NORDAC PRO - SK 500P - Frequency Inverter

Frequency inverter for control cabinet installation

  • Power range: 0.25 kW – 37 kW (up to 160 kW in preparation)
  • Protection class: IP20
  • Simple system integration via multi-protocol Ethernet interface
  • Fast commissioning due to voltage-free parameterisation via USB port
  • Multiple axis operation controllable via multi-encoder interface

The control cabinet inverter for all drive applications

With its high level of functionality, the control cabinet inverter covers a wide range of applications. Even the Basic version SK 500P is highly versatile. The Advanced version SK 530P expands this range and can be further extended with the plug-in optional modules SK CU5. This allows for precise adaptation to application-specific requirements. Its strengths become most apparent in automated systems. 

  • High compatibility and easy integration into Ethernet-based control systems via integrated multi-protocol Ethernet interface (PROFINET, EtherNet/IP, EtherCAT, POWERLINK) 
  • Quickly ready for use thanks to voltage-free parameterisation via USB interface  
  • The integrated SD card serves as a storage medium for parameters 
  • Easy to use via an optional Bluetooth interface 
  • Low space requirements thanks to compact design in book‑size format 

Product versions

  • Power range: 0.25 kW – 37 kW
  • Single-phase 200–240 V, 3-phase 380–480 V 
  • Available as Basic and Advanced version 
  • Optional SK CU5 extension modules for the Advanced version
