Medium voltage multi-level IGBT drives are smallest in class

By adopting an all-in-one structure, the E2 series has been made light and compact, thereby increasing the flexibility of installation, and improving efficiency in transport, installation, and maintenance operations. The unit is also IoT compatible, being equipped with data gathering and communication functions.

Hitachi will market these products targeting a broad range of fields throughout the world, including chemical, iron and steel, cement, and water treatment plants.

Inverter is an equipment to control motor speed depending upon operating requirements, and can reduce electric power consumption in fans, pumps, and other devices. In recent years, by the requirement of energy conservation, applying inverters to fans and pumps of process plants in order for efficient operation has become a trend.

In this situation, inverters for 2000kW or less motors have higher demand in steel, chemical and other process plant. On the other hand, limitation of installation space and efficient transportation, installation and maintenance has become matters and requirement for advanced facility operation and for IoT connectivity is increasing.

To meet these needs, installation area for the E2 Series is reduced by approximately 30% compared to existing models, by adopting optimum parts mounting technologies and cooling design technologies, and realised the smallest in class. In this way, the E2 series can be installed even in locations where space is limited. Furthermore, with its all-in-one structure, the E2 series can be transported without disassembly. This leads transport and installation operations more efficient. The unit is also IoT compatible, with functions for gathering and communicating data on facility operations. The compact size of the components of main circuit improves ease of maintenance.

Hitachi is strengthening the global competitiveness of its industrial product business, while at the same time focusing its efforts on enhancing products that can be linked through digital technologies. The HIVECTOL-HVI-E2 series of medium voltage multi-level IGBT drives was developed with the advanced motor control technologies and the extensive track record, accumulated over 80 years in the field of drive systems. Through the broad sales of these products, Hitachi will contribute to greater energy conservation in industrial fields.

Main features

1. The smallest inverter in class, it takes up very little space, so can be installed in locations with limited space available. This also enables transport more efficient, as it can be loaded in standard containers.
2. The all-in-one structure, combining the main circuit, control, and transformer components, enables efficient transport and installation operations using a forklift, with no need for disassembly.
3. Programmable Logic Controller (PLC) is installed as a standard feature. This enables the gathering and communication of facilities operation data, and Internet connectivity supports IoT compatibility.
4. The compact size of the components of main circuit, along with optimum circuit wiring, minimises time required for maintenance and inspections.
5. Auto tuning functions reduce the time of product implementation.
6. 15 year maintenance services (long-term comprehensive maintenance and long-term warrantee are offered as an option.
