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.
