Series of converters VLT Lift Drive LD 302 productions Danfoss designed to ensure the safe and comfortable operation of elevator equipment (with traction pulley, hydraulic). The most practical design, the installation of this drive will take no more than 10 minutes. Asynchronous and synchronous (permanent magnet) motors are controlled with an open and closed circuit.
Intelligent capabilities allow you to reduce noise to a minimum, adjust the optimal cooling mode and save energy resources. Reliability of operation in harsh conditions is also ensured by a special coating of sensitive elements, boards. The rigidity of the structure ensures stable operation when exposed to vibration factors.
The model range is presented in one power rating, twelve dimensions are available in the range of small and medium capacities. Optionally, the housing can be completely protected from dust and water.
Applications: passenger elevators in medium and high-rise buildings, freight elevators, specialized lifts (ski, boat, etc.), shaft elevators, escalators, etc.
