User manual
motor speeD regulator 12/24VDC 5A
Art.- No. 11 91 525
this speeD coNtrol was specially DesigNeD for low Voltage
electric motors. The main use is infinitely variable rate control of electric DC motors,
model cars, windscreen wiper motors as well as electric tools. Due to the pulse width modu-
lation of 20 Hz, the power dissipation stays low. By using a MOSFET transistor the outgoing
power can be set between 0 A and 5 A. The electronics of the device are protected, even if
the motor should stop unexpectedly. By using a second, additional potentiometer, you have
the possibility of stabilizing the revs per minute, independent of the load connected. The com-
bination guarantees a constant performance of the connected motor, even if the load varies.
HIGHLIGHTS
– High modulation frequency
(approx. 20 kHz), low noise.
– High efficiency by using a
power MOSFET.
– Power output can be adjusted.
– Adjustable “R x I” – compensation
(load compensation)
– Electronic short-circuit and
overload protection.
– Panel mount.

– This device has been designed for indoor use only. Make sure that the alarm unit is not
subjected to high humidity or water.
– If the device has been subjected to colder temperatures and is taken into a warm surrounding,
then first let it adapt to the surrounding temperature, so that condensation cannot cause
damage.
– Make sure that there are no inflammable liquids, gases or dust sources in the near vicinity of
the device during use.
– This device is not a toy and should not be handled by infants and children under 14.
– This device should only be operated by an expert or a person who is qualified to do so.
– When installed in public buildings all rules and regulations referring to public installation
need to be followed.
– If a device needs to be repaired at any time, it may only be repaired with original compo-
nents. The use of different components can lead to serious damages and has a danger of
electrocution.
– If you have doubts on the function or questions, please contact your local dealer or our
service center.
– No liabilities will be taken for damages or claims resulting out of not reading and/or not
following the user guide and/or any form of modification on or in the product. Under these
circumstances, no warranty services will be given.
– Liability cannot be taken for consequential damages.
3. DirectioNs oN the coNtrol carD pcB
These are directions for the use of the Control Card PCB
with electric motors and drive systems according to the
current EG Machinery Directive, EMV Directive and Low
Voltage Directory.
The PCB may only be installed and operated by an expert
or a person who is qualified to do so. All VDE-Regulations
must be followed accordingly. The Control Card PCB
cannot be used as a stand-alone unit. CE marking is only
required for fully assembled, fully functioning devices.
The Control Card PCB or and electronic motor are only
components of a complete system and do not therefore
fall under the rule of individual CE approval.
This controller is designed for controlling the DC power
output and can be used to control the speed of connected
electric motors or the brightness of low voltage lamps.
The user is obliged that the device and the connected
devices are assembled and mounted according to be
applicable regulations.
4. poteNtiometer aND fuNctioN
R6 „I LIM“: adjusts the power output between 0.2 A-5 A.
R7 „PWM“: “PWM”: adjusts the revs per minute of the connected motor from 0% to 100%.
R8 „RxI“: adjusts the “RxI”-compensation. The trimmer is adjusted in such a way that the speed
deviation is adjusted to minimum at the lowest possible speed. Should the speed vary, then the “RxI”
needs to be turned to the left.
5. iNstallatioN
An external power supply is needed. The device may only be installed and operated by an expert
or a person who is qualified to do so. All VDE-Regulations must be followed accordingly.
Operating the controller
1. The power supply required needs a DC voltage of 10–28 V. The fluctuation should be less than
20% at maximum load. The connecting wires to „Netzteil – Gerät“ and „Gerät – Motor“ should
be kept as short as possible and have a sufficient thickness. An external fuse is recommended,
as a reverse voltage will damage the device.
2. The controller can only be fixed to the front blend by using the nut attached to the potentiometer.
Do this, the hole 10 mm is required. If the controller is mounted in a device subjected to
vibration, the controller should be fixed with two additional 3 mm screws.
3. The potentiometer R6 should first be set to full left (0). The adjustment should be done in the
following steps:
a) Turn the potentiometer R8 to the full left. RxI compensation is switched off.
b) Turn the potentiometer R6 to the position required for use.
c) Set the potentiometer R7 to 30–50%.
d) Begin adding RxI compensation by turning the potentiometer R8 to the right and at the same time
adding the load to the electric motor. If the motor starts stuttering or running at different speeds,
then lessen the RxI compensation until the motor is running stable again, by turning to the left.
6. Trouble Shooting
Only use the device if it is functioning without disturbance. If there is any malfunction, switch off the
device immediately and consult a specialist. The device may only be reinstalled after it has been
checked thoroughly. Signs of malfunction are if:
– The device is visibly damaged.
– The device is malfunctioning.
– Attached cables or the housing has come loose.
Repairs may only be done by a qualified person or a specialist using original components and
parts. There is the danger of electrocution.
