ESDONI SN

Product catalog summary

Product Overview

The ESDONI SN series are three-phase light flux stabilisers and dimmers designed for voltage regulation without a neutral wire. They are intended primarily for outdoor lighting installations using high-pressure sodium vapor (HPS), mercury vapor (MV), or metal halide (MH) lamps. The devices stabilize line voltage with ±1% precision under load variations from 0% to 100%, ensuring energy savings and improved lamp performance.

Key Features

Voltage regulation with ±1% precision for input voltages of 230 V ±7%.
High efficiency exceeding 99% at rated load and above 98% at reduced load.
Stepwise output voltage variation.
Independent phase protection for each phase.
Class I electrical shock protection via grounding terminal.
Natural ventilation without forced cooling, enabling easy maintenance.
True RMS measurement of output voltage.
No harmonics, micro-cuts, or power factor variation introduced.
Installation at the line head without requiring modifications or control wiring.
Available in metallic (RAL-7035, IP54, IK10) and polyester (RAL-7035, IP44, IK10) cabinets, as well as assembly board versions with metallic covers (RAL-1003, IP20).
