Frequency converter Eco 2.2kW 3Ph-400V IP20

Features of Pump Applications

• Energy-efficient pump operation with variable speed
• Flexible pump station control without PLC or pump control unit
• with pipe break detection
• with dry run protection
• with warm-up function for motor
• with pump stirring cycle to remove sediment in the pump
• automatic adjustment of operating time and automatic pump switching
• automatic pump switching in the event of a pump failure
• with warning indication for each individual pump
• each pump can be switched to manual operation at the push of a button
• for pumps in wastewater applications, blockage/dirt detection and an automatic dirt removal/pump cleaning cycle can be set

Features of Fan Applications

• Energy-efficient fan operation with variable speed
• with belt detection
• Motor noise can be minimized by high switch frequencies (up to 32KHz), temperature-controlled cooling fan, and speed reduction
• Resonant frequencies can be skipped
• Multiple fan operation possible
• Compressed air ventilation system for stairwells to maintain pressure (approximately 50Pa). Ensures smoke-free escape routes in case of fire.
• Smoke gas extraction
• with fire mode override and longest possible functionality retention of the smoke extraction system
