ESR Series

Single-Phase Static Electronic
AC Voltage Stabilisers / Power Conditioners
3 to 100 kVA

ESR Series - Single Phase
Static Electronic AC Voltage Stabilizers - 3 to 100kVA

Ideal for general commercial and industrial applications, ESR Static Electronic Single-Phase Voltage Stabilisers not only guard against voltage fluctuations they also offer protection against all too common harmful high-energy surges, transients and voltage spikes.

Offered as two ranges, in ratings from 3 to 100 kVA, H Series models support international 220 to 240 Volt utility mains supplies and L Series models support US-Style utility supplies of 110 to 127 volts.

As a virtually maintenance-free solution,  models are also available in IP54 / NEMA 3 Style Enclosures (-IP54 Option) and as Power Line Conditioners (-PC Option).
