VF1A Doesa variable frequency drives (VFDs)
IDEC Corporation now offers a new line of VF1A Doesa variable frequency drives (VFDs), providing versatile control and efficient operation of electrical motors for a wide range of applications.
Control and efficiency
VFDs are used to control the speed and torque of AC motors so users can optimize system performance by running equipment at just the speed required to meet the demand of the load. Furthermore, VFDs are configurable to accelerate and decelerate to commanded speed smoothly, reducing the wear and tear on associated mechanical components. Among the greatest of VFD benefits is the energy savings realized by running a motor at any speed below maximum, so long as the equipment needs are met.
IDEC VF1A Doesa VFDs are suitable for speed control of variable and constant torque applications ranging from fans and pumps to specialized equipment. The VFD is capable of driving an induction motor (IM) or a permanent magnet synchronous motor (PMSM). IMs can be driven in open loop or closed loop, while PMSMs can be driven in open loop only
The product family features a compact form factor in a UL open-type construction, with nickel- and tin-plated bus bars and conformal coatings for corrosion protection. The VFD is designed for a long operating life, and provides a maintenance alarm signal.
Electrical input is nominally rated as three-phase low voltage AC 400V (with an allowable input voltage range of 380-480V AC), and the VFDs come in 14 models.
