150% Torque IP66
Drive capacity to maintain a overload (over torque) of 150% of the rated current of the drive for 60 seconds every 10 minutes , with IP20 / IP21 protection to install in an electrical panel.
The electronic speed variators 150% Par IP20 ( VDF ) allow to regulate the torque delivered by a device without resorting to uneconomic options, which demand more energy than required or which are impractical in many cases; as a good example of this: the recirculation of the fluid, the throttling of the flow through valves ( throttle ) and the stopping of the equipment ( On-off ).
These devices allow to achieve considerable energy savings in the operation of electric motors and other additional benefits, such as prolongation of the useful life of the equipment driven by the motors, lower noise, less wear, better control and possibilities of regeneration, in relation to engines that do not have this device.
Recent studies show that pumps require only 31% of used energy, compressors 18% , fans and dryers 18% and the conveyor belts close to 14% .
The loads that have a variable moment are the best candidates to add a VDF to save energy.
The fans and centrifugal pumps are loads of variable torque where the required power varies with the hub of the speed, this way to reduce the speed of operation will decrease the power required by the motor and the energy saving comes from reducing the speed of the motor .
This fact means that pumps and fans VDF allow a energy saving of 50% or more .
