SVS Series - Three-Phase
Servo Electronic AC Voltage Stabilizers
6 to 600kVA
With over 30 years of unrivalled experience, gained in some of the world’s most challenging and demanding power environments, our long-standing Servo Electronic Stabilisers are able to handle the widest of input voltage windows (up to ±40%).
Now remastered to meet the demands of today’s modern age, our latest generation SVS Series three-phase offerings include as standard many advanced protection features – usually only available from others as additional expensive add-on options!
For less prevalent situations, where electrical noise is also an issue on-site, most models are also available as Power Line Conditioners offering an enhanced level of Transient Voltage Surge & Spike Suppression (TVSS) protection and delivering the added benefit of filtering out any electrical noise and interference present on the incoming utility supply – ensuring what is commonly referred to as a ‘CLEAN’ supply
Three Phase 4 Wire and 3 Wire (without neutral) models are offered in 27 different power ratings from 6 to 600 kVA, being able to accommodate situations where the incoming nominal utility supply is either 380 to 415V (H/HD Series), 190 to 240V (LY/LD Series), or 440 to 480V (HX/HXD Series).

![]() | Full Manual Maintenance Bypass (-MBS) While many Customers, following traditional wisdom, prefer to install a bypass facility that is external to the Stabilizer/Conditioner, where requested models can be fitted with an integrated traditional ‘Break Before Make’ bypass facility. This feature is handy when performing remedial works or deep maintenance on the system. |
![]() | Input Isolating Transformer (-PC) Through the integration of a shielded isolation transformer, provides enhanced spike & electrical noise (Common Mode: 120db @ 100khz & Normal Mode Noise: 60db @ 100khz) suppression and neutral ground bonding. Delivers what is commonly referred to as a ‘CLEAN’ supply |
![]() | AquaStop (-AS) PCB protective coating offering protection against damp and moisture ingress |
![]() | Digital Power Metering (-DPM) Microprocessor based output digital power metering, with the option of event logging – monitoring V, A, W, VAR, PF, W Hrs & VAR Hrs and the offering RS-485, Modbus RTU, Modbus ASCII, Jbus Protocol interface |
![]() | Digital Power Metering (-DPM2) Additional Input & Output Digital Metering with RS-485 Interface |
![]() | 4 Pole Switches / Breakers (-FP) As standard ESR Stabilisers utilise 3 Pole Switches / Breakers. As an option 4 Pole alternatives can be supplied. |
![]() | Alternative Paint Colour (-RAL) Alternative Paint Colour Finish – customer to specify |
![]() | Output Circuit Breaker (-OCB) Replacement of the Output Contactor with an Output Circuit Breaker |
![]() | UL Recognised Component (-URC) For applications where UL compliance is required, the Stabilizer / Conditioner can be supplied with UL approved Input Breakers and Output Contactors / Breakers, so that the client can obtain on site UL approval of the installation |
