Frequency Converter VESSER IQ-E/T 2.2kW; 3x400V; max. 18A for Pump, Pressure Control, Control Unit for Water Systems

Product detailed description

The VESSER IQ-E/T frequency converter maintains constant pressure in the system by regulating the pump speed. It is an intelligent pump controller, easy to use, for direct connection to three-phase pumps (submersible or surface). The VESSER IQ-E/T maintains the set water pressure by changing the speed of the pump motor. It has several operating modes and adapts to different electrical systems. Protective functions of the VESSER IQ-E/T frequency converter Dry-run protection without the need to install probes/sensors in the well Protection against overcurrent / overvoltage / undervoltage Short-circuit protection Rotor lock protection How the frequency converter works for a pump: When a tap is opened or irrigation starts, the pressure in the system begins to drop. The frequency converter's control unit evaluates the situation via the pressure sensor and starts the pump. The pump speed is regulated so that constant pressure is maintained in the system even as demand changes. To put it more simply, this means that the frequency converter runs the pump at, for example, 17% at low demand, at 57% when water demand increases, and at 97% at high demand. The IQ-E/T 2.2kW frequency converter has very simple installation and intuitive control. The converter current and dry-run protection are pre-set. The pump is stopped, started, and has its pressure increased or decreased easily and quickly by the frequency converter whenever needed. It differs from on/off type devices in these important characteristics: Energy savings: A water supply system equipped with a frequency converter can save 30 to 60% of energy compared to traditional water supply methods. Easy operation: All functions can be started and stopped at the push of a button; no help from programming specialists is needed. Long-term reliability of the connected pumps: The average torque and shaft friction of the pump are reduced as the pump motor speed decreases, ensuring a much longer pump service life. A built-in soft-start and soft-stop function limits water hammer (the water hammer effect means a sudden increase in pressure when liquid flow is stopped or started quickly). Comprehensive protection: The system is equipped with overcurrent, overvoltage, undervoltage and short-circuit protection, impeller lock protection, and dry-run protection without the need to install sensors in the borehole. Ability to connect converters into a set of up to 6 pumps. The set is controlled from one converter selected as the master, and the other converters adjust their operation according to the system's requirements. Programming the set is very simple and does not require the assistance of a technician. Use: family houses, apartments, cottages agricultural businesses pumping water from a well watering greenhouses, gardens, fields industrial facilities Advantages: simple control, the converter is pre-set for immediate operation clear and simple menu a pressure sensor and wall mount are included in the package quiet operation Recommendation: We recommend setting the dry-run time "P 013" to 10 seconds, which will extend the pump's service life to the maximum extent.
