T300MVi
SMALL FOOTPRINT – LARGE SAVINGS
Toshiba’s T300MVi
®
4160 V medium voltage adjustable speed drive is the most advanced
drive in the industry. No other drive in the market features the latest five-level Pulse
Width Modulation (PWM) with Neutral-Point Clamping (NPC) technology. This advanced
technology allows for a smaller footprint, a reduced component count, and ultimately, lower
costs. In addition, it incorporates the latest safety technology, making it one of the safest
designs on the market.
• Three Cables In, Three Cables Out
• 24-Pulse Harmonic Cancellation Complies with IEEE-519-1992
• Higher True Power Factor (0.96) than Running Motors Across-the-Line
• Smaller Footprint Through Compact Power Modules, Standard Copper-Wound Isolation
Transformer, & Air-Cooling System
• Robust, High-Quality Medium Voltage IGBT Technology, Transistors, & Control Components
• Advanced Electronics to Reduce Component Count
• Additive Five-Level PWM Output Voltage with No Neutral Shift
• Ten-Year Mean Time Between Failures
ADVANCED FEATURES FOR MAXIMUM DRIVE PERFORMANCE
f A Three Cables In, Three Cables Out Feature incorporates a standard pad-lockable input fused disconnect switch
with a vacuum contactor and interlocked doors and eliminates the need for a secondary power source, improving
the safety of system personnel.
f A Small Footprint allows the drive to be easily retrofit and paired with medium voltage motors without upgrading
the motor insulation. Additionally, it eliminates the need for an output transformer and allows for the use of standard
bearings without grounding or isolation means.
f A 24-Pulse Isolation Transformer provides phase-shift cancellation capabilities, eliminating issues concerning
harmonic injections into bus-fed equipment. As a result, the T300MVi resembles a linear load on the incoming
AC line.
f Five-Level PWM Output closely simulates a true sinewave by employing several layers of switching devices to
provide a smooth output waveform to the motor, virtually eliminating motor failures caused by insulation stress and
long lead-length issues.
f Medium Voltage IGBT Technology has continually proven to be the most reliable and best performing means
of speed control in our adjustable speed drives. Toshiba has successfully developed, utilized, and mastered this
technology. The T300MVi pairs the most advanced transistor technology with the most robust multi-level topology
and controls it with one of the fastest industrial processors in the world.
f A Versatile Control Interface offers eight digital inputs, six digital outputs, two analog inputs, and eight analog
outputs as standard. Each of these input/outputs can be programmed to a variety of different functions for ultimate
flexibility.
f A Plain-English LCD Electronic Operator Interface (EOI) allows for quick, user-friendly programming. Faults are
logged containing date and time stamps.
f Toshiba’s Proprietary Windows®-Based WiTool Software is designed to offer a full range of programming and
monitoring tools. Operating data can be captured with the snapshot feature and up to 12 drive signals can be
trended. In addition, the
WiTool
offers trace-back data for detailed fault analysis.
