Modelling Electronics 102-002 Micro Capacitor discharge Unit MK4 102-002

High power Capacitor Discharge unit. Designed to work with point motors from all manufacturers. The dual MK4 has one capacitor with 4700uf which ensures fast responsive action when switch one point motor 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
