MACHTMANN MN18000WD-ATS is a three-phase power generator designed for emergency power supply and operation in places without access to the power grid. The generator provides a voltage of 400 V for three-phase receivers and 230 V for single-phase devices.

The rated power of the generator is 13 kW, while the maximum power reaches 14 kW. With a power factor of cos φ 0,8, the maximum power of 14 kW corresponds to 17,5 kVA, which is why the model is commercially offered as an 18 kVA class unit.

The DualPower function allows you to switch the unit to a 230 V reinforced single-phase power supply mode. The solution increases the usability of the device when it is required to power more powerful single-phase receivers, and not just evenly distributed three-phase devices.

The team drives a 2V95 two-cylinder diesel engine in a V system. The unit is air-cooled, has an electric start and works with the SmartGen digital control panel. The closed housing reduces noise levels and protects the motor, generator and electrical systems from accidental damage.

The rated power of the unit is 13 kW. This is the basic power level designed to regularly power receivers while maintaining appropriate cooling conditions and proper operation of the device.

The maximum power is 14 kW and is a short-term reserve available when taking over the load or starting selected devices. The unit should not be loaded with full maximum power for a long time.

With a power factor of cos φ 0,8, the parameters correspond approximately to:

• rated power: 13 kW / 16,25 kVA,
• Maximum power: 14 kW / 17,5 kVA.

The term ‘18 kVA’ used in the product name is the rounded trade name of the power class of the device.

When selecting an aggregate, account should be taken of:

• active and apparent power of receivers,
• power factor of equipment,
• starting currents of electric motors,
• method of starting pumps and compressors,
• occurrence of inverters or softstarts,
• asymmetry of phase load,
• possibility of simultaneous operation of receivers,
• consumable stock required.

With a rated power of 13 kW, a voltage of 400 V and a power factor of cos φ 0,8, the calculated three-phase current is about 23,5 A:

13 000 IN ÷ (√3 × 400 V × 0,8) ≈ 23,5 A

For a maximum power of 14 kW, the calculated current is about 25,3 A.

The 400 V / 32 A socket used has sufficient current capacity to use the declared power of the unit, provided that the load is properly distributed, the correct power factor of the receivers and the parameters provided by the manufacturer are maintained.

MACHTMANN MN18000WD-ATS has a DualPower function, allowing you to switch the way the generator works and increase the power supply capabilities of single-phase receivers.

In a typical three-phase aggregate, the power available on a single 230 V phase is much less than the total generator power. DualPower allows you to use most of the potential of the unit at a single-phase output.

The solution is particularly useful during power supply:

• power tools 230 V,
• heating devices,
• single-phase pumps,
• compressors,
• refrigeration equipment,
• workshop equipment,
• prepared house circuits,
• catering equipment,
• equipment used on construction sites.

The maximum power received by a single socket remains limited by its rated current. The 230 V / 32 A socket allows you to theoretically receive about 7,36 kVA, while the 230 V / 16 A socket about 3,68 kVA.

Switching between three-phase mode and DualPower should be done according to the instructions of the device, preferably without a connected load.

The heart of the unit is a four-stroke, two-cylinder 2V95 diesel engine. The cylinders are set in a V system, which allows you to obtain a compact unit design while maintaining the power appropriate for the generator of this class.

The declared engine power is about 26 hp. The unit uses diesel and has been adapted to drive a generator in a transport aggregate.

The two-cylinder design provides a more even operation than the single-cylinder diesel engines used in smaller units. The motor has an electric starter, thanks to which the start-up is carried out using a ignition and a control panel.

The 2V95 engine is air cooled. The system uses a fan that forces air flow around the components of the drive unit.

Air cooling simplifies the design of the unit because the unit does not require a radiator, liquid pump, pipes or periodic replacement of coolant.

During operation, however, it is necessary to ensure free air flow through the housing. Not allowed:

• cover ventilation openings,
• set the working unit directly against the wall,
• allow hot air to be sucked back in,
• use the device in a closed, non-ventilated room.

The unit should work outside, in a place protected against the accumulation of exhaust gases.

MACHTMANN MN18000WD-ATS has an electric starting system. Starting the engine is carried out using a starter and a 12 V battery.

The kit is offered with a 12V/30Ah starter battery. In the emergency installation, you should regularly check:

• state of charge of the battery,
• charging voltage,
• cleanliness of terminals,
• connections of wires,
• the action of the starter,
• fuel and oil levels,
• readiness of the control system.

