The MTC Power Board is an expansion board for the universal MIDI control electronics MTC64. It is used to switch mains voltages (230V/115V) to drive mains voltage devices. For example lamps or other mains loads can be controlled by MIDI note on/off messages.
These are the most important features:
16 power outputs 115V or 230V
max. 2A for each output (i.e. 460 Watt/VA @ 230V resp. 230Watt/VA @ 115V)
max. total load for all outputs 16 A, i.e. 1A for each ouput in case of equal loads for all outputs (= 115 Watt/VA @ 115V resp. 230Watt/VA @ 230V)
zero crossing switches to reduce mains interferences
separate fuse for each output
mains and load connections via screw terminals
up to four MTC power boards can be connected to one MTC64 main board
connection between MTC power boards and MTC64 main board via one 10 pin ribbon cable leading from the main board to all power boards, and a 16 pin ribbon cable between main board and power board (one for each power board). Please specify how many power boards have to be connected to the main board (because of the lenght and number of female connectors of the 10 pin ribbon cable)
ribbon cables are included with the power board, cables for mains and loads connection are not included
On the main board the integrated circuits labelled CD4094 have to be replaced by 74HC4094 (valid only if an already existing older main board manufactured before 2005 is used, in case of new orders of main boards in combination with power boards the main boards are already equipped with 74HC4094)
Installation and wiring of the MTC power board has to be carried out by qualified personnel only because of electrical safety (dangerous mains voltage 115V / 230V). Not qualified personell is not allowed to install and run the MTC power board ! DANGER TO LIFE ! The user has to read the installation manual carefully and follow all instructions in the manual meticulously ! The complete construction has to be mounted into an isolating case before the mains voltage is applied.
