Compact made by Trietex® for the comfortable operation of vertical blinds motorized by a 24 V DC motor. The motor is available with two different gears, the standard gear and the reinforced gear for heavy duty, which runs at half the speed of the standard gear. The motor is available for mounting on the right as well as the left end of the rail. Independent of which side the motor was mounted, the tilting direction of the slats and the position of the stack can be adjusted and inverted by dip-switches. The end positions can be easily adjusted with two buttons on the lower side of the motor. An integrated current protector preserves the motor against mechanical or thermal overload. No time-lag of the blinds if the motor is switched off or in case of power failure by a self inhibiting Wolfrom gear.
