Peco PL35 Capacitor Discharge Unit

Peco PL-35 Capacitor Discharge Unit For use with all solenoid type point motors such as Peco PL-10 / PL-11 or Seep PM-1, PM1Buffers, PM-2 or PM-4. Connect to the 16v ac supply on your transformer. The capacitor in the unit stores up power and discharges a 'kick' to ensure turnout blades 'snap over' every time. Connected to turnouts via switches such as PL-26, R044, A280-15 or probe and studs PL-17 / PL18 Will operate one turnout at a time.

CDU is recommended rather than optional. “Back in the day” accessory outputs from controllers were of a higher amperage, but nowadays they are commonly not more than 1 amp. The PL-10 probably needs at least 2 amps. Also, as the PL-10 is a solenoid motor operated by a passing contact switch, any prolonged period of being “on” will burn out the motor, so a CDU also acts a safety device ensuring that this does not happen.
