4 Channel Dimmer
HES99300
The Helvar Electrosonic HES99300 is a four channel
dimmer unit having a total current capacityof 10A. The
dimmer can control the following load types: incandescent
lamps, low voltage halogen lamps with dimmable
conventional and electronic transformers, 26 mm
fluorescent tubes or compact fluorescent tubes with Helvar
EL-FD electronic ballasts, and 3 wire dimming ballasts for
fluorescent tubes.
The dimmer can be controlled with the Ambience Master
Panels or from a Helvar Electrosonic Imagine system, or
from 0-10V analogue rotary controls or sliders. Remote
panels including one infra-red remote control can be
connected to the Master Panel.
Easy light level adjustment of the four channels is done
directly from the Master Panels. The minimum level and the
fade time adjustment of the dimmer is carried out at the
panel.
