VOLTAGE OPTIMIZERS

ECOSTAB B

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 pre-existing 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.

OPERATING PRINCIPLE

IREM automatic voltage optimizer with common regulation of the three phases
IREM automatic voltage optimizer with independent regulation of the three phases

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.
