ESR-3P-T1F Series

Three-Phase Static Electronic
AC Voltage Stabilisers / Power Conditioners
6 to 400 kVA

ESR Series - Three Phase
Static Electronic AC Voltage Stabilizers - 6 to 400kVA

ESR Static Electronic Voltage Stabilisers work automatically to regulate and protect the load from the vagaries of the utility mains supply.

Being specifically designed to meet the requirements of today’s modern loads, ESR Voltage Stabilisers are configured for optimal energy efficiency and design life expectancy. While output voltage accuracy is set by default to ±3%, this is easily site-adjustable to deliver a more or less precise output voltage accuracy – as considered most appropriate for a particular site’s needs.

As feature-rich solutions, they offer as standard lightning surge suppression, input, and output isolation together with a manual and automatic bypass facility.

The Stabilisers can be supplied configured for either a Three Phase 4 Wire (With a Neutral) or 3 Wire (Without a Neutral) input supply.

ESR-3P-T1F models are available in 24 different power ratings from 6 to 400 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 600V (HX/HXD Series).

Where required, the Stabilisers can be provided as enhanced Power Conditioning solutions with the inclusion of an Isolation Transformer and in IP54 / NEMA 3 Style enclosures for outdoor or more challenging internal environments.

ESR-3P T2F & T3F models are also available in higher power ratings from 450 to 3125kVA>
