Measurement board SDCS-PIN-51
This board is always required with the rebuild kit.
One SDCS-PIN-51 board per kit.
The SDCS-PIN-51 board contains following functions:
- Connection to pulse transformer board / boards
- Interface for heat sink temperature measurement with a PTC resistor
- Measurement and scaling of AC and DC voltage via high ohmic resistors
- Measurement of the armature current and scaling with burden resistors to 1.5 V
for rated current; burden resistors for zero current detection
