The NORDAC PRO is a frequency inverter for all drive applications. Even in the basic SK 500P version, the NORDAC PRO provides great versatility. The advanced SK 530P version extends this scope and can be functionally extended with optional SK CU5 modules. The SK 550P has an integrated multi-protocol Ethernet interface for efficient connection to Ethernet-based control systems. Easy operation of the NORDAC PRO is achieved with a Bluetooth interface, an SD memory card as the parameter storage medium, firmware and operating data, as well as a USB interface which enables parameterisation of the voltage-free inverter “in the box”. Use of the latest components enables a very compact design and therefore space-saving installation.
