Stand-alone frequency converter

• This frequency converter can fit with fixed speed pumps equipped with asynchronous or permanent magnet motors, in several applications, especially heating, air conditioning and pressure boosting.

• Full motor protection with thermistor evaluation
• Emergency operation with speed reduction in the event of excess temperature, undervoltage or malfunction of a mains phase
• Phase failure monitoring for main phase
• Real-time clock for time-based control
• Dedicated counter for inverter and motor operating hours, kWh counter, memory for standard messages
• Trend function (installed electronics to operate the data log)
• Standard cascade control, protects pump from running dry, no or low volume flow
• Energy-saving mode with standby mode function
• 4 internal PID controllers
• Smart Logic function with 10 measures for simple drive activities
• PM motor and synchronous reluctance motors can be operated using a device
