Bộ DIMMER Helvar - 458/UNI8 8 × 6 A Universal Dimmer Module

 8-Channel Universal Dimmer Module (458/UNI8)


 The 458/UNI8 is an eight-channel transistor dimmer module for leading or trailing edge dimming.  It is compatible with all common load types: inductive, capacitive and resistive.

The unit incorporates a number of novel features that provide ‘first-class’ performance when dimming modern LED lamps. This includes both mains dimmable retrofit lamps and LED drivers.  The module’s eight channels can be individually selected as leading or trailing edge, and are rated at 6 A each. The module has a DALI and an SDIM/DMX interface, and therefore can be fully integrated into a standalone DALI, a DIGIDIM, an Imagine router or a DMX system.


 Key Features

  • Module plugs into any 458 mechanical chassis
  • LCD display screen with navigation keys
  • DALI/SDIM/DMX
  • Active bottom load
