3 Channel Professional Dimmers
The 3 channel Professional Dimmers designed for commercial applications such as hotels, restaurants
and oce buildings.
The dimmers are C-Bus controlled, high power, multi phase control units, compatible with a wide range
of load types, including neon. Dimming is achieved through phase control techniques creating a highly
ecient range of dimmers.
The Professional Dimmers provide on-board MCB protection and thermal overload protection, and
contain modular output channel cards of various ratings, allowing customisation to suit site needs.
A maintained active output is provided on each channel for emergency lighting. Each channel card
has a bypass switch which permits direct local override of the lighting circuit. In the event of an over-
temperature condition, such as one caused by excessive load current, the dimmer channel reduces the
output power.
The Professional Dimmer is designed and tested for a wide range of international markets with
comprehensive EMC and electrical safety testing and is fully ROHS compliant.
PRODUCT FEATURES
• Soft start load turn-on protects lamp laments.
• Voltage compensation to minimise load brightness variation if the AC
supply voltage drifts.
• Filtering reduces supply voltage signalling eects.
• Linear output load power following input control.
• C-Bus network burden and system clock generator.
• After mains fail, dimmers return to previous or preset values.
• Local C-Bus override switches on front panel.
• Channel Status indicators on front control panel.
• On-board MCB and optional RCD protection.
• Mounting brackets included for ease of installation.
• Generous load and mains supply terminals.
• Emergency lighting output for each channel.
• Manual dimmer bypass switch on all channels.
• Fan-free operation, reduces maintenance requirements.
• Suitable for single or three phase track lighting applications with
optional three phase MCBs and RCDs
• CE (European Community) compliant
