Description
IVR 400T (37 kW, 400 V, 75 A) – three-phase inverter, intelligent pump controller
The IPRO IVR 400T controller is an inverter designed for direct connection to three-phase submersible, surface and immersion pumps with power ratings from 11 to 45 kW. The device maintains a constant preset water pressure in the system by smoothly varying the pump motor speed, which reduces energy consumption and extends the pump's service life.
Who is it for?
- Industrial and agricultural system installers – simple push-button operation and no need for specialist programming shorten the commissioning time for larger pumping systems.
- Farms – pump operation control for water supply from wells and for irrigating greenhouses, gardens and fields.
- Industrial plants and systems – constant water pressure in extensive water supply systems requiring higher pumping capacities.
- Multiple-pump systems – the ability to connect controllers into a pumping group makes it easier to manage higher water demand.
Applications
The IVR 400T controller works with three-phase submersible, surface and immersion pumps, controlling their operation to maintain the preset water pressure in a system supplied from a well or another water source. It is used on farms, for water supply from wells, irrigation of greenhouses, gardens and fields, rainwater collection and use, as well as in industrial equipment requiring regulated water supply at higher power than a typical domestic system.
The device must be installed in a location protected from direct sunlight, dust, moisture and corrosive or flammable gases. The IVR 400T 400 V pump controller allows you to select a power version suitable for the size of the system.
Features of the IVR 400T controller
The IPRO IVR 400T controller uses a microprocessor-controlled inverter that regulates the speed of the three-phase pump motor according to the current water demand. Thanks to the PID controller and operation with a pressure sensor, the device can reduce energy consumption by up to 30–60% – depending on the nature of the system and the water usage profile – compared with powering the pump directly from the mains.
The built-in soft-start and soft-stop function limits water hammer caused by the sudden starting or stopping of liquid flow, further extending the pump's service life. The controller features dry-run protection that operates without the need to install an additional sensor in the well, and all operation – including setting the operating parameters – is performed using the buttons on the housing.

Frequently asked questions (FAQ) – IVR 400T pump controller
What is the IVR 400T controller used for?
The IPRO IVR 400T controller is used to maintain constant water pressure in a system by regulating the speed of the motor in a three-phase submersible, surface or immersion pump with a power rating from 11 to 45 kW.
How does multiple-pump operation work in the IVR 400T controller?
In a multiple-pump system, up to 6 IVR 400T controllers are connected via an RS485 bus, with each one controlling its own pump. One inverter acts as the primary controller – it measures pressure with a transducer and controls the entire group – while the others work as auxiliary controllers and do not require their own transducers; the primary inverter starts and stops additional pumps depending on water demand. To balance wear, the units operate alternately – by default, the lead pump changes every 8 hours. The system is fault-tolerant: a backup primary inverter automatically takes over control when the main one stops working, and a faulty unit is bypassed in favor of the next one.
How does the IVR 400T controller protect the pump and system?
The device features protection against overload, overvoltage, undervoltage, short circuits and rotor lock, as well as dry-run protection that operates without the need to install an additional sensor in the well. The soft-start and soft-stop function limits water hammer in the system.
Do installation and operation of the IVR 400T controller require specialist knowledge?
The controller is operated exclusively using the buttons on the housing, with no need for specialist programming. The device should be installed by a specialist in a location protected from direct sunlight, moisture, dust and corrosive or flammable gases, in accordance with the operating instructions supplied with the product.
Where can I buy the IVR 400T controller manufactured by Dambat?
Dambat does not sell directly to customers. The IVR 400T controller is available from sales partners, installation wholesalers and authorized online distributors.
What are the warranty terms for the IVR 400T controller?
IPRO – 36 months (3 years) manufacturer's warranty. Warranty and post-warranty service provided by Dambat.
