Voltage Optimizers EcoStab

Product Description

VOLTAGE OPTIMIZERS ECOSTAB 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.
