VOLTAGE OPTIMIZERS

ECOBUCK

SINGLE PHASE M AND THREE-PHASE T / Y
GENERAL FEATURES
POWER RANGE From 8 to 2800 kVA, in single-phase and three-phase version.
ACCURACY ±1% RMS also in presence of high harmonic distortions.
OVERLOAD CAPACITY 10 times the rated power for 10 ms, 5 times for 6 s, 2 times for one minute
EFFICIENCY Exceeding 98.5%.
POWER FACTOR AND LOAD VARIATION INSENSITIVITY The accuracy and the regulation speed remain unaltered under any load condition (full load or no load, with inductive or capacitive loads).
FREQUENCY VARIATION INSENSITIVITY
HARMONIC DISTORTIONS The harmonic distortion is always maintained within 0.2% in any operating condition
IMPEDANCE The installation of an Ecostab voltage optimiser in a preexisting plant does not require a new calculation of the protections because the internal impedance of the optimiser does not significantly affect the line impedance.
OPERATING TEMPERATURE Ecostab voltage optimisers are designed for operation at a maximum ambient temperature of 40°C in the most demanding conditions: continuous duty, full load and minimum input voltage. Models suitable for higher temperatures are manufactured on request.
DEGREE OF PROTECTION IP00, IP21, IP54 INDOOR and IP54 OUTDOOR
COOLING SYSTEM All IP21 models are designed for natural air convection – FAN-FREE. IP54 models are cooled by fans or by air conditioning depending on the ambient conditions.
RELIABILITY Ecostab voltage optimisers use the same technology and the same components as Ministab and Sterostab voltage stabilisers, that IREM has been manufacturing for over 60 years. The MTBF exceeding 500,000 hours is the result of IREM continuous improvement in technical aspects and production process.
INSTALLATION The voltage optimiser is installed after the energy counter and before the electric users.
STANDARD FITTINGS Digital network analyser / energy meter, pilot lamps, potentiometer, alarm indication and dry contacts for connection to an external device for protection against: overload, over/under voltage
SPECIAL VERSIONS Ecostab voltage optimisers can be equipped on demand with special fittings in separate cabinet, like e.g.: maintenance bypass, thermal magnetic circuit breakers, surge/lightning arresters, harmonic filters.
REMOTE CONTROL Ecostab voltage optimisers can be equipped with an optional monitoring system permitting the remote control via ETHERNET, INTERNET, GSM/GPRS.
COMPLIANCE WITH STANDARDS

Ecostab voltage optimisers comply with the following Directives:

  • Electro Magnetic Compatibility 2014/30/UE and following amendments
  • Low Voltage Electrical Equipment 2014/35/UE and following amendments.

HIGHLIGHTS

Power Quality: VOLTAGE OPTIMIZERS IREM
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%.
Power Quality: VOLTAGE OPTIMIZERS IREM
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.
Power Quality: VOLTAGE OPTIMIZERS IREM
The electric user is powered by the Ecobuck with a stabilized voltage when the mains voltage is greater than the output voltage set on the Ecobuck itself. When the voltage of the electrical network is lower than the set voltage value, the Ecobuck does not make any corrections, consequently the load is powered by the mains voltage. For example, if you want to select a supply voltage of 380V equal to -5% of the nominal voltage of 400V, the selected voltage value is kept constant in the range of the input voltage variation between 380V and 440V.
If the mains voltage drops to 375V, for example, the Ecobuck would deliver 375V to the load. As soon as the mains voltage returns to a value higher than the set value (for example 382V), the Ecobuck returns to operate by adjusting the voltage on the load.

IREM voltage optimisers are designed to deliver the declared power permanently (24/7) under the worst operating conditions, i.e. at full load, at minimum ECOSTAB S SINGLE PHASE M AND THREE-PHASE T / Y input voltage and max input current and at the declared ambient temperature

An electronic control circuit detects the voltage delivered by the voltage optimiser and compares it to a reference voltage. If the difference between the output voltage and the reference voltage exceeds the preset tolerance limits, an error signal is generated; this signal may be either negative or positive according to whether the output voltage is lower or higher than the preset value. This signal activates the servomotor which moves the mobile contacts (electrographite rollers / brushes) of the variable autotransformer thus changing the transformation ratio in order to supply the additive or subtractive voltage needed to restore the value within the predetermined limits to the primary winding of the series transformer. The rootmean-square value (RMS) of the output voltage is stabilised and consequently not affected by possible harmonic distortions present in the input mains. This regulation system has the advantage of not having mobile contacts in series to the power supply line.
