- **Caution**: 

### Q: What is the primary function of a power distribution module in electrical equipment?
**A**: The power distribution module receives incoming electrical power, conditions it through filtering and protection circuits, and distributes clean, regulated power to various sub-circuits and components within servo drives or actuator systems.

### Q: What materials are typically used in manufacturing power distribution modules?
**A**: Power distribution modules are constructed using Printed Circuit Boards (PCBs) with copper bus bars/traces, electronic components like capacitors and inductors for filtering, fuses or circuit breakers for protection, and housed in durable plastic or metal enclosures.

### Q: How does the protection circuit in a power distribution module work?
**A**: The protection circuit, typically consisting of fuses or circuit breakers in the BOM, monitors current flow and interrupts power in case of overloads, short circuits, or faults to prevent damage to downstream components and ensure system safety.
