Single-phase static voltage stabilizer 5–50 kVA, 220 V ±3 %
Country: Spain · Model: Static 1F
The single-phase static stabilizer for 5–50 kVA holds 220 V at the output with ±3 % accuracy and handles voltage changes at 1000 V/s. It is chosen for loads sensitive to response speed, for example medical and laboratory equipment, servers, cash and retail systems, control systems, single-phase machines and boiler equipment in houses and small businesses.

Description
The power section is static with no moving parts, and switching is controlled by a RISC microprocessor. A speed of 1000 V per second makes it possible to handle even short dips caused by the start of powerful neighboring consumers. The nominal input range is 160–250 V, and the working range extends to 130–260 V. An overload of 200 % is allowed for 10 s and 500 % for 20 ms, so starting current surges do not switch the unit off. Electronic protection operates on short circuit, overvoltage and overcurrent, a circuit breaker is fitted at the input, and indicators show the load level and the input and output voltage. There is no galvanic isolation between input and output, and if needed the stabilizer is complemented with an isolation transformer. Efficiency is above 97 %, cooling is natural with a thermostat, the enclosure is IP20 or IP54 on request, and a manual bypass is provided. Operating temperature is up to 50 °C, altitude up to 2000 m, noise below 50 dB.
How to choose
The range of ratings is 5 / 7.5 / 10 / 15 / 20 / 25 / 30 / 40 / 50 kVA. For a house with a single-phase supply 10–15 kVA is usually enough, and for a shop or small production site 20–50 kVA. Take the full power of all consumers operating at the same time with a 20–30 % margin, and account for motor starting currents separately. If the input voltage drops below 130 V, look at the single-phase servo-driven SV for 2.5–50 kVA with a 90–285 V input, but its correction speed is only 90 V/s.

FAQ
What is the input voltage range of the single-phase static stabilizer?
The nominal range is 160–250 V, the working range extends to 130–260 V, and the output is 220 V ±3 %. Mains frequency is 47–65 Hz.
What overload can it withstand?
200 % for 10 s and 500 % for 20 ms. This is sufficient for starting current surges.
Is there galvanic isolation between input and output?
No. If isolation is required, the stabilizer is complemented with an isolation transformer.
What is the advantage of a static stabilizer over a servo-driven one?
Speed, that is 1000 V/s against 90 V/s for the SV model, and in addition the power section has no moving parts. On the other hand, the input range is narrower.
What is the ingress protection class and the certification?
The enclosure is IP20 or IP54 on request, with natural cooling and a thermostat. It has CE marking and an ISO 9001 quality system (TÜV Austria Hellas).
