Get Price Quote
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.
Characteristics1. 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 21380â¦480V 3-phase, from 0.75 kW to 75 kW, IP 21380â¦480V 3-phase, from 0.75 kW to 75 kW, UL Type 12/IP 552. The dual port enables a dialogue tool and a communication network to be connected at the same time.
Speed Range : 1:50Transient Overtorque : 110% - 60 s.Integrated EMC filters, categories C1 to C3 depending on modelCommunication bus most commonly used on the market integrated: Modbus, METASYS N2®, APOGEE FLN P1® and BACnet®. Optional: LonWorksComplies to international standards and certifications: UL, CSA, C-Tick and NOMnic technology enables a THDI < 30% to be achieved
Benefits
Preventative maintenance for reducing costs and optimising the equipment: fault alert, operating time, etc.Centered on Centralized Technical ManagementInstant viewing of the energy consumptionConnection 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-friendlinesTools for installing, parametering and viewing the installation (remote graphic terminal in 6 languages, Multi-Loader, Bluetooth and SoMove Mobile)Compact sizeSimple maintenanceCentred on protectionContinuity of service assured.Dedicated âBuildingâ series functions (fire mode, register monitoring, mechanical protection function, etc.
Applications
Ventilation
Less noise pollution (airdraulic noise, motor noise, etc)Detection of transmission component breakageSmoke extraction: forced start with fault inhibitionAutomatic restartAllows register managementHeating and Air conditioning:
Optimize control in fluid processingUse of PID controller (temperature, flow rate, pressure, etc.)Adjustable flow rates for better energy managementSuppression of mechanical resonancePumping
Multi-motor configurationDetection of underload/overload, pump running dryPressure surge suppression for prolonging the life of the installationSleep/Wake functionLimitation of operating time at low speed
