CDU4F Fast Charging Capacitor Discharge Unit with Ready LED

The CDU4F Fast Charging Capacitor Discharge Unit delivers a powerful, short-duration current pulse to ensure positive and reliable point motor operation. By storing energy in internal capacitors and releasing it in a controlled burst, it provides strong switching performance without placing excessive load on your power supply. After the initial surge, the CDU limits sustained current to protect point motors from burn-out caused by wiring faults or prolonged switch operation. It also prevents voltage drop across the rest of the layout while points are being operated. Key Features Delivers a high current pulse for positive point motor operation Protects point motors from burn-out caused by wiring faults or prolonged switching Prevents voltage fluctuations across the layout during operation Fast charging for rapid recovery between operations Built-in LED indicators for charge status monitoring Ready light fitted as standard, with additional control panel ready LED connection for remote indication. Available in storage capacities suitable for layouts of all sizes Power Requirements Up to 35V DC or 24V AC input Commonly used with 16V AC controller auxiliary outputs Minimum recommended supply: 12V AC or 15V DC Documentation & Support For detailed information on installation, wiring connections, and troubleshooting, please download the latest instruction manual: Product Instruction Manual
