Interface Board SDCS-SUB-4
General
On SDCS-PIN-4 and SDCS-PIN-51 the line voltage and DC voltage measurement is done by high
ohmic resistors typical 5 M ohm for 500 V units.
Voltages below 100 V line voltage must be adapted by smaller resistance and rescaled measurement
channel. Such rescaling provide improved mains synchronization and DC measurement resolution at
small voltage.
SDCS-SUB-4 board provides a different scaling of voltage measurement. The default selection is 1.17
Mohm with maximum mains voltage of 120 V. The maximum measurement voltage scale is 200 V.
Adjust voltage scaling parameter according to table below.
