Altivar 212 dedicated HVAC drives for motors up to 75kW
The Altivar 212 is a variable speed drive for three phase asynchronous motors from 0.75 kW to 75 kW. It is specifically intended for the most commonly encountered fluid management applications in buildings (HVAC): heating, ventilation, air conditioning and pumping. Schneider Electric has specifically engineered the drive for HVAC duty, energy savings of up to 70% can be achieved compared to a traditional control system.
Applying AC drives on centrifugal pump and fan applications is an excellent way to increase energy savings and reduce maintenance costs. By eliminating air flow dampers, inlet guide vanes, and throttling valves, and using an AC drive to control air and fluid flow, users have reduced both energy and maintenance costs.
Although AC drives from most manufactures have provided similar rates of energy savings, the Altivar 212 has been optimised for efficiency to provide additional savings in buildings. The ATV212 minimises the energy losses during power conversion to accurately control motors and reduced speeds.
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, IP 55
– 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:
– Antiharmonic technology enables a THDI < 30% to be achieved
– 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 applications:
– 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.
– 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.