Long-term leaving the unit without starting can lead to battery discharge. The device should be periodically tested under load.

The unit has a diesel tank with a capacity of 30 l and a fuel level indicator. This allows you to control the fuel supply without opening the tank.

There are two different combustion values in current commercial materials:

• about 2,8 l/h as average consumption,
• about 1,1 l/h at full load in the descriptive part.

For a unit of this class, a value of about 2,8 l/h is more realistic, but the actual combustion will depend on the load, operating mode, temperature, filter status and characteristics of the powered devices. The discrepancy is described in detail in the comments before publication.

With an average consumption of about 2,8 l/h, the theoretical working time on a 30-liter tank is about 10 hours. Actual time will depend on the useful capacity of the tank and the load level.

The generator has a winding made of 100% copper. Copper provides good electrical conductivity, adequate thermal resistance and proper operating conditions of the generator under load.

The generator produces:

• three-phase voltage 400 V,
• single-phase voltage 230 V,
• frequency 50 Hz,
• 12 V constant voltage.

The declared degree of protection of the generator is IP23. This designation refers to the protection of the electrical components of the generator, and not to the full water resistance of the entire unit.

The unit is equipped with an automatic AVR voltage regulator. The system controls the excitation of the generator and corrects the voltage during load changes.

AVR improves power conditions, among others:

• electronics and household appliances,
• refrigerators and freezers,
• central heating furnaces,
• pumps,
• computers,
• power tools,
• monitoring systems,
• lighting,
• electronic controllers.

AVR stabilizes the voltage, but does not turn the device into an inverter unit. The frequency of energy depends on the engine speed, and the quality of power supply can change during the rapid takeover of heavy load.

MACHTMANN MN18000WD-ATS is equipped with a SmartGen digital control panel. The controller enables operation of the unit and monitoring of basic generator operating parameters.

The declared parameters of the panel include:

• Nixie Tube LED Display,
• operating panel made in PET technology,
• one digital input,
• two relay outputs,
• two analog inputs,
• operation of alternator voltage from 30 to 360 V phase-neutral,
• support for 50/60 Hz frequency,
• programming via the LINK interface,
• 9 to 18 V DC power supply,
• operating temperature range from –25 to +70°C.

The exact symbol of the controller used is not indicated in the current product sheet.

The MN18000WD-ATS designation indicates the version prepared to cooperate with the ATS/SZR automatic backup power supply system.

The ATS/SZR is optionally available and can perform the following sequence:

1. control of mains supply voltage,
2. detection of decay or incorrect network parameters,
3. transmission of the start-up signal to the unit,
4. engine start-up,
5. control of generator parameters,
6. switching the installation to power from the aggregate,
7. monitoring the return of mains voltage,
8. switching receivers back to the network,
9. stop the aggregate after the end of the work cycle.

The aggregate panel includes:

• 1 socket 230 V / 16 A,
• 1 socket 230 V / 32 A,
• 1 socket 400 V / 32 A,
• 1 output 12V/8A with rectifier function,
• thermal protection of the 12 V circuit,
• ignition switch,
• protection of circuits,
• voltage indicator.

The 400 V / 32 A socket allows you to theoretically receive:

√3 × 400 V × 32 A ≈ 22,2 kVA

Its load capacity is therefore higher than the maximum aggregate power of 17,5 kVA. However, the full use of power remains dependent on the uniform phase load and characteristics of the connected receivers.

The motor, generator and electrical systems were placed in a closed silencing housing. The design reduces noise emissions and protects the device components from accidental contact and damage.

The declared acoustic parameters are:

• sound pressure level LpA: about 75,1 dB(A),
• LwA sound power level: about 97 dB(A).

The housing should not be referred to as completely waterproof. During outdoor use, the device should be protected from intense rainfall, flooding and water accumulation, while maintaining free ventilation.

The dimensions of the unit are approximately:

• length: 1240 mm,
• width: 672 mm,
• Height: 740 mm.

The weight of the unit is about 320 kg.

Due to the weight of the device, it is not an aggregate designed to be manually carried by one or two people. Transportation should be carried out using appropriate equipment, using the provided points or transport hook.

The set includes:

• generator set,
• 12 V / 30 Ah battery,
• battery mounting kit,
• eye wrench,
• transport hook.
