ACTIVE DRIVER PLUS M/M 1.5 frequency converter - action DAB.ACTIVE DRIVER PLUS FM

Product detailed description

The IVAR Active Driver Plus M/M 1.5 is commonly used in residential and commercial heating and plumbing systems where stable pressure is essential despite varying flow rates. It supports applications such as circulation in hot water systems, underfloor heating, and small HVAC systems. Installers typically work with this unit in systems requiring precise hydraulic control, especially in scenarios where pump speed must adapt to load changes while maintaining consistent pressure levels.

This controller is ideal for integration into systems with variable demand, such as those with multiple zones or time-based operation. The device ensures that the pump operates efficiently and avoids unnecessary stress on the system by dynamically adjusting speed based on real-time conditions. It is particularly useful in systems where energy efficiency and long-term reliability are priorities.

Technical parameters

Installation and connection

Installation involves connecting the frequency converter to the pump motor using the appropriate wiring according to the manufacturer’s guidelines. The input side connects to the power supply, and the output side connects to the pump motor terminals. The mechanical connections are made using DN 1 1/4” male and DN 1 1/2” female threads. Ensure all electrical connections are secure and insulated to prevent short circuits or interference. A key step is verifying that the pump and converter are compatible in terms of voltage and phase requirements.

Common mistakes include incorrect thread alignment or using incompatible thread types, which can lead to leaks or improper sealing. Always confirm the direction of flow and the polarity of the electrical connections. A multimeter can be used to verify continuity and correct wiring before energising the system. After installation, test the pump under load to ensure the converter responds correctly to pressure changes and maintains the desired setpoint.

Compatibility and accessories

This controller is designed for use with centrifugal pumps that support variable frequency drive inputs. For complete functionality, ensure the pump is equipped with a compatible motor and that the system includes a pressure sensor if automatic pressure regulation is required. Additional accessories such as mounting brackets, sealing rings and junction boxes may be needed depending on the installation environment.

Technical background for designers

The Active Driver Plus operates by modulating the frequency supplied to the motor, which directly affects the rotational speed of the pump. This allows for proportional control of the flow rate and pressure in the system. The device includes several built-in protections, including dry-run detection, overload protection, thermal protection for the power stage, and voltage anomaly detection. These functions help prevent damage to the pump and extend its service life.

The controller is constructed using durable, heat-resistant materials suitable for continuous operation in industrial and commercial environments. Integration into the system requires careful consideration of the overall hydraulic balance and the characteristics of the pump curve. The efficiency of the system depends on the correct matching of the pump and the load profile of the installation. Regular monitoring of the system parameters ensures optimal performance over time.

Service and operation

Regular visual inspections should be carried out to check for signs of overheating, corrosion or loose connections. The display provides real-time feedback on system status and can indicate faults or anomalies. If any error codes appear, refer to the user manual for troubleshooting steps. It is important to record any recurring fault messages to identify potential issues with the pump or the electrical supply. No scheduled maintenance intervals are specified, but periodic checks are recommended to ensure continued reliable operation.

Frequently asked questions

Can the Active Driver Plus be used with non-DAB pumps?
Yes, provided the pump is compatible with variable frequency drives and the motor specifications match the converter’s output capabilities.

How is the operating pressure adjusted?
Through the user interface on the device, which allows setting and monitoring pressure values according to the system requirements.

What happens if the pump runs dry?
The built-in dry-run protection will detect the condition and either alert the user or shut down the pump to prevent damage.

Is the device suitable for outdoor installation?
It should be installed in a protected environment to avoid exposure to moisture and extreme temperatures, as specified in the manufacturer’s guidelines.
