The new SMD inverter is designed for simple speed control of 3-phase AC motors operating in the power range 0.25kW to 2.2kW, and has an integrated RFI filter meeting Class A limits
Inverters promise down-to-earth value
By cutting out nonessential features, the Lenze smd range of inverters brings new economy to 25% of the inverter market.
The company manufactures two types of film projector: models with the traditional Maltese Cross drive, a proven and robust mechanism, and Kinoton's own patented design with an electronic intermittent sprocket drive.
This solution gives improved picture quality in terms of brightness, picture steadiness and freedom from flicker.
It is capable of running up to 100 frames per second and is, therefore, suitable not only for cinemas but also for processing laboratories and film archives.
Kinoton's equipment is found in cinemas worldwide, including nearly 60 cinemas in England alone.
Both types of projector are fitted with Lenze geared motors and Lenze smd frequency inverters, rated at 0.25 or 0.37kW.
Kinoton chose the smd for its low cost and ease of setup - the integrated keypad making additional components unnecessary.
Also the compact dimensions of the smd meant that it could be mounted right alongside the electric motor.
The unique EPM memory chip stores the entire inverter configuration along with motor parameters and plugs into the front of the smd.
Copying the settings is easily done in a battery powered programmer, a task that takes less than 3s, and the new EPM chip can transfer those settings to a new inverter even without the need to power it up.
The Lenze smd is ideally suited to sensitive mechanisms such as film projector drives with soft acceleration as well as seamless transition when changing direction of rotation.
Overload protection for the motor is integrated with microprocessor calculation of the motor load level independent of output torque, making additional protection hardware unnecessary.
The Development Manager of Kinoton, Gerald Wilke, states: "The synthesis of product quality, operational safety, user-friendliness and minimal maintenance along with reliable and prompt service has resulted in satisfied customers the world over for more than 50 years".
