Description
The output voltage is set with an accuracy from ±1 to ±5 %, depending on the sensitivity of the equipment. The servo drive corrects a 10 % grid deviation to 2.5 % in 0.6 s. TVSS and class II SPD protect against surges, so lightning spikes at the supply do not reach the load. The H version works on 220–240 V grids and the L on 100–127 V grids. Efficiency is at least 98 %, that is, no more than a few hundred watts are lost for every 10 kVA of load. The IP20 enclosure is placed in a switchroom, and with the IP54 option the unit can be placed in a dusty room.
How to choose
Compared with the static ESR for 3–100 kVA, the SVS series has a narrower input range (±40 % against ±50 %) but lower losses, with 98 % efficiency against 95 %. For a three-phase supply there is the ESR-3P-T1F for 6–400 kVA. Choose the model by the full power in kVA with a margin for starting currents.

FAQ
What accuracy does the SVS stabiliser provide?
Accuracy is adjustable from ±1 to ±5 %, and the narrower setting is used for sensitive electronics.
What grid deviation can the SVS withstand?
The stabiliser works with an input voltage deviation of up to ±40 % of the nominal, which covers typical dips in suburban grids.
Does the SVS have overvoltage protection?
Yes, the built-in TVSS and class II SPD suppress surges at the input.
How does the SVS differ from the static ESR?
The SVS regulates with a servo drive, smoothly and with efficiency of at least 98 %. The ESR is fully electronic, without moving parts, with a range of up to ±50 %.
Can the SVS be installed in a dusty workshop?
For this order the IP54 option, as the basic IP20 enclosure is designed for a clean room.
