SVS-3P — three-phase servo-electronic voltage stabiliser 6–600 kVA
Country: United Kingdom · Model: SVS-3P
The SVS-3P series has 27 three-phase servo-electronic stabilisers from 6 to 600 kVA that work with grid deviations of up to ±40 %. Each phase is regulated separately, so the unit is installed at the supply of a workshop, office building or boiler house with uneven load across phases.

Description
The phases are regulated independently, and voltage imbalance between them is not carried over to the output. Accuracy is set from ±1 to ±5 %, with a narrow tolerance used for electronics and a wider one for motors and heaters. The grid options are designated by pairs of letters: H/HD for 380–415 V, LY/LD for 190–240 V and HX/HXD for 440–480 V. Most models can be ordered as a power conditioner with an isolation transformer that filters noise in front of sensitive equipment. Efficiency is at least 98 %. The IP20 enclosure is for an electrical room, and the IP54 option is for rooms with dust.
How to choose
Among the 27 ratings, select the nearest one above the calculated supply power in kVA. If the absence of mechanics matters more, compare with the static ESR-3P-T1F for 6–400 kVA with a range of up to ±50 %. For sites above 600 kVA there is the ESR-3P-T2F/T3F for 450–3125 kVA.

FAQ
Does the SVS-3P regulate each phase separately?
Yes, regulation is independent per phase, so voltage imbalance between phases does not pass to the load.
What is the maximum power of the SVS-3P?
The series ends at 600 kVA, with 27 ratings in total starting from 6 kVA.
Can the SVS-3P be obtained with an isolation transformer?
Yes, most models are available as a power conditioner with an isolation transformer and noise filtering.
What grid deviation can the SVS-3P withstand?
The input voltage may deviate by up to ±40 %, and the output is held with the adjusted accuracy of ±1…±5 %.
For which grid voltages are SVS-3P versions available?
H/HD for 380–415 V, LY/LD for 190–240 V and HX/HXD for 440–480 V.
