This is an obsolete controller and recommended to use a DDMC802 or DDMC802GL with relay modules and HF ballast modules to achieve the same product.

The DDBC400 is designed to control 1-10V and DSI high frequency fluorescent ballasts and has the facility to also control dimmed and switched loads. The DDBC400 has two output modules. One is fixed as a 4 channel HF ballast controller that can be configured for 1-10V or DSI operation. The other output module is a plug-in type which can control a variety of loads, simply by selecting an appropriate output module. The plug-in modules also facilitate ease of servicing. The device is DIN rail mountable, designed to be installed in a switchboard, optionally next to circuit breakers feeding the circuits to be controlled. The DDBC400 can operate as a stand-alone unit or as part of an integrated system when connected to a DyNet network. technical data Supply 230V 50/60Hz single phase & neutral at 5A Outputs Module 1: User definable Module 2: 4 x 1-10V and DSI HF ballast control Available output modules: LSDM401 – 4 x 2A leading edge dimmer module, 5A max module load LSRM401 – 4 x 2A relay module, 5A max module load (resistive) relay contacts TV8 rated LSDM105 – 1 x 5A leading edge dimmer module LSFCM202 – 2 x ceiling fan (400VA max per fan) 3 speed control module Power Conditioning (dimmer modules) • Regulated outputs • Over voltage protection • Surge protection • Brownout/Sag protection • Spike protection • Soft start • 16 bit fade resolution (65535 steps) Control Inputs 1 x RS485 DyNet serial port 1 x AUX programmable dry contact input User Controls Service Switch Diagnostic LED Internal Controls 365 day Time Clock Inbuilt Programmable Logic Controller DyNet DC Supply 50mA (supply for approx. 2.5 Smart Panels) Preset Scenes 170 Diagnostic Functions* Circuit run time tracking on each channel Device Online/Offline status * DLight, DTK600 Touch Screen or BAS interface is required for displaying and analysing diagnostic data.
