Inverters-FREQROL-D800 Series Wide range of applications

Improved freedom of panel design through a compact body

Effective solution for downsizing of the enclosure

Side-by-side installation

Side-by-side installation is possible to install multiple inverters in close contact. Users can select the most suitable layout for the intended installation area.

  • ND rating: Allowed for the surrounding air temperature of 40℃ or lower
  • SLD rating: Allowed for the surrounding air temperature of 30℃ or lower

Further reducing the external size

The external size (width) of some capacity models have been reduced.
Installation interchange attachment options will be available for facilitating replacement.

Double rating (ND rating, SLD rating) NEW

For the FR-D800, the SLD rating is added (double rating, the initial status is the ND rating), and the appropriate rating can be selected with parameters. For light-load applications such as fans and pumps, using an inverter with a capacity smaller than a motor by one rank with the SLD rating can reduce the size, weight, and cost of the system.

Selecting a resistor according to the application reduces the installation space inside the enclosure

Built-in brake transistor

The enhanced power regeneration capability (brake duty: 100% max.) is supported. High regenerative braking operation can be performed without a brake unit.

  • *2: The brake duty is 30% ED maximum when the lowest resistance value is used.
    The brake resistor must have a sufficient capacity to consume the regenerative power.

(Application example)

Use in harsh environments

Circuit board coatingNEW

Various applications are supported by allowing for corrosive environments or a wide range of surrounding air temperatures.
The circuit board coating (conforming to IEC 60721-3-3:1994 3C2/3S2) is provided for improved environmental resistance.

Filterpack is available

The Filterpack (FR-BFP2) is available as an option. The power factor improving DC reactor, common mode choke, and capacitive filter (radio noise filter), that are essential for air conditioning applications, are included in a Filterpack.
