low speed; 1500 rpm - with liquid-cooled engine and alternator - which have a level of specific characteristic and price point very different from this model’s);

The generator is not designed to be installed in photovoltaic or solar energy systems for energy production nor for the recharging or maintenance of batteries of these specific or other electric systems. Indeed, it may damage seriously the generator on its internal components (alternator, engine and electrical component). Each photovoltaic system requires a generator for INDUSTRIAL use (not for domestic use as this present model), specifically designed and manufactured for this purpose. WE DO NOT PROVIDE WARRANTY on generators connected to photovoltaic systems, as this entails an IMPROPER USE OF THE UNIT.

You can also buy among the accessories, the kit consists of wheels and handles to be applied to Blackstone current generators. This will allow all operators to be able to carry the generator with much greater simplicity minimizing any kind of stress due to the transport of the machine.
