Model Railway MK4 Dual Capacitor Discharge Unit (CDU)

• With the CDU board in the above position and the terminal blocks on the right. The bottom two connections and for you power supply input. Which are marked in AC/DC the top two connections marked - + are the output to your point motors.

Product description High power Capacitor Discharge unit. Designed to work with point motors from all manufacturers. The dual MK4 has two capacitors with virtually 10,000uf which ensures fast responsive action when switch two or more points at any one time. This unit is also useful for larger scales or with points operating some distance from the control board. Provides a high current pulse to "snap" points across positively from the 4700uF capacitor. Limits subsequent points current to prevent coil burn out. Prevents voltage drop to other parts of the installation during points action. Operates on AC or DC. Up to 22v input Wiring The board will accept power between 16V and 22V AC or DC for input voltage Safety Warning Not for use by children under the age of 14
