Power Supplies

The C-Bus Power Supply Unit supplies C-Bus power to passive C-Bus units such as Key Inputs and Occupancy Sensors. For ease of installation the units are DIN rail mounted measuring 4 DIN modules wide. Capable of supplying the power needs of up to 18 standard passive C-Bus units, the Power Supply can source up to 350mA to the C-Bus network.

The unit is fully compatible with the C-Bus Professional Series of high power architectural dimmers and also complements the non-powered range of DIN Rail Relays and Dimmers.

The power supply is a switched mode type specifically designed to operate with the C-Bus system. The advantages of the switched mode design include its smaller volume, higher efficiencies and low power dissipation.

Designed to operate in parallel with other C-Bus Power Supply units, up to 5 DIN Rail Power Supplies may be connected to a single C-Bus Network. Under these  circumstances each power supply unit shares the load equally. To enhance maximum efficiency, the Power Supplies should be distributed equally along the C-Bus Network.

They also feature two status indicators, a C-Bus Network Indicator and a Mains voltage Indicator. The C-Bus Network Indicator reports on the state of the C-Bus voltage level and the presence or otherwise of a system clock. The Mains Voltage Indicator reports on the presence of a mains voltage to the unit.

The unit incorporates short circuit and reverse polarity protection and the line voltage is galvonically isolated from the output.
