I-MAT

Summary

Product identification

The I-MAT is a variable speed system driven by a frequency converter for motor control in various water applications. It is an integrated control system designed to manage a wide range of applications and operating modes.

Applications:

• Water supply
• Water transport and distribution
• Production and distribution of hot/cold water
• Water treatment

Pump Protections:

• Against dry running
• Against operations with closed connection ports
• Against overcurrent of the motor
• Against overvoltage and undervoltage of the power supply
• Against unbalance or missing supply phases

Operating limits

• Max Ambient Temperature: 50°C
• Altitude: No higher than 1000 m, inside closed environment
• Protection: IP55

Electrical

• Standard voltage: 400 V ±10% (380-415V) three-phase
• Input voltage: 3380V-10% ÷ 3480V+5%
• Output voltage: 0 ÷ 100% of the input voltage
• Input frequency: 50-60 Hz
• Output frequency: up to 70 Hz

Construction

The standard system comprises:

• Frequency converter
• Removable control panel
• Power terminal board
• Signals terminal board
• Cable glands

On request components:

• Adapter for motor mounting
• Adapter for wall mounting
• Pressure and temperature transducer
• Main switch
• Line filter and output filter

Operating Modes

The I-MAT frequency converters are equipped with software providing different operating modes:

• Constant pressure mode: Keeps pressure constant at a user-set value.
• Proportional pressure mode: Reduces pump pressure proportionally with water demand.
• Constant temperature mode: Keeps temperature constant at a specified system point.
• Constant flow mode: Changes pump speed to maintain constant flow through a flow meter.
• Fixed speed mode: Operates as a fixed speed pump, with speed set by the user or external signal.
• Night mode (optional): Reduces pump speed if system temperature decreases below a set value; usable with all other operating modes.

Control Panel

The I-MAT is equipped with an integrated control panel for system setup and parameter monitoring.

• Enclosure: IP55, rotatable, installable in remote positions using a cable with M12 connectors.
• Display: LCD custom display for system status and operating parameters.
• Controls: 2 scroll buttons and 4 set-up buttons for navigation, parameter changes, and pump control.

Optional Modules

Compartments on the front side of the frequency converter allow for connecting optional modules without dismantling the unit. An optional electronic card enables communication between multiple units, managing up to 6 variable speed pumps and up to 5 fixed speed pumps.
