    Auxiliary power distribution

    The electronic power supply board SDCS-POW-1

    (see separate chapter) generates different levels of

    voltages. Some of them are transferred via the

    CON-2 board directly to the boards, where they are

    used, others are manipulated and then transfered.The electronic power supply system with the different

    voltage levels is monitored in two ways. There is a

    signal powerfail primary, which monitors the input

    power supply voltage of the POW-1 board and a

    signal powerfail secondary, which monitors the low

    voltage levels. If one voltage level drops below the

    threshold a trip signal is generated.In addition to that there is a monitoring function for the

    5 V level. If +5 V drops under the tripping level, it

    causes a master reset by hardware. All I/O registers

    are forced to 0 and the firing pulses are suppressed.RS485 serial communication channels

    The control board has two RS485 channels. The first

    channel is for field exciter control of DCF 501/502,

    DCF 503/504 or DCF 601/602 (terminals X16:1...3)

    and the second for the control panel (CDP) at terminals X33 or X34. The terminals X33 and X34 are wired

    up in parallel internally.

    DDCS Channel integrated

    The control board SDCS-CON-2 has an integrated

    DDCS (Digital Drive Control System) channel with a

    tranfer rate up to 4 Mbits/s. This channel (V260) e.g.

    can be used for fieldbus modules. The terminals

    X16:4 and 5 are provided for power supply of the

    modules.The SDCS-POW-1 board is designed for DCS 500

    converter modules and is mounted on the electronic support. This board is used for all types of

    modules independant from current or voltage

    range.

    The SDCS-POW-1 works on a switched mode basis in fly back configuration. It generates all necessary DC voltages for the SDCS-CON-1 and all

    other electronic boards. The input voltage can be

    selected via the switch SW1 either to 230 V AC or

    to 115 V AC. The following figure shows the instructions for the selection of the AC input voltage

    and for the selection of the encoder supply voltage.

    If an SDCS-CON-1 with SDCS-IOB-1 board, or an

    SDCS-CON-2 (without I/O board IOB-3) together

    with a pulse encoder is used for speed measurement, the incremental encoder supply voltage must

    be selected by jumpers X5, X4 and X3.These two terminals are used to add additional capacitance to the existing ones to increase the

    mains buffering time. More detailed data is available on request via your ABB representative.The power interface board is used for converter

    modules model C1. There are 2 different versions

    in use. The used types are:

    - SDCS-PIN-11 for 25 A, 50 A and 75 A converters

    at 500V

    - SDCS PIN-12 for 50 A converters at 600 V

    The SDCS-PIN-1x boards consists of:

    - firing pulse circuits and pulse transformers

    - measurement of the armature current via current

    transformers

    - snubber circuit for thyristors protection

    (consists of RC circuits and MOV elements)
