2. General information
The digital, load-independent 4-Q motor speed controllers of the DLR 24 /xx-466
series are cost-effective compact devices with the dimensions of 140 x 125 x 52 mm
for stepless speed control for any type of brushed DC motors in the low voltage
range up to a maximum of 10 A motor power. The input voltage range is from 10 to
36V DC, this allows direct battery or on-board power supply. A DC power supply of
the SNT 24/xx series can also be used. Stepless speed control can be realized either
via an internal/external potentiometer or an external reference voltage 0 to 5V DC or
0 to 10V DC (via jumper 1 and 2 pre-selectable). The motor power can be steplessly
limited using an internal potentiometer as overload protection. Customer-specific
programming is possible as special function.
2.1. Technical features
• Power supply 10V DC – 36V DC (with inverse-polarity protection)
• High clock rate f>20 kHz, this results in low-noise operation
• electric connection via spring clamp terminals
• high level of effectiveness by using Power mosfets
• Mounting: mounted with screws or on a 35 mm mounting rail
2.2. Accessories
• Suppressor diodes via supply voltage (e.g. at automotive applications) for high
inductions peaks
• Ref. value potentiometer: 1 gear or 10 gears. (10kOhm)
