Variable Speed Drive (ATV212)

The Variable Speed Drive (ATV212) is a variable speed drive for 3-phase asynchronous motors from 0.75 kW to 75 kW. This Variable Speed Drive (ATV212) is specifically intended for the most commonly encountered fluid management applications in tertiary sector buildings (HVAC): heating, ventilation, air conditioning and pumping. Due to the eco-energy based design of Variable Speed Drive (ATV212), energy savings of up to 70% can be achieved compared to a traditional control system. Characteristics
1. Altivar 212 covers motor powers between 0.75 kW and 75 kW on the following supplies :

• 200â�¦240V 3-phase, from 0.75 kW to 30 kW, IP 21
• 380â�¦480V 3-phase, from 0.75 kW to 75 kW, IP 21
• 380â�¦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
• nic technology enables a THDI < 30% to be achieved

• Preventative maintenance for reducing costs and optimising the equipment: fault alert, operating time, etc.
• Centered on Centralized Technical Management
• Instant viewing of the energy consumption
• Connection to building supervision network using embedded protocols.
• Detection of failures for quick intervention: belt breakage, pump running dry, phase failure, supply fault, etc.
• Centered on user-friendlines
• 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 â��Buildingâ�� series functions (fire mode, register monitoring, mechanical protection function, etc.

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