SVR-3P Series

Servo Electronic
Voltage Stabilisers & Power Line Conditioners
Three Phase
6 to 120 kVA

SVR Series - Three-Phase
Servo Electronic AC Voltage Stabilizers - 6 to 120kVA

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 (SES) Stabilisers are able to handle the widest of input voltage windows (up to ±40%).

Now Digitally remastered to meet the demands of today’s modern age, our latest generation SVR 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 16 different power ratings from 6 to 120 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).

 – Manual Bypass:Break Before Make’ bypass facility (with mechanical interlocking) offering the ability to route the supply feed to bypass the stabiliser/conditioner. Useful when performing deep maintenance on the system, or in the highly unlikely event of a system malfunction.
 – Output Isolation:Automatic disconnection of the load in the event of a fault condition being detected
 – Phase Failure:Any failure of phases will be immediately detected and will instigate an automatic load isolation
 – Over & Under VoltsAbility to configure the voltage stabiliser/power conditioner, to shut down in the event of the incoming voltage supply going outside the specified input voltage window

 – Maximum Altitude:1000 meters (derate by 2.5% per additional 500 meters)
 – Relative Humidity:Suitable for indoor tropical use – 0 to 95% (non-condensing)
 – Harmonic Distortion:None introduced
 – Audible Noise:@ 1 meter 50 to 65 dBA (dependent on model rating)
Physical:
 – Power Connections:Hardwire Input & Output with bottom cable entry (Option – top and side cable entry)
 – Construction:Enclosures to IP20 / NEMA 1 Style – BS EN 60529  (Option – Outdoor IP54/NEMA 3 Style)
 – Paint Colour:RAL 1013 (Oyster White – Epoxy Powder Coating) – Other paint colours on specific request
 – Dimensions & Weights:Dependent on model rating and configuration
Sizes and weights available on individual request
Certification & Conformance:
 – EMC Conformance:BS EN 55022 and relevant parts of BS EN 61000
 – CE Certification:CE Marked – 2014/30/EU (The EMC Directive) and 2014/35/EU (The Low Voltage Directive)
 – Warranty:2 Years / 24 Months from date of supply
Optional Add-Ons:
 – Outdoor IP54 Enclosure (-IP54)Stabiliser presented in endurable IP54 (BS / EN 60529) / NEMA 3 free-standing steel cubicles suitable for external use, or more challenging internal environments
 – 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
 – Additional Digital Metering (-ADM)Additional Digital Metering for Frequency & Power Factor
 – 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

Note:

1: All SVR Stabilisers are designed to support the full load at minimum input volts and maximum ambient temperature.
2: Where the nominal utility supply is 3 Wire (Without Neutral) in nature, models are also available, on specific quotations, offering a 4 Wire (with Neutral) Output.
