ECOSTAB – ECOBUCK
VOLTAGE OPTIMISERS

IREM PROPOSAL

Sites equipped with an IREM Ecostab – Ecobuck voltage optimization system often obtain reductions of 5 to 15% in energy consumption, costs and, therefore, in carbon dioxide emissions!
The first step to evaluate the opportunity to install a network optimizer is to monitor and know the input voltage levels: the IREM Ecometer Energy Saving Meter allows you to determine the parameters.
The values displayed are calculated with the method recommended by the VDE-AR-E 2055-1 standard. The savings displayed guaranteeing the precision of the metrological chain of measuring instruments.

The IREM Ecostab – Ecobuck Voltage Optimisers are equipped with 2 digital network analyzers and an additional display that shows the energy savings achieved.
These multimeters display all the electrical parameters, such as voltage, current, frequency, power, power factor, total harmonic distortion etc., measured from the mains input, to the economizer output. These multimeters are characterized by:

• 128×80 pixel LCD graphic display, backlit;
• 4 keys for display and programming;
• Simple and fast navigation;
• Texts for measurements, programming and messages in 5 languages;
• True RMS Measurements (TRMS);
• Continuous data acquisition;
• High accuracy.

ENERGY SAVING
THROUGH ENERGY EFFICIENCY

The term Energy Saving includes various techniques aimed at reducing the consumption of energy necessary to carry out human activites.
Energy Saving can be achieved both by reducing energy processes so that less work is done, and by optimizing these processes so that, for the same work, less energy is required. This last way is that of Energy Efficiency.
The term Energy Efficiency indicates the ability of a physical system to obtain a given result by using less energy than other systems called less efficient, generally increasing its efficiency and allowing therefore energy saving and a reduction in operating costs.
“Energy Efficiency” indicates the ability to be able to “do more with less”, adopting the best technologies/techniques available on the market and a more conscious and responsible behavior towards energy uses. This therefore implies a more rational use of energy, eliminating waste due to operation and sub-optimal management of simple and complex systems.
The increase in energy efficiency is achieved by implementing forms of intervention that include technological improvements, optimization of energy management and diversification of energy supply. Wastes and energy losses represent the hidden “deposit” we have and that energy efficiency allows us to recover and valorise in order to obtain substantial economic, environmental and social advantages.
For these reasons, energy efficiency is the essential component of a virtuous energy strategy aimed at achieving a safer, more competitive and more sustainable low-energy economy.

Energy efficiency = “Do more with less”

Energy Efficiency for the environment: < CO2

Greater energy efficiency makes it possible to use less fossil fuels and therefore to reduce the level of greenhouse gas emissions, which contribute to global warming.

 

Energy Efficiency for companies: < OPERATING COSTS

With the increase in energy efficiency it is possible to reduce the energy expenditure of companies that can reinvest the money saved on core business activities to increase competitiveness on the market.

 

Energy Efficiency for the future: > AVAILABLE ENERGY

Energy Efficiency is the most universally available energy source. The most convenient and cleanest energy is energy that must not be produced or used.

VOLTAGE OPTIMIZATION

The average voltage value of the distribution networks is often greater than the ideal operating value for most electrical equipment.
For example, a 230 V linear load used with a 240 V power supply, absorbs 4.3% current more and it consumes 9% more electricity than the 230 V power supply.
A common but wrong belief relating to voltage optimization is that, reducing the voltage, leads to an increase in the current and, therefore, absorbed power remains unchanged.
This is true for certain types of loads, called constant power; however, most sites have a variety of loads that will benefit to a greater or lesser extent from energy savings by considering the whole site as a single unit.
Voltage optimization is a technique of energy efficiency which, by operating through the systematic and controlled reduction of the network voltage, allows to reduce the absorption from the active and reactive power network.
While some voltage “optimization” devices have fixed voltage regulation, others regulate the voltage automatically electronically. Voltage optimization systems are usually installed in series with a building’s electrical network, allowing all installed electrical equipment to benefit from an optimized power supply.
High voltage values lead to higher energy consumption than necessary and, consequently, higher electrical costs.
High voltage values are not only expensive, but can also be harmful to equipment. Excessive supply voltage produces noise, heat and further vibrations that stress internal components, in particular motors that are sensitive to overheating and wear out more quickly. The IREM Ecostab – Ecobuck voltage optimization system ensures that a user receives and pays only for the voltage actually needed and no more, they optimize power quality and generate energy savings.

ECOSTAB is a voltage stabilizer designed for Energy Saving and capable of improving Power Quality in all mains voltage conditions.
Ecostab supplies the load with a stable voltage having a value less than or equal to the nominal mains voltage.
The voltage with which the load is powered can be set through a potentiometer between the nominal value and -8%.

Ecostab is able to increase or reduce the voltage of the electrical distribution network in order to provide the loads with an optimal voltage, which can be set to a desired value and kept stable.
The desired value is linearly adjustable between a minimum value of 368V (-8%) and a maximum value of 400V (± 0%).
In the entire range of variation of the mains voltage allowed by the standard (± 10% of the nominal value of 400V) the load is always powered by the Ecostab at the desired voltage, kept stable at ± 1%.

ECOBUCK is a voltage stabilizer designed specifically for Energy Saving and capable of improving Power Quality in certain mains voltage conditions.
The Ecobuck supplies the load with a stable voltage having a lower value or at the limit equal to the nominal mains voltage.
The voltage with which the load is powered can be set through a potentiometer between the nominal value and -8%.

Ecobuck is able to reduce the voltage of the electrical distribution network in order to provide the loads with an optimal voltage, at a value lower than the nominal mains value.
The behavior of the Ecobuck differs from that of the Ecostab only when the mains voltage is less than the desired voltage.
In conditions of voltage lower than the desired value, the Ecobuck does not worsen the supply conditions, simply the load is powered at the voltage it would be powered on if there was no Ecobuck.
