SVS — single-phase 230 V stabilizers 0.5–5 kVA
Country: United Kingdom · Model: SVS
SVS single-phase solid-state 230 V stabilizers are made in ratings from 0.5 kVA (4 A) to 5 kVA (20 A). They feed refrigeration equipment, air conditioners, computers and satellite receivers where the mains voltage is unstable.

Description
The output holds 230 V with an accuracy of ±6 %. When the input voltage falls below 142 V or rises above 295 V, the stabilizer switches the load off, that is, the built-in AVS function works as a voltage relay. After the mains returns, power is supplied with a start delay, and TimeSave does not add an unnecessary pause if the mains was absent longer than the delay time. The circuit has no moving parts, no brushes and no servo motor, so it reacts quickly and does not wear out. Against surges, spikes on restoration and lightning the unit gives basic-level protection; it does not replace a full SPD at the entry. The top model SVS20 is designed for fixed connection to the wiring, the smaller ones plug into a socket.
How to choose
The rating is selected by the starting power, which for a refrigerator or air conditioner is several times the running power. For a PC and a TV 0.5 kVA is enough; for an air conditioner or a group of appliances take the 5 kVA model. If the mains regularly sags below 142 V, it is better to look at the SVS…-22E with a 110–305 V input, and for protecting a whole house at the wall-mounted SVS WM.

FAQ
At what voltage does the SVS stabilizer switch the load off?
Cut-off occurs if the input voltage is below 142 V or above 295 V. After the mains normalizes, power returns with a start delay.
What output accuracy does the single-phase SVS stabilizer give?
The output voltage is 230 V with ±6 % accuracy, which is sufficient for household and office equipment.
Which SVS model is connected permanently?
The 20 A SVS20 is designed for fixed connection to the electrical wiring. The smaller models from 4 A (0.5 kVA) work from a socket.
Does the SVS stabilizer protect against lightning overvoltages?
It has basic lightning protection and suppresses surges and spikes when the mains is restored. At high-risk sites a separate SPD is installed in front of it.
