Safe, heavy-duty power distribution for multiple grow lights Our MDF Contactor Boards give you a ready-built, professional-grade way to run several HID ballasts and fans from a single supply. Built around top-quality components and a genuine 24hr Grasslin timer, they're for growers running more than a light or two who want their switching done properly rather than daisy-chaining extension leads. Available in 12/14-socket, 16/18-socket and 24/28-socket configurations. Key Benefits Three board sizes — 12/14-socket, 16/18-socket and 24/28-socket — to match your number of lights and fans Quality 24hr Grasslin timer switches all but the constant-power sockets on a reliable schedule Constant-power sockets for fans and other kit that must run continuously — two on the 12- and 16-way boards, four on the 24-way 40A contactor on the 14-socket board, doubled to an 80A double contactor on the 18-socket board 120A-rated connector block, overrated and capable of handling up to sixteen 600W lights Contactor takes the load off the timer, ensuring safe, reliable activation of your ballasts Fixing overloaded leads and unreliable timer switching Running multiple HID ballasts off a standard timer or extension lead pushes current through components never rated for it — a common cause of timer failure and a genuine fire risk. These boards pass the load through a properly rated contactor and 120A connector block, so your lighting switches reliably and safely however many lights you run. How to Use Choose the 12/14-socket, 16/18-socket or 24/28-socket board for your number of lights and fans Set your light schedule on the Grasslin timer Plug ballasts into the timed sockets and fans into the constant-power sockets All contactor boards must be installed by a qualified electrician Technical Specifications 12/14-Way board: single 40A contactor, 120A connector block, 24hr Grasslin timer, 12 timed sockets + 2 constant-power sockets 16/18-Way board: 80A double contactor, 120A connector block, 24hr Grasslin timer, 16 timed sockets + 2 constant-power sockets 24/28-Way board: 24hr Grasslin timer, 24 timed sockets + 4 constant-power sockets Connector block rating: 120A (handles up to sixteen 600W lights) 16-Way MDF board size: 600 x 300 mm Installation: by a qualified electrician only
