Series Brushless Controllers
BDP-Q2-50-10 , BDP-Q2-20-10
2-quadrant speed controller for brushless motors
Instruction Manual
GENERAL
• The BDP-Q2-50-10, BDP-Q2-20-10 controllers are 2-quadrant speed controllers for electronically
commutating three-phase brushless motors with Hall sensors, which are arranged offset at 120
electrical degrees.
• The speed of the motor is preset by means of either an internal or an external potentiometer.
• The maximum constant current can be adjusted via an on-board potentiometer.
• The Direction of rotation of the motor can be preset by means of the Direction control input.
The controller output stage can be activated and deactivated by means of the Disable control input.
• The controller is safeguarded against heat overload by means of an internal thermal cutoff.
• The controller output stage has been constructed using POWER-MOSFET technology, resulting in very
highefciency.

ASSEMBLY NOTE
Optimum heat dissipation is achieved by mounting the BDP-Q2-50-10, BDP-Q2-20-10 controller on a heat sink, and
through the use of a thermal conduction paste.
For longer distances between the motor and the control unit, > 12 in (30 cm), shielded cables should be used for the
sensor cable and the motor cable.
SAFETY NOTE
Operatingvoltagesexceedingthespeciedvalues,orreverseconnectionwilldestroythecontrollerandwillvoidthe
product warranty.
Unauthorized opening and improper repairs will put the user in danger and will void the product warranty.
If the controller is brought from a cold environment into the operating environment, there can be condensation. Wait
until the controller has reached the ambient temperature of the operating environment, and is absolutely dry before it
is put into operation.
