KS250 is a mid-range DC motor driver developed for 12/24V DC motors, with a capacity of 15A continuous / 45A peak and a built-in AntiSwitch safety system. It eliminates the need for external limit switches, simplifying installation and reducing mechanical complexity.
Thanks to adjustable speed control, ramp profiles (soft start/stop) and advanced active braking, it delivers smooth, controlled motion regardless of load. With its IP45 body and analog and digital sensor inputs, it is a mid-range solution that's ready for field applications.
› Built-in AntiSwitch — say goodbye to limit switches. Detects motion limits automatically by current sensing; eliminate cable clutter and manual adjustment errors.

IN1–IN4 direction and stop, IN5 analog — flexible signal management for different scenarios.
✓ Sensor compatibility
Analog and digital sensor inputs for use with encoders, hall, photo and limit sensors.
✓ Compact and efficient
110 g weight, 120 mm long panel-friendly body. Low power consumption with high thermal headroom.
How Does It Work?
1
Connect
Wire the 12/24V supply, DC motor and IN1–IN5 control lines to the terminal block.
2
Speed & ramp
Use the trim pot to set speed and soft start/stop times to your needs.
3
AntiSwitch threshold
Set the current limit for each direction; the system stops automatically at the limit.
4
Commission
Run with manual or RF remote control; the IP45 body is field-ready.
