Features

Extensive capacity series

With this extensive capacity series available from 10 kVA to 600 kVA, the capacity can easily be selected to match the load.
In addition, by multiplexing the inverters, up to 3600 kVA (600 kVA x 6 inverter units) can be supported.

Easy maintenance and inspections

While the control unit is in operation or stopped it is possible to check various data and status conditions, which makes it extremely easy to review the system operating state including safeguard and abnormal conditions.
Traceback functions* are also available during.
(*) option

Panel front maintenance access

For units of 300 kVA or less, the plugin-type unit structure enables easy maintenance access simply from the front panel.
Even for units of 450 kVA or more, all are now easily accessible for servicing from the front panel alone.

Fanless cooling of individual units

We have eliminated the separate cooling fans in each unit and now only use a cooling fan for control panel.

Adoption of IGBT

We have adopted a Insulated Gate Bipolar Transistor (IGBT) device configuration for a faster control response, lower loss and more simplified inverter control circuit.

High-efficiency plant operations

High-efficiency plant operations can be achieved by exchanging power energy and regenerative energy with the DC distribution system over a common DC bus.
