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 :
- 200240V 3-phase, from 0.75 kW to 30 kW, IP 21
- 380480V 3-phase, from 0.75 kW to 75 kW, IP 21
- 380480V 3-phase, from 0.75 kW to 75 kW, UL Type 12/IP 55
2. The dual port enables a dialogue tool and a communication network to be connected at the same time.
- 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
Benefits - 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 Building series functions (fire mode, register monitoring, mechanical protection function, etc.
Applications - 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
