Pc-board DK-DCDRV
The pc-board DK-DCDRV is managing the primary drive level of the power unit.
Functions
- encoding power unit
- connection of the thermal sensor (at heat sink)
- supply current sensor
- monitoring bus voltage and supply voltage
- safety shut-down of power unit
- passthrough signal power-up relay
- passthrough output of current sensor
Encoding power unit
The type of the power unit is set via the DIP switch.
