Power Supply Board SDCS-POW-4
The SDCS-POW-4 board is designed for DCS800 converter modules and is mounted on the electronic
support. This board is used for all types of modules type D5, D6 and D7 (>1000 A and rebuild system
DCS800-R).
The SDCS-POW-4 works on a switched mode basis in fly back configuration. It generates all necessary
DC voltages for the SDCS-CON-4 and all other electronic boards. The input voltage is automatically
detected and set to either 230 V AC or to 115 V AC. The following figure shows the instructions for the
selection of the encoder supply voltage.
Auxiliary supply voltage X99
* Frequently switching ON and OFF increases inrush current
If SDCS-CON-4 input X5: is used for encoder speed measurement, the
incremental encoder supply voltage for 5V, 12 V or 15 V must be selected
by jumpers S3, S4 and S5.

These two terminals are used to add addi-
tional capacitance to the existing ones to
increase the mains buffering time. More

encoder supply
The 24 V encoder supply can be selected either directly from
CON-4 board (S4=11-12) or from POW-4 board (S4=10-11);
S4 is located on the CON-4 board
