Capacitor Discharge Unit

For operating heavy duty point motors
The unit stores up power in capacitors and when a point motor is actuated, discharges in one big punch giving the point motor a firm and positive switching action. Connected to points via switches or probe and studs. Prevents burnt out motors.
Input:
16v to 24v A.C. at a maximum of 2.5 amps (Gaugemaster T3 recommended).
