SH voltage stabilizer 100 VA – 5 kVA
Country: Italy · Model: SH
The SH single-phase stabilizer, rated from 100 VA to 5 kVA, holds the output voltage with ±2% accuracy. It is installed next to an individual consumer, for example a controller, a measuring instrument, a server rack or a boiler.

Description
The range consists of models SH-1…SH-10; the input is rated for 220/230/240 V ±20%, and for 100–127 V networks the manufacturer makes a version to order. The total harmonic distortion at the output is below 3%, so the stabilizer suits electronics with switch-mode power supplies and measuring circuits. The response time is 0.01–0.04 s, so short mains dips are almost unnoticed by the consumer. Efficiency at full load is 75%, part of the power is dissipated as heat, and free space for cooling is needed around the enclosure. The IP20 enclosure is intended for indoor use, and the unit meets CE and IEC 742 requirements.
How to choose
The SH rating is chosen from the rated power of the consumer with a margin for starting currents, especially for pumps and compressors. When the load exceeds 5 kVA or a three-phase input is needed, move to SE, with a range of 1–75 kVA single-phase and 3–2000 kVA three-phase, where efficiency reaches 98%. For sensitive lines that also suffer from mains interference, the CR power conditioner is suitable.

FAQ
What power do SH stabilizers have?
The SH-1…SH-10 range covers 100 VA – 5 kVA in single-phase versions.
What is the output voltage accuracy of the SH stabilizer?
The output is held within ±2% with total harmonic distortion below 3%.
Is there an SH version for 100–127 V networks?
Yes, the standard input is 220/230/240 V ±20%, and a 100–127 V version is made to order.
Why is the efficiency of the SH stabilizer 75%?
This is the value at full load for a low-power unit. Losses turn into heat, so the stabilizer is not placed in a closed niche without ventilation.
How fast does SH respond to a voltage change?
The response time is 0.01–0.04 s, so short mains dips are compensated almost unnoticed by the consumer.
