The Altivar 212 is a variable speed drive for 3-phase asynchronous motors from 0.75 kW to 75 kW. It is specifically intended for the most commonly encountered fluid management applications in tertiary sector buildings (HVAC): heating, ventilation, air conditioning and pumping. Due to its eco-energy based design, energy savings of up to 70% can be achieved compared to a traditional control system.

Characteristics:

• Altivar 212 covers motor powers between 0.75 kW and 75 kW on the following supplies:
  •200…240V 3-phase, from 0.75 kW to 30 kW, IP 21
  •380…480V 3-phase, from 0.75 kW to 75 kW, IP 21
  •380…480V 3-phase, from 0.75 kW to 75 kW, UL Type 12/IP 55
• Speed range: 1:50 
• Transient overtorque: 110% - 60 s.
• Integrated EMC filters, categories C1 to C3 depending on model
• Communication bus most commonly used on the market integrated: Modbus, METASYS N2®, APOGEE FLN P1® and BACnet®. Optional: LonWorks 
• Complies to international standards and certifications: UL, CSA, C-Tick and NOM
• Antiharmonic technology enables a THDI < 30% to be achieved

Lợi ích

Centred on Centralised Technical Management

• Instant viewing of the energy consumption.
• Detection of failures for quick intervention: belt breakage, pump running dry, phase failure, supply fault, etc.
• Preventative maintenance for reducing costs and optimising the equipment: fault alert, operating time, etc.
• Connection to building supervision network using embedded protocols.

Centred on user-friendliness

• Tools for installing, parametering and viewing the installation (remote graphic terminal in 6 languages, Multi-Loader, Bluetooth and SoMove Mobile).
• Compact size.
• Simple maintenance.

Centred on protection

• Continuity of service assured.
• Dedicated “Building” series functions (fire mode, register monitoring, mechanical protection function, etc.
• Integrated EMC filter, antiharmonic technology (THDI ˜ 30%).

Các ứng dụng

Ventilation:

• Less noise pollution (airdraulic noise, motor noise, etc.).
• Detection of transmission component breakage.
• Smoke extraction: forced start with fault inhibition.
• Automatic restart.
• Allows register management.

Heating and Air conditioning:

• Optimise control in fluid processing.
• Use of PID controller (temperature, flow rate, pressure, etc.).
• Adjustable flow rates for better energy management.
• Suppression of mechanical resonance.

Pumping:

• Detection of underload/overload, pump running dry.
• Multi-motor configuration.
• Limitation of operating time at low speed.
• Sleep/Wake function.
• Pressure surge suppression for prolonging the life of the installation.
