Three-phase static voltage stabilizer 30–60 kVA, 400 V ±2 %
Country: Spain · Model: Static 3F
A three-phase static voltage stabilizer for 30, 45 and 60 kVA holds 400 V at the output with ±2 % accuracy on a 300–480 V input mains. Correction runs at 1000 V/s, so it is installed where fast response is needed, including CNC machines, packaging lines, refrigeration units, small plants, and commercial and office buildings with their own transformer room.

Description
The output voltage can be set to 380 or 415 V on request. A speed of 1000 V per second means that dips and surges are handled within a fraction of a cycle. Voltage is measured by a True RMS module sampling every 20 ms, control is microprocessor-based, and the boards are built as modules, so repairs are faster. The unit works with any type of load and recognizes non-linear loads and short circuits. During a short circuit the fuse does not blow, and once the cause is removed the stabilizer resumes operation by itself. A double overload is allowed for 10 s, and efficiency is above 97 %. The digital display shows input and output voltage, current, frequency and power, and the manual bypass makes it possible to service the unit without switching off the consumers. Cooling is natural with a thermostat, the enclosure is IP20, or IP54 on request. Operating temperature is up to 50 °C, installation altitude up to 3000 m, noise below 55 dB.
How to choose
Choose the rating with a 20–30 % margin over the full load power, and take motor starting currents into account separately, since the double overload for 10 s covers the start of most compressors and pumps. The load power factor is 0.8, or 1 on request. For ratings from 100 kVA the same series is made in an industrial version. If the mains sag heavily and speed is not critical, consider the three-phase servo-driven SRV33 for 6–60 kVA, which corrects at 90 V/s but introduces no harmonic distortion.

FAQ
What output voltage does the three-phase static stabilizer for 30–60 kVA hold?
400 V with ±2 % accuracy, and the output can be set to 380 or 415 V on request. The input mains can be 300–480 V at a frequency of 47–65 Hz.
Can it handle the start of a motor or compressor?
An overload of 200 % is allowed for 10 s, which is enough for starting motors and compressors.
What happens during a short circuit at the output?
The short-circuit and overload protection operates and the fuse does not blow. Once the cause is removed the stabilizer resumes operation by itself, and no fuse has to be replaced.
Can the stabilizer be serviced without switching off the consumers?
Yes, there is a manual bypass for this. The digital display shows input and output voltage, current, frequency and power.
What are the installation conditions and the warranty?
The enclosure is IP20 or IP54 on request, operating temperature is up to 50 °C, storage −25…+60 °C, humidity below 95 %. The warranty is 2 years, spare parts are supplied for 10 years, with CE marking and an ISO 9001 quality system (TÜV Austria Hellas).
