Description
The industrial range of three-phase static voltage stabilizers covers powers from 100 to 2000 kVA: 100, 150, 200, 300, 500, 800, 1250, 1600 and 2000 kVA. Such units are installed at the incoming supply of a workshop, plant, logistics centre, hospital or data centre, after a 6(10)/0.4 kV transformer, when the mains voltage is unstable and the whole facility needs protection rather than a single machine. The input voltage range is 300–480 V, the output is 400 V with an accuracy of ±2 %, and 380 or 415 V on request. The regulator corrects deviations at 1000 V/s, so it levels both fast dips during the starting of powerful motors and slow daily fluctuations. Measurement is True RMS with sampling every 20 ms, control is microprocessor-based, and the electronics are built from replaceable modules. The stabilizer works with any load, including non-linear, and can distinguish it from a short circuit. In the event of a short circuit, electronic protection operates, the fuse remains intact, and after the cause is removed the unit returns to operation. Overload capacity is 200 % for 10 seconds, and efficiency is above 97 %. A manual bypass is provided for maintenance. The display shows the input and output voltage, current, frequency and power. Cabinets are IP20, IP54 on request; cooling is natural with a thermostat; operation is permitted at temperatures up to 50 °C and at altitudes up to 3000 m; noise is below 55 dB. The equipment is marked CE, and the manufacturer's quality system is certified to ISO 9001 (TÜV Austria Hellas). Warranty is 2 years, spare parts 10 years. Units of this range are usually installed in a separate electrical room next to the main distribution board. When selecting, the total load power, starting currents and the range of mains fluctuations at the site are taken into account. For these powers, the stabilizer is selected on the basis of mains measurements over several days: the depth of dips, their duration and phase imbalance are important.
