Capacitor Discharge Unit Circuit

A capacitor is a device that stores electrical energy in an electric field it is a passive electronic component with two terminals.

Capacitor discharge unit circuit.

Capacitor discharge unit cdu1c cdu2c cdu4c capacitor discharge units of various capacities for all sizes of layout. With dc only one loco can be operated at the same time unless the circuit is divided into isolated blocks as the current in the track controls the loco. Cdi circuit using an scr a few resistors and diodes. The effect of a capacitor is known as capacitance while some capacitance exists between any two electrical conductors in proximity in a circuit a capacitor is a component designed to add capacitance to a circuit the capacitor was originally known as a condenser.

The surge of current can cause other electronics to momentarily loose power and in some cases trigger a false short circuit detector. The solution to these problems is a capacitor discharge unit. Designed to work with point motors from all manufacturers. The mk3 has the added function of the led power indicator.

The input to the cdi unit is derived from two sources of the alternator. Model railway electronics capacitor discharge unit the two systems commonly in use to control a model railway are analogue dc and digital dcc. This alone serves as two functions. Our capacitor discharge unit overcomes all these problems.

The capacitor discharge unit is intended to be used in conjunction with the accessory decoders but can be used anywhere that you have solenoid point motors to provide a high current pulse from a low current power supply. The all new mk3 version. This is the very latest from our capacitor discharge units. Essentially a small circuit that holds a charge while the load is not being driven and then releases the charge in a quick blast when the turnout is.

This current burst is over by the time the switch contacts open. It shows when the discharge unit is powered and ready for use. Capacitor discharge units cdu supply a high current burst to the solenoid. Thus eliminating back emf across the switch contacts.

They store excess electrical energy during power surges and discharge it during power lulls to provide the appliance with a constant even supply of electricity. Capacitors are found in a number of electrical appliances and pieces of electronic equipment. Extream high powered capacitor discharge unit. Should a solenoid be left in circuit by the switch being held for a long period the current flowing through the coil after the initial surge will be less than 0 05a so it will not damage to the coil.
