OUTPUT UNITS |
8 Channel Dimmer Range
Learn Enabled
The 8 channel dimmer units are DIN rail mounted units employing leading edge phase control circuitry for dimming control.
These dimmer units feature learn mode, local and remote overrides for on/o control, channel, C-Bus and unit status
indicators.
Each dimmer channel is rated at 1 Amp and is suitable for incandescent and low voltage lighting using magnetic and
leading edge compatible transformers. The dimmer output is controllable over the range of 2-98%, while frequency
tracking algorithms ensure icker-free operation and smooth dimming control.
The dimmer units are available as passive and current sourcing models that source up to 200mA to the C-Bus network.
