KEY BENEFITS

Why it pays for itself

Up to 70%

Reduction in equipment breakdowns

Depending on input voltage variation and plant working hours — resulting in zero breakdown and better utilisation of manpower & equipment.

5–25%

Energy saving

Depending on the input voltage variation and working hours of the plant.

10–15%

Reduction in MDI

A definite reduction in Maximum Demand Indicator follows installation of the equipment.

10–15%

Improvement in power factor

Achievable as the output supply remains stable.

1 Year

Unconditional guarantee

Warranted unconditionally after installation at site, backed by a widespread service network across most states in India with on-site support.

Balanced or unbalanced

Built to your load

Manufactured for unbalanced or balanced load as per customer requirements, at 98.5% efficiency compared with conventional servo stabilizers.
