Sun protection for outdoor inverters

Sun protection for outdoor inverters
The Lenze SMV frequency inverters with IP65 enclosure now have the option of a polycarbonate casing to give protection from the ultraviolet radiation present in sunlight.

SMV inverters were originally designed to withstand washdown in factory use, but the IP65 enclosure allows use outdoors. Here standard plastic casings suffer from medium-term degradation in direct sunlight, but the new polycarbonate casing option gives long-term suitability for use in exposed locations.

Nine sizes of SMV cover powers from 0.25 to 7.5kW with either three phase 400V supply or single phase 230V supply up to 2.2kW. A simple integrated keypad allows local control and display of status. Alternatively modules for a wide range of fieldbuses can be incorporated - PROFIBUS, CANopen, DeviceNet, Modbus, Ethernet. 

Being able to put an inverter outside with its motor means panel size can be reduced, power connections are simplified and installation time is reduced. These inverters feature the Lenze EPM memory chip which holds all the parameters for the drive. The EPM allows easy transfer of settings from one drive to the next, saving time at installation and maintenance.
