Speed controller
4Q transistor speed controller type DLRB 24/xx-496
Product information
4Q transistor speed controller type DLRB 24/xx-496
The DLRB 24/xx-496 Series transistor speed controllers are load-independent 4-Q motor speed controllers for brushed DC motors with integrated ballast unit. These controllers enable stepless speed control in clockwise and counterclockwise rotation up to a maximum motor current of 10A. The input voltage range is 10 – 48V DC. Stepless speed control can be realized either via an internal or external potentiometer or an external reference voltage of 0 – 5V DC or 0 – 10V DC. The motor power can be steplessly limited using an internal potentiometer as overload protection.
Features
- High pulse frequency of approx. 23 kHz allows for a quiet operation
- Speed specification via 0 – 5V DC or 0 – 10V DC interface or potentiometer (external/internal)
- Controller enable – input for activating the output stage (one input per direction)
- Motor overload protection through internally adjustable current limitation
- Acceleration/deceleration ramps adjustable via internal DIP switch, blocking protection can be activated via internal DIP switch
- Controller/setpoint releases can be inverted via internal DIP switch
- 8-bit processor
- Speed control range 1:30 with EMF and I×R compensation, 1:500 with encoder
- EMK feedback system with I×R compensation (or encoder)
Technical features
- Input voltage 10 – 48V DC
- Up to 10A motor current
- With ballast unit for protection against generic energy
Accessories
- Sheet metal cover
- Snap mechanism for 35 mm mounting rail
- Ref. value potentiometer 1 gear or 10 gears
- Switch-mode power supply: SNT24/xx Series; Input voltage 115/230V / AC 50/60Hz
