SVR Series

Servo Electronic
Voltage Stabilisers & Power Line Conditioners
Single Phase
6 to 50 kVA

SVR Series - Single-Phase
Servo Electronic AC Voltage Stabilizers - 6 to 50kVA

Suitable for 95% of all applications, SVR Servo Electronic (SES) stabilisers not only guard against voltage fluctuations they also offer protection against all too common harmful high-energy surges, transients and voltage spikes.

Digitally remastered to meet the demands of today’s modern age, our latest generation SVR Series models deliver a step less automated regulation of the incoming utility mains supply.

Offered as two ranges, in ratings from 6 to over 50kVA, H Series models support international 220 to 240 Volt mains supplies and L Series models support US-Style utility supplies of 100 to 127 volts.
