Modelling Electronics 102-003 Dual Capacitor Discharge Unit Mk 4 02-003
High power Capacitor Discharge unit. Designed to work with point motors from all manufacturers. This is the very latest from our Capacitor discharge units. The all new MK3 version. The MK4 has the added function of the LED power indicator. This alone serves as two functions. It shows when the discharge unit is powered and ready for use. The extra added function that the MK4 LED has is when the unit is switched off all other capacitor discharge units store power, if your model railway layout is kept in an out building or shed the power left in the units mixed with the damp can damage the units. The MK4 power LED will dissipate any reaming charge left in the unit within a few seconds making sure your unit is powered down and drained.
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 Please note that PCB Pillars / Standoffs will be required for the circuit board. These fit into the 4 pre drilled holes of the circuit board
