IVR 11 (5.5-7.5 kW, 400 V) Inverter with sensor

The Intelligent Pump Controller, model IVR 11, is an easy-to-use control and protection device for direct connection of three-phase submersible pumps, surface pumps, submersible pumps, etc. with a power of 0.75 kW to 7.5 kW (from 1 HP to 10 HP), maintaining a constant, set water pressure by changing the rotational speed of the pump motor. The IVR 11 (also known as an inverter or inverter) is a frequency converter drive specifically designed to manage water pump performance to suit a wide range of water supply conditions and requirements. The IVR 11 drive allows the pump to operate more efficiently, safer and smarter, reducing energy consumption and extending the life of the pump. The IVR 11 drive is made of high-quality components and materials and uses the latest microprocessor technology.

The IVR 11 model has multiple operating modes by adapting to different electrical installations. IVR 11 series controllers can be used in pump groups of up to 5 pumps - a maximum of 1 master device and 4 auxiliary devices.

KEY FEATURES

1. Increasing energy efficiency. Compared to the traditional water supply method, a constant pressure system with a frequency converter saves energy by 30%-60%.
   
2. Long-term reliability of associated pumps: average torque and shaft wear are reduced due to a decrease in average rotational speed, which ensures a longer pump life. The built-in soft start and stop function of the device allows you to eliminate water hammer. (A water hammer effect is a sudden increase in pressure that occurs when a liquid flow stops or starts quickly.)
3. Comprehensive protection: the system has the most comprehensive protection technology for overcurrent, overvoltage, undervoltage, short circuit, blocked rotors, the ability to protect the pump against dry running without the need to install probes/sensors in the well.
4. Possibility to connect controllers into pump groups, up to 5 pumps. The group is controlled from one controller - selected by the user as the master - and the remaining controllers adjust their operation to the system requirements.

APPLICATION

The IVR-11 model is useful in all cases when it is necessary to maintain constant water pressure in the installation and to control and protect a single pump that manages automatic switching on and off by various electrical installations.

Select 1 and 2 for the main drive and 3 for the auxiliaries.

• Built-in PID controller: Advanced PID arithmetic to support closed-loop control.
• Stall speed control: Automatic current and voltage limitation during operation period,
• Master Drive Connector: Expandable RS485 design, one drive in the array can be master and controls other auxiliary drives (up to four) to operate in communication mode. The main drive sends PID feedback to the auxiliary drives and monitors their status in real time. Faults in auxiliary drives do not affect other drives.
• Water shortage protection: If the drive detects that the pipe pressure is lower than the set water shortage pressure value, the system automatically stops operating. After a certain period of time, it restarts automatically in certain cases. If the pressure returns to normal, the system operates normally. Otherwise, the system stops automatically, which extends its useful life to the maximum if the pump is idle.
• High pressure alarm: When the pressure exceeds the set value, the system stops working automatically, avoiding pipe damage due to high pressure.
• Auto Power Saving Mode: Automatically lowers the output voltage under light load to save power.
• Password setting: 4-bit password can be set using non-zero numbers. After exiting the setting interface, the password will be valid in 1 minute.
