Intelligent Pump Controller - model IVR 02 M - is a control and safety device for direct connection of single-phase submersible pumps, surface pumps, submersible pumps, etc., with power from 0.37 kW to 1.5 kW (from 0.5 HP to 2 HP), maintaining a constant, set water pressure by changing the rotational speed of the pump motor. The IVR 02 M model (also known as an inverter or inverter) has many operating modes by adapting to various electrical installations.
FEATURES
- Energy efficiency: compared to the traditional method, the constant pressure water supply system with frequency converter saves energy by 30 - 60%.
- 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 soft stop function of the device allows you to eliminate water hammer (the water hammer effect means a sudden increase in pressure accompanying a quick stop or start of liquid flow).
- 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.
- Possibility to control the operation of two pumps supplying the system.
APPLICATION
The IVR 02 M model will work well wherever there is a need to maintain constant water pressure in the installation and to control and protect a pump or a set of two pumps.

- water supply from wells,
- irrigation of greenhouses, gardens and fields,
