Q&A
- Q: Can this board replace older 3BHB series versions?
- A: It is typically backward compatible within the same drive family, but firmware revision checks are recommended.
- Q: Why are fiber optics used for this board?
- A: Fiber optics provide total electrical isolation between the control logic and the high-voltage power stage.
- Q: Does this unit include the IGCT semiconductor?
- A: No, this is the driver board; the IGCT power module is sold separately
