NORDAC PRO Variable Frequency Drive - SK 500P

Single product family with basic to advanced functions

  • Power range: 0.33 – 7.5 HP (0.25 – 5.5 kW). Available up to 30 HP (22 kW) mid-2022.
  • Protection class: IP20
  • Multi-protocol Ethernet interface for PROFINET IO, EtherNet/IP, EtherCAT, Ethernet Powerlink, and more
  • USB interface for voltage-free parameterization, even when the mains power is disconnected.
  • Universal encoder interface for use with SSI, EnDat, Biss, Hiperface, and more

The NORDAC PRO is a variable frequency drive suitable for all applications. Even the basic SK 500P model provides great versatility. The advanced SK 530P version extends the product's scope and functionality with optional SK CU5 modules. The SK 550P has even greater functionality, including an integrated multi-protocol Ethernet interface for easy connectivity to Ethernet-based control systems. Easy operation is achieved via a Bluetooth interface, an SD memory card for storage and transfer of parameters, firmware and operating data, as well as a USB interface which enables parameterization of the VFD “in the box”. Utilizing the latest technology and components gives these VFDs an extremely small footprint, saving space and allowing for fast, effortless installation.
