CT2N3 is a microcontroller-based wiper control system for 3 wiper motors.
CT2N3 is composed of one control panel CP4P3 and one relay box SRM3P.
Control panel is connected to relay box by one serial cable (CANBUS cable) with two 8 pole plugs. Every unit has two plugs (in parallel) and any one or both can be used.
Each wiper can be switched on one by one.


  • three intermittent speeds (four in case of single speed motor)
  • one or two continuous speeds
  • synchronized brushes at any mode
  • motor brake
  • washing program
  • an additive control panel CP4P3 can be added to work from different stations

Power supply10V to 30V DC
Internal fuses12A self-resetting fuse for each motor
Stand-by currentLess than 70 mA at 10V and less than 40 mA at 30V
ProtectionsPolarity inversion
Motors- output currentsSingle or double speed – each motor 12 Amps max.
Inputs3 parking switches (open in park position)
Outputs3 SLOW speed Imax = 12A
3 HIGH speed (if using two speed motors) Imax = 12A
1 wash pump (positive pole) SLOW Imax = 1A
Functions3 or 4 intermittent settings
1 or 2 continuous speeds (slow and high speed)
