When the track is in a horizontal position the Power Slider's motor will move the carriage along the rail/track with a maximum load of 5kg, or 12kg if the carriage has hybrid bearings. (This is total weight on the carriage, camera plus head.)
Please note the motor drive is not silent, so the camera's onboard microphone is likely to pick up the sound of the motor, especially at the higher speeds.
Approximate speeds powered at 6v and 12volt. Distance the carriage will travel, per second, when powered at 6 volts - Set at minimum speed 1.6mm. Set at maximum speed 54.6mm. Distance the carriage will travel, per second, when powered at 12 volts - Set at minimum speed 12.6mm. Set at maximum speed 112mm. The speeds are variable from minimum to maximum and the supplied mains adapter can be set at either 6v, 9v or 12volt.
