Distribution Lines Lenze

Lenze frequency inverters are used for electronic speed adjustment of drives in many industries and applications. The smd frequency inverter - a new member of the Lenze product range - meets the requirements of standard applications such as: 

  • easy implementation
  • simple speed adjustment
  • functions like acceleration, deceleration, reversal
  • protective functions

Lenze smd - the perfect partner for standard applications in the power range 

  • from 0.25 to 2.2 kW, 230 V single phase,
  • and 0.37 to 22 kW, 400 V 3-phase

Compact design
This wide power range provides a compact design that is the ideal balance of performance and size.

Innovative EPM memory chip
The EPM is the "heart" of the Lenze smd. The pluggable EPM stores all of the smd parameter settings. The EPM can be unplugged and programmed or copied outside the frequency inverter. If required, it can also be used in other smd inverters. The programming effort and system downtimes considerably reduced.

High overload capacity 150% Ir for 60 seconds. Compliance with CE, UL, cUL.

Quick commissioning
Quick commissioning is possible using the integrated keypad and the
functions pre-configured for standard applications.

Quick installation
Integrated RFI measures on single-phase models and easily accessible control and power
connections reduce installation times to a minimum.
