1C. C-Bus Hardware

3.3 Professional Series Dimmer

The Lx510xDx Professional Series Dimmers are C-Bus output units suitable for dimming resistive and

low voltage loads in lighting applications. Each channel is load rated between 5A and 20A (depending

on the unit’s model).

Housed in an all aluminium heat sink, the dimmers have been designed for fast installation, with

features such as keyhole mounting, front and rear cable access, ample termination space for mains

cabling, and removable terminals for C-Bus and override connections. They have independent

dimmable channels, operating from a single-phase mains voltage. They operate with any mains

frequency in the range 47 to 53Hz or 57 to 63 Hz, and will automatically resynchronise when this

frequency varies.

Professional Series Dimmers draw 18mA from the C-Bus network when not connected to the mains

supply. With mains voltage connected the dimmers provide up to 60mA to the C-Bus network.

3.4 DIN Rail Series Dimmer

The DIN Rail Series Dimmers are C-Bus output units suitable for dimming incandescent and low

voltage lighting. They feature eight leading edge, phase controlled dimming channels. Each channel

has a load rating of between 1 and 2A (depending on the unit’s model).

The dimmers are capable of controlling incandescent and low voltage lighting (utilising iron-core and

electronic transformers, compatible with leading edge dimmers).

Two product variants are available. One incorporates a 200mA C-Bus power supply used to source

current to the C-Bus network. The other is an economical model with the same features and

performance, but does not include the power supply.

3.5 DSI Gateway

A DSI Gateway is a DIN rail mounted C-Bus output device, designed for controlling ATCO-Tridonic

DSI dimming ballasts, or an equivalent product that uses the DSI protocol standard.

DSI Gateway units incorporate eight independent control channels, for switching and dimming

ﬂuorescent luminaries. They are designed to control up to 100 DSI dimming ballasts per channel,

allowing up to 800 electronic ballasts to be connected to one DSI Gateway unit.

The DSI Gateway is capable of detecting faulty lamps connected to its terminals (depending on the

ballast used). When this occurs, the DSI Gateway will shut down the channel, and the corresponding

channel LED indicator ﬂashes at a slower rate (approximately four times per second).
