Lenze's IP65 SMV frequency inverters now have the option of a polycarbonate casing to give protection from the ultraviolet radiation present in sunlight. These inverters were originally designed for factory environments with washdown, but the IP65 enclosure allows use outdoors. However, standard plastic casings suffer from medium-term degradation due to the ultraviolet rays present in direct sunlight. With the optional polycarbonate casing, the inverters are suitable for use outdoors in exposed locations.
Nine sizes of SMV inverter drive cover powers from 0.25-7.5kW with a three-phase 400V supply or up to 2.2kW with a single-phase 230V supply. A simple integrated keypad allows local control and display of status. Alternatively, modules for the following fieldbuses can be incorporated: Profibus, CANopen, DeviceNet, Modbus and Ethernet. The inverters feature the Lenze EPM memory chip that holds the drive's parameters and allows easy transfer of settings from one drive to another, thereby saving time during installation and maintenance.
The benefits of putting an inverter with high enclosure protection close to the motor can be easily seen: the required panel size is reduced; also power connections that would have been run with shielded cables from the panel to the motor can now be replaced by standard cables; and installation time is reduced.
Lenze SMV inverters are designed and approved for use worldwide: CE and RoHS for Europe; UL and cUL for the Americas; GOST for Russia; and C-Tick for Australia and New Zealand.
