Rotary Design

Our line of rotary frequency converters covers a range of 6.25kVA to 2MW. This type of converter lends itself well to industrial, manufacturing, motor starting and outdoor application.

Model 75IND6050QVSS built for the US Navy in Curacao to provide shore power for their vessels.

This example shows the flexibility we have in our design. The entire system was mounted in a 20 ISO shipping container for use aboard a commercial ocean going vessel.

This is an example of our QV(Quietized Vertical Model. This unit is designed to provide a reduced foot print and sound attenuation for use inside the plant.

Standard Open Horizontal construction utilizing a unit mounted control panel. (Remote Panel Optional)

Standard Synchronous Open Vertical Construction with unit mounted panel.

Top is a standard analog metering system and on the bottom is shown the digital meter option.

Rotary line isolation set to provide clean power to the load and protect it from lightning strikes.
