APPENDIX A – DC POWER SUPPLY DESIGN
A.1 Design
This section has additional considerations for DC power supplies.
A.1.1
Single Power Supply Operation
A single power supply can be used to provide main or motor power and control power for the
DC power input. The voltage range of a single supply is 20 V to 90 V.
NOTE
The drive can be damaged if the supply voltage exceeds 90 V, even
briefly. The DC level plus transients plus regenerative pump up MUST
NEVER exceed 90 V.
Wire the single terminal to J1-3 (+Bus) and to J1-1 (+CTRL) and the power supply –
terminal to J1-2 (Bus/Ctrl Gnd). This power supply is typically unregulated, but a regulated
supply can also be used. The power supply outputs must be isolated from the power line. See
Regulatory Information for more details on isolation requirements. Wire both the power supply
negative terminal and the drive chassis to earth for safety.
The maximum continuous and peak (3 sec) main power and current at 75 V bus for the S200
DC drives is shown in the table below.
