VT230S

Description

• Meiden VT230S is the world �s most technologically advanced ACdrive range.The primary feature of the VT230S series is Multi-Mode operation.The five operating modes deliver,effectively,five technologies in a single drive. An obvious concern would be that this series is �a sledgehammer to crack a nut �,making the assumption that five technologies have been combined,along with their costs.In fact,the VT230S costs less than similarly rated drives because it delivers its awesome
  
• flexibility from an architecture built from scratch rather than the parts bin. Many price-sensitive applications which traditionally lead to the use of lesser drive technologies are precisely the situations in which the availability of advanced control techniques can deliver significant benefits.Benefits like lower energy consumption,quieter operation and ease of use.

SOFT SOUND

Meiden Soft Sound technology reduces the characteristic whine from inverter- driven motors AND eliminates the side- effects of conventional noise reduction methods ?specifically that of raising the carrier frequency. Soft Sound varies the carrier frequency in one of two fixed patterns,from a user-selected base frequency (between 2.1kHz and 5kHz).By keeping the carrier frequency range low,torque performance is notably better than a high-frequency carrier. The high frequency induced problems of hot running,degrading of winding insulation,arcing across motor bearings, high leakage currents and interference are eliminated.

MEIDEN PM MOTORS

• It has long been known that Permanent Magnet Motors offer efficiency advantages over standard 3-phase motors. By using a magnetised rotor,a proportion of the drive �s energy is not wasted inducing a magnetic field.Because less energy is wasted,less heat is created and in many applications,there is no need for a cooling fan.
• Meiden PM Motors are assembled in standard IEC-size frames for easy retro- fit and interchange with 3-phase motors, Specifying is made easier by rating each motor in kW (rather than Nm). The efficiency of Meiden PM Motors often enables a motor one size smaller to be specified.
