Altivar 212

Schneider Electric – Altivar 212 – VFD for HVAC Application

Presentation

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 over torque: 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
  • Anti-harmonic technology enables a THDI < 30% to be achieved

Benefits

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, anti-harmonic technology (THDI ˜ 30%).

Applications

Ventilation:

  • Less noise pollution.
  • 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 under load/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.
