Toshiba’s T300MVi® medium voltage adjustable speed drive is the most advanced drive in the industry. No other drive in the market features the latest multi-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, a lower cost. In addition, it incorporates the latest safety technology, making it one of the safest designs on the market.
Variable Frequency Drives
MTX NEMA 3R MV Outdoor Drive
Severe Duty Outdoor – The Toshiba MTX® NEMA 3R outdoor medium voltage adjustable speed drive is one of the most innovative adjustable speed drive offerings to date. Featuring an advanced enclosure design and power section topology, the MTX is the world’s first and only drive specifically designed for outdoor mounting in remote applications or applications where a building does not exist. From the jungle to the desert, the MTX can be mounted virtually anywhere, eliminating the need to find suitable indoor floor space.
Plus Pack LV Severe Outdoor
Severe Outdoor – Toshiba’s Plus Pack outdoor adjustable speed drive is revolutionizing the industry by combining Toshiba’s robust Plus Pack technology and Toshiba’s proprietary, ground-breaking Virtual Linear Pump (VLP) Technology.
VLP Technology allows the Plus Pack to directly, precisely, and linearly control pressure, temperature, level, or flow using single or multiple devices while balancing the load between them. This innovative drive is designed to withstand even the harshest of conditions and is engineered to provide tight speed control, while offering the industry’s most user-friendly operator interface.
Key Features
- Heavy duty outdoor duty NEMA 3R enclosure as standard
- Up to 1500HP low voltage
- Capable of 12 pulse or 18 pulse front end fantastic for harmonic mitigation solution
Patented 18-Pulse Autotransformer Technology
In order to reduce harmonic injection to the utility, the Plus Pack is available in 12-pulse and 18-pulse diode frontend designs. The 12-pulse drive can achieve a typical current Total Harmonic Distortion (THD) of 9% and must be used with a conventional drive-duty phase-shifting isolation transformer. The 18-pulse Plus Pack is furnished with built-in phase-shifting patented auto-transformer technology which eliminates the need for complicated cabling and allows for a perfect blend of reliability, cost savings, and a reduced footprint.
W7 LV Variable Torque
Variable Torque – The W7 adjustable speed drive is an 18-pulse drive specifically designed for water and wastewater applications, and for any centrifugal application where harmonics are of concern. Enclosed in a small footprint, the W7 features a phase-shifting transformer that is integral to the enclosure. In addition, the W7 includes standard features such as vector control, RS485/RS232 ports and a wide selection of communication options, ground fault protection, and motor/drive overcurrent protection.
The advanced Electronic Operator Interface features a backlit graphical LCD screen, user-friendly menu-driven programming, and a built-in encoder for programming and speed control.
