Speed controller
1Q transistor speed controller type GS 24S/xx-360
Product information
1Q transistor speed controller type GS 24S/xx-360
The GS 24 S/xx-360 Series transistor speed controllers are low-cost compact devices measuring 72 x 100 mm for stepless speed control of any brushed DC motors in the low-voltage range up to max. 10 A motor current. The input voltage range is 20 to 36 V DC, making battery operation possible, e.g. from an on-board electrical supply system or through SNT 24/xx Series mains adapters connected upstream. Stepless speed control can be realized either via an internal/external potentiometer or an external reference voltage 0….10 V DC. An internal potentiometer acts as an overload protection by providing a continuously variable motor current limitation.
Features
- Input voltage 12 – 36 V DC
- Up to 10 A motor current
- Stepless speed adjustment
- High pulse frequency of 18 kHz allows for a quiet operation
- Form factor F < 1.05 guarantees reduced motor heating and high MD reserves
- Adjustable rotation speed via 0 to 10 V interface or potentiometer (external or internal)
- Enable-input for output stage activation
- Overload protection of motor or drive through stepless current limitation
- Short-circuit-proof output stage (option)
Accessories
- Module carrier for 35 mm mounting rail installation
- Short-circuit-proof output stage
- Suppressor diodes for automotive applications with high induction peaks
- Ref. value potentiometer 1 gear or 10 gears
- Switch-mode power supply: SNT 24/xx Series; input voltage 115/230 V / AC 50/60 Hz
The additional circuit board 393 provides the facility to change the direction of rotation of a permanent magnet motor with a transistor chopper controller type GS 24 S/xx-360 under low voltage of 12 to 48V DV and a nominal current of max. 10 A. The direction of rotation, clockwise or counterclockwise, can be pre-selected during standstill via a 12 V to 48 V DC control signal.
