Product Information

HYUNDAI N5000 Series

High Performance and Efficiency

\r\n
• Power Factor: over 0.95\r\n
  \r\n
  • No requirements for power factor correction capacitor
  \r\n
  • System Efficiency: over 96%\r\n
    \r\n
    • System efficiency is improved by connecting the power and motor without input-output filter and output transformer

Clean Power Input

\r\n
• A clean input wave is achieved via a secondary phase-shifted transformer
\r\n
• Without a filter, N5000 meets the stringent harmonic requirements of IEEE-519 (1992)
\r\n
• Protects the other equipment from harmonic disturbance
\r\n

Supplies of Clean Power for Motors

\r\n
• Output waveforms, without a filter, are close to sine waves due to multiple PWM control\r\n
  \r\n
  • No cable length & motor type restrictions
  \r\n
  • Existing motor can be used without modifications
  \r\n
  • Reduced noise and vibration of motors
  \r\n
  • 3.3kV - 13 level/6.6kV - 25 level output

Small footprint and economical maintenance

\r\n
• Small footprint and reduced installation costs due to no requirements for ancillary equipment such as input & output filter and the integral structure incorporating the input transformer and inverter panel
\r\n
• Thanks to the modular single-phase inverter of draw-out type, easy maintenance and time saving are achieved.
\r\n

Outstanding operation features by the improved sensorless vector control

\r\n
• Energy saving V/F control for the fluid load (Fan, Pump)
\r\n
• Inherent speed sensorless vector control of N5000\r\n
  \r\n
  • High starting torque operation
  \r\n
  • Control of current, speed and vibration of motor at the low speed range of light duty
  \r\n
  • Quick torque responsiveness and improved speed precision
  \r\n
  • Strong control regardless of motor specifications

Functions for trip-free operation (Option)

Improved Cell Bypass

\r\n
• In case of cell failure during operation, the faulty cell will be bypassed and the neutral point will be shifted (balance is restored through angle adjustment). 92% of the rated voltage can be output after the failure of one cell.
\r\n

Redundant Inverter Controller

\r\n
• If the master controller is out of service during operation, output is generated due to automatic switching to the slave controller
\r\n

Redundant Fiber-Optic Cable for CAN Communication

\r\n
• If there are problems with the optic cable during operation, an automatic switching to the standby reserve optical communication H/W is made
\r\n

Redundant Control Power

\r\n
• The redundant control power module is equipped with AC 440V and DC 120V and monitors the control power. In case of the failure of a control power module, an automatic switching to the reserve module is made
\r\n
