Abstract: A window covering system includes a window covering, a motor having a housing and a power supply inlet, for opening or closing the window coverings, and a modular motor converter. The modular motor converter includes a low voltage interface for functional attachment to the motor, a housing for the low voltage interface, a standard motor power supply connector incorporated into the housing and fitting into the motor power supply inlet, and at least one attachment arm, preferably two, that clips onto the motor housing and permits quick clip-on and removal from the motor. In one form, the modular motor converter further includes a remote radio frequency control for functional attachment to and control of the motor. The modular motor converter also includes means for pre-setting silent stop of the motor end positions. The housing permits external access to motor dip switches.
