Proven power electronics provide reliable operation and components are accessible from the front of the unit for quick, easy serviceability and maintenance.
A Rittal TS8 enclosure system in IP21 (NEMA1) or IP54 (NEMA12) enables easy system expansion, while a Class A1 RFI filter (optional class A2) reduces EMI/RFI without the need for external filters.
Additional features include DC-link reactors to reduce harmonics without external AC line reactors, DC-link fuses that provide independent protection of inverters and coated PCBs that provide extra protection in potentially corrosive environments.
High power F-frame VLT series variable frequency drives also feature a cooling design that uses a ducted back channel to pass cooling air over heat sinks, with minimal air passing through the electronics area.
This allows 85% of the heat losses to be exhausted directly outside the enclosure, which improves reliability and prolongs drive life by dramatically reducing temperature rise and contamination of electronic components.
A number of power, monitoring, enclosure, filtering, control and convenience options and accessories are available to enhance performance and operation.
