Comprehensive Line-up

■Series lineup (inverters, converters)

- Line-up features unit type and stack type, facilitating easy construction of large-capacity systems.
- The stack type offers support for up to 2,400kW (MD spec.) or 3,000kW (LD spec.) through direct parallel connection.

Three-phase 200V series

Three-phase 400V series

Three-phase 690V series

*1: Refer to "Ratings for intended use" on page 6 for specifications (applicable load).

*: Unit type inverters have built-in brake circuits as standard (160kW or less).

*: Configuration: Standard unit → Can be used with one set. Stack by phase → Categorized by phase, and one inverter set consists of three stacks.

*: Multiple inverters can be connected with a single PWM converter and diode rectifier.

*: Inverters can also be supplied with DC power (with generator, etc.) without the use of a converter circuit.

*: Capacity expansion (parallel operation)

Inverters

Direct parallel connection: One single-winding motor is driven by multiple inverters. (Drive is possible with up to three inverters)
Multi-winding motor drive: Specialized motor drive system with multiple windings around a single motor. (Drive is possible with up to six inverters)

PWM converters

Transformer isolation (parallel system): System used to isolate the receiving power supply system and converter with a transformer. It is necessary to equip each converter input with a transformer. (No. of parallel connection units: max. 6)
Transformerless (parallel system): System in which a PWM converter is connected directly to the receiving power supply system. There is no need to isolate with a transformer. (No. of parallel connection units: max. 3)
