The Altivar ATV212 inverter drive is a recent updated version of the earlier version ATV21 variable speed motors from Schneider Electric. This VFD drive has an output frequency control of 0.5 to 200Hz, The Altivar 212 HVAC drive has been built for performance, intelligence and protection.

• It’s important that the drive is mounted in a dust and damp proof enclosure whilst in certain environment such as dust, corrosive gases, and high humidity also around any dripping or splashing liquid. This is to protect the drive and to ensure that whilst in the enclosure the maximum internal temperature can reach 50 °C. To help encourage efficient circulation, we recommend that you fit ventilation grills and remove the blanking cover from the top of the drive. Please refer to the datasheet for more information regarding this.
• The communication service allows the user to monitor inhibitable, read device identification, read holding registers, configure a time out setting, and write multiple registers and write a single register.
• Features an integrated class C2 EMC filter.
• The Altivar is a frequency controller for a three phase, squirrel cage motor.
• Available as standard IP21 and IP55 protection
• Electrostatic discharge immunity test level 3, conforming to IEC 61000-4-2.
• Less than 35% THDi harmonics due to Innovative C-less technology
• Embedded Building management communication protocols.
• Incorporates 3 logic inputs, 2 analogue inputs, 2 logic outputs and one configurable analogue output.

• Typically used in industrial and commercial applications, mainly focusing on ventilation due to the lack of airdraulic noise and motor noise.
• Smoke extraction which has a forced start with fault inhibition.
• Heating and Air conditioning, because of the optimised control in fluid processing and adjustable flow rates which improves energy management.
• Pumping, useful in this application because of the multi-motor configuration and sleep/wake function. Alongside the detection of underload/over load.

The fan control strategy of the ATV212 means that the fans will start when the drive is in the “RUN” state. The fan will then stop after the “STOP” command has been given. There may be a time delay because of the thermal state.

This Altivar 212 variable speed drive can feed 3-phase asynchronous motors. Its protection index is IP55 and it has a built-in EMC filter. It works at a rated power up to 37kW / 50hp and a rated voltage from 380V to 480V AC. Its design is based on eco-energy with a reduction in energy consumption of up to 70% compared to a conventional control system. Thanks to its cable temperature rise reduction technology, the Altivar 212 drive offers immediate, disturbance-free operation avoiding additional options such as a line choke or DC choke to deal with current harmonics. It weighs 57.4kg and its dimensions are, 284mm wide, 880mm high, 343mm deep. It is specifically designed for the most common fluid management applications in tertiary sector buildings (HVAC) like heating, ventilation, air conditioning and pumping. It conforms to international standards IEC/EN 61800-5-1 and IEC/EN 61800-3 (immunity and conducted and radiated EMC emissions). It is also CE, UL, CSA, C-Tick and NOM certified. The Altivar 212 offers optional motor chokes which can increase the maximum cable lengths between the drive and the motor and limit disturbance at the motor terminals. It is designed to be mounted in vertical position (+/- 10 °) on a panel, thanks to 4 fixing holes. The Altivar 212 drive can easily be adapted to all building management systems thanks to its numerous functions and communication protocols integrated as standard, Modbus, METASYS N2, APOGEE FLN P1 and BACnet.
