Servo voltage stabilisers
Servo voltage stabilisers in three-phase and single-phase configurations, wound and assembled at Faridabad.
Correction is continuous, through a variable winding and carbon brush gear, rather than stepped taps. On three-phase units each phase is tracked independently. Single-phase units are also built; their ratings and configuration are engineered to the requirement.
- Continuous correction rather than stepped taps
- Three-phase and single-phase configurations, wound in-house
- Each phase corrected independently on three-phase units

| Phase configurations | Three-phase and single-phase Both are built. The rating range below is the three-phase range; single-phase ratings are set per order because no single-phase range has been recorded yet.Source: Confirmed by the proprietor, 7 Sep 2026 |
|---|---|
| Rating range, three-phase | 30 kVA to 2500 kVA The three-phase range built. Your rating within it is set by the load you are protecting. This figure is NOT a single-phase range and must not be read as one.Source: Superseded catalogue page 12, confirmed by the proprietor 23 Aug 2026 |
| Rating, single-phase | To your requirement Single-phase units are built, but no single-phase rating range is on record. Ratings and configuration are engineered to the requirement — tell us the load and we will confirm what is available. |
| Input voltage window | To your requirement Set by your measured supply variation. |
| Output regulation band | To your requirement Specified against the tolerance your equipment requires. |
| Correction speed | To your requirement Selected against how fast your supply moves. |
| Correction method | Carbon brush gear on a variable winding Source: Existing site copy, carried from Company Profile 2026 |

| Internal construction, photographed unit | Buck-boost winding above, variable winding assembly below, aluminium busbar links Observed in a works photograph of one three-phase unit under assembly, and attributed to it rather than to the range: strip-wound buck-boost coils on a laminated core, the variable winding assemblies beneath, and an insulated terminal board at the base.Source: Master photograph 20250320-170032a.jpg, works, 20 Mar 2025 |
