4. GETTING STARTED
Connecting a motor:
The motor is connected by using the two clips with + and –.
Connecting the power supply:
The power supply is connected to the two outer clips with the markings + UB and
– UB. Make sure that the connection is done in the correct polarity. Connecting
with the incorrect polarity can destroy the device.
Adjusting the pulse width:
The potentiometer P1 will adjust the pulse width of the power output. This
correlates directly with the speed of the motor.
In case of a short-circuit:
The adjustment of the power output is dependent on the connected motor and
use controlled with the potentiometer P2. (Left = low output). Turning the controller
to the very right results in maximum output. In the case of short-circuit disconnect
the controller immediately from the power supply, repair the short-circuit and
reconnect the power supply. Please note that a continuous short-circuit could
damage or destroy the controller.
– The accident prevention regulations of the professional associations for
electrical systems and equipment should be strictly followed when installing
this device in commercial buildings.
– In schools, training centers, clubs and workshops, the operation of modules
and devices must be monitored by trained personnel.
– If the device should be serviced repaired, only original spare parts may
be used. The use of incorrect spare parts can cause serious damage and
personal injury!
– If it is not clear which characteristics apply for a component or a module, how
to install the controller or what external components or additional devices may
be connected, please consult an expert and specialist. Make sure that all
connected devices and modules are suitable for the device and application.
Please note that operating and connection errors are beyond our control. No
liability will be taken from damages resulting from connection and operating
errors.
3. PRODUCT DESCRIPTION AND SPECIFICATIONS
This universal pulse width controller allows the step less control of the speed of
DC motors without barely any loss. By using pulse width control (0 to 100%)
the loss is extremely small even at low resolutions. An integrated short-circuit
protection prevents that the device is destroyed. This device was designed, built
and tested according to EMVG (EG directive 9/336/EWG/Electromagnetic
Compatibility) and was awarded with a CE certificate.
Changes of any kind may not be made to the PCB. This will violate the CE
approval.
