Ecostab-Ecobuck

General features

Range. Voltage optimisers are available in power range from 5 to 4000 KVA, in single-phase and three-phase version.

• Single-phase 100-110-115-120-127-200-220-230-240-265-277V.
• Single-phase with input 240V and output 230V.
• Three-phase 208-220-230-240-380-400-415-440-460-480-500V.
• Three-phase with input 415V and output 400V.
• Frequency: 50 or 60 Hz.

Accuracy. Ecostab-Ecobuck voltage optimisers secure the true RMS voltage value with an accuracy of ±1% according to the presence of high harmonic distortions of the mains.

Regulation speed. An innovative control circuit combines an extremely fast regulation speed, from 11 to 33 ms/V according to the model, with the structural reliability of the electrodynamic system.

Overload capacity. This is a peculiarity of the Ecostab-Ecobuck electrodynamic regulation system. These devices can withstand overloads up to ten times the rated power for ten milliseconds, five times the rated power for six seconds or twice the rated power for one minute without damage.

Efficiency. Efficiency up to 98.5% at full load.

Power factor and load variation insensitivity. The adopted operating principle ensures that the accuracy and the regulation speed features of Ecostab-Ecobuck voltage optimisers remain unaltered under any load condition (full load or no load, with inductive or capacitive loads).

Frequency variation insensitivity. The control circuit works correctly also with mains frequency variations up to ± 5%.

Harmonic distortions. The high quality and correct use of materials ensure that the harmonic distortion is always maintained within 0.1% in any operating condition.

Impedance. The installation of an Ecostab-Ecobuck voltage optimiser in a pre-existing system does not require a new calculation of the protections because the internal impedance of the optimiser, varying from 0.52 to 0.015 Ohm, does not significantly affect the line impedance.

Operating temperature. Ecostab-Ecobuck voltage optimisers are designed to work correctly at a maximum ambient temperature of 40°C in the most demanding conditions: continuous operation, full load and minimum input voltage. Models suitable for operation at temperatures higher than 40°C are manufactured on request.

Degree of protection. According to the ambient conditions, the safety requirements and the installation site, Ecostab-Ecobuck voltage optimisers are available in 4 versions with the following protection degree: IP00, IP21, IP54 INDOOR and IP54 OUTDOOR.

Reliability.  The MTBF exceeding 500,000 hours is the result of continuous improvement in technical aspects and production process.

Cooling system. Ecostab-Ecobuck voltage optimisers are cooled in different manner according to the type of casing and the ambient conditions by means of:

• natural convection
• fans
• air conditioning

Installation. It is rather quick and easy. The voltage optimiser is installed after the energy counter and before the electric users.

Special versions. Ecostab-Ecobuck voltage optimisers can be equipped on demand with special fittings in separate cabinet, like e.g.: maintenance by-pass, thermal magnetic circuit breakers, insulating transformer, surge suppressors, lightning arresters, harmonic filters.

Remote control. Ecostab-Ecobuck voltage optimiers can be equipped with a special optional monitoring system POWER METER permitting the remote control via ETHERNET, INTERNET, GSM/GPRS. The following electric and physical parameters are detected: frequency, active power, reactive power, apparent power, distorting power, three-phase equivalent current, line current, power factor, active, reactive and inductive energy, harmonics, temperature, humidity, switch and contactor state. By using the POWER MANAGEMENT software installed on a non-dedicated PC, detected values can be managed and statistics can be obtained on a daily, weekly, monthly and yearly basis with various viewing, data processing, cost calculation and energy saving possibilities.

Compliance with standards. Ecostab-Ecobuck voltage optimisers comply with the following Directives:

• Electro Magnetic Compatibility 2004/18/EC and following amendments.
• Low Voltage Electrical Equipment 2006/95/EC and following amendments.
