PARALLEL OPERATION FOR GENSET

This is a item for synchronization, manufactured and researched by Mecc Alte. This Mecc Alte accessory TTTT allows the technician to intervene to adjust the voltage as well as the basic parameters of the alternator.

1.1. MECC ALTE PARALLEL DEVICE – PD 500

ACCESSORIES-MECC-ALTE-1

The parallel device (PD 500) is a unified module that allows alternator to operate in parallel with each other at typical reduced voltage or with constant voltage.
Parallel device (PD) is fitted as standard on generator series 40 – 43 – 46; for other series, it will be installed upon request. (See Parallel Operation Manual or Grid Guidelines for further information.)

1.2. MECC ALTE PARALLEL DEVICE INTERFACE – PDI

ACCESSORIES-MECC-ALTE-2

The Parallel Device Interface (PD-I) is a module that allows alternator and regulator communication. It receives information such as voltage input, alternator sensor and sends it to the AVR for adjustment.
The DROOP regulator allows fine tuning of the PD voltage drop, with a maximum range of 0 to 8% of the reference voltage, depending on the generator and specific load conditions.


ENVIRONMENTAL INSULATION SYSTEM OF ALTERNATOR

In order for the Mecc Alte alternator to be used in many different harsh environmental conditions, we need to equip additional accessories to support operation, maintain performance as well as avoid direct damage on the quality and durability of the alternator. Harsh environmental conditions can be mentioned such as: Sea salt vapor environment, condensate steam, hot sunny environment, desert or environment containing dangerous substances, radio waves… Let’s find out with TTTT The following supporting accessories are included:

2.1. MECC ATLE ANTI CONDENSATION HEATER

ACCESSORIES-MECC-ALTE-3

Our entire range can be equipped with anti condensation heater of a capacity to match the kVA of alternator.

The voltage for the heater must be specified when ordering. New cylindrical cartridge heaters are available upon request.

2.2. MECC ALTE INSULATION SYSTEM

ACCESSORIES-MECC-ALTE-4

The Mecc Alte alternator insulation system uses Class H insulation as standard, but with an additional coating of EG43 gray varnish, which is a high temperature insulating enamel, which will protect the transmitter from moisture. and chemical penetration.
GRAY protection level is now standard for dynamo over 85kVA. If you use alternator in a harsher environment, you can further enhance this level of insulation protection. Protection level TOTAL+ uses a black plastic compound, which is the ultimate winding treatment and offers outstanding protection in really harsh environments. This rubber-like protective layer wraps the coils and protects them from moisture and chemical attack. In addition, it is also resistant to grain abrasion as it deflects any impact.

2.3. MECC ATLE INTAKE AIR FILTER

ACCESSORIES-MECC-ALTE-5

The environmental conditions for the Mecc Alte alternator are extremely diverse. There are some very limited standards regarding the degree of protection of machinery to which in certain cases must be applied. As standard, the Mecc Alte range is IP23, however upgrade systems are available to comply with IP23+, IP43 and IP45 of the IEC standard.

2.4. MECC ALTE RADIO INTERFERENCE SUPPRESSOR – RIS

ACCESSORIES-MECC-ALTE-6

The Mecc Alte radio interference suppressor complies with major standards for radio suppression. To comply with even more restrictive standards such as Mil STD 461 required by the customer, special filters need to be installed in the alternator.

2.5. TOTALLY ENCLOSED AS IP54 & IP56 PROTECTION STANDARDS

Although not available as an accessory to retrofit, we can offer totally enclosed (TEFC) machines. These comply with IP54 protection standards and even IP56


 MECC ALTE ALTERNATOR THERMAL PROTECTION

Thermal protection accessories are an integral part of a Mecc Alte alternator. They have protection mechanisms and functions, which help prevent overheating, sudden overloads that seriously affect the quality and performance of the dinamo. On request, it is possible to install one of the following devices as thermal protection

3.1. PTC THERMISTORS

These components are assembled in the ends of the stator windings. They are usually set to travel at 150°C. When the preset temperature is reached, the thermistors emit a signal that can be used by a trigger device to protect the alternator.

3.2. THERMAL RESISTORS

3.2.1. PT100

The resistance of this device varies proportionally to the temperature of the coil where it is assembled. If combined with a thermostat, it allows the temperature to be set to the desired value at which the entire protection system will operate.

3.2.2. BIMETALLIC OVERLOAD PROTECTIONS

These devices have “Normally Closed” contacts that will operate immediately when the preset temperature is reached. If the temperature drops, the alignment will reset automatically.


ALTERNATOR ADDITIONAL EQUIPMENTS

4.1. MECC ALTE CURRENT TRANSFORMER – CT

ACCESSORIES-MECC-ALTE-7

Mecc Alte offers on ECO 40, 43 and 46, a range of current transformer pre-installed on the alternator. We can supply current transformers to customer specifications, for protection or measurement or even with dual outputs.

4.2. DLI AND DXR – MECC ALTE INTERFACE DEVICE

ACCESSORIES-MECC-ALTE-8

The interface device allows the connection of the AVR voltage regulator to a software on computer or a PLC monitoring device. It can connect with RS232, USB or RS485 protocols.
If using a computer, Mecc Alte provides this software solution to monitor and fully program its voltage regulator, is an AVR terminal and an AVR reader.

4.3. MECC ALTE PERMANENT MAGNET GENERATOR – PMG

ACCESSORIES-MECC-ALTE-9

The permanent magnet generator system allows an additional set of PMG tools to be fitted to an existing detector. This means that the MAUX backend can act as standby in the event of a problem. No need to change the AVR, a kit can be kept in stock and retrofitted to our generators above 400kVA. From 180kVA to 350kVA (50Hz), PMG is only suitable for factory. Overload and transient response performance is the same as for MAUX and is shown in the machine’s data sheet.

The Mecc Alte PMG is available on the ECO38 as a factory-installed option or on the ECO40, ECO43 and ECO46 as a factory-installed or second-hand option.


MECC ALTE PORTABLE ALTERNATOR ACCESSORIES

ACCESSORIES-MECC-ALTE-10

5.1. ECOLOGIZER ECO1/ECO2

In the case of power reduction, the ecologizer is a device allows control the transmission, acts on the engine control unit to reduce its speed and allow to reduce fuel consumption, cell atmospheric and acoustical contamination.

5.2. REGULATOR RCM/2

A patented electronic device designed to improve the output voltage accuracy on a capacitor-driven a.c of alternator.
This allows the alternator to achieve higher efficiency as far as voltage stability is concerned, regardless of changes in engine speed, load conditions and temperature.

5.3. BATTERY CHARGING WINDINGS

All alternators are available with battery charging coils and optional 12V direct current (DV) batteries with charging terminals.

5.4. TWO BEARING KITS

For the small range of alternators, a kit can be purchased that can be retrofitted to the alternator to create two parallel keyway bearings and add front legs.

5.5. END COVERS

A wide variety of end caps with sockets, circuit breakers and switches are available. Schuko and CEE sockets can be fitted to end caps in several variations to allow quick and easy assembly.

5.6. TOP BOXES

Many variations of the top box are available equipped with sockets, circuit breakers and toggle switches. They can be mounted directly to the alternators.

5.7. INGRESS PROTECTION

The alternator ingress protection meets IP21 standard. Kits or upgrade options for IP23 and IP45 are available on most models. Depending on the needs of customers, we will support upgrading to create the best quality products.
