CDU2C-FC Fast Charge Capacitor Discharge Unit

About the Product

The BLOCKsignalling CDU2C-FC is a fast charging capacitor discharge unit designed for reliable and safe operation of points motors on medium to large model railway layouts.

It stores electrical energy in internal capacitors and releases it as a short, high current pulse when a switch is operated, ensuring strong and consistent point switching while protecting both motors and control switches.

This provides a sharp, positive movement of the points without allowing sustained current through the switch contacts, helping to prevent overheating and electrical arcing.

The fast charging design allows the unit to recharge in a fraction of a second, making it ideal for layouts where multiple points may be operated in quick succession.

Key Features

• Provides a high current pulse for reliable points motor operation.
• Protects points motors from burn-out by limiting sustained current.
• Prevents switch contact damage by eliminating electrical arcing.
• Reduces voltage fluctuations across the rest of the layout.
• Fast charging for rapid recovery between operations.
  
• Built-in indicator LEDs.
• Suitable for operating multiple points, even over longer distances.

Electrical Requirements

• Accepts 12V AC to 24V AC or 15V DC to 35V DC input.
• Recommended supply rating: 1A.
• Compatible with controller auxiliary outputs or suitable DC power supplies.
