Schneider AC Drive
Product Code : Altivar 312 AC Drive
Brand Name : Altivar
Product Description

Our company is the prominent manufacturer and exporter of an excellent range of 312 AC Drives. This drive is installed for providing an effective speed control in asynchronous motors from 0.25 to 20 HP. These drives are specially engineered for pumping applications. The 312 AC Drives accelerates the production rate. Our team of quality controllers strictly test these drives based on standard quality parameters.


  • Compact designs
  • Highest over-torque
  • Available with a remote graphical keypad


The Altivar 312 drive is a frequency inverter for 2 00…600 V three-phase
asynchronous motors from 0.18 to 15 kW. The Altivar 312 drive is robust, compact and easy to install. Its integrated functions
are particularly suitable for the requirements of applications involving simple
industrial machines.
By taking account of constraints on product setup and use right from the design
stage, we are able to offer a reliable, cost-effective solution to manufacturers of
simple machines and installers.
With its various communication cards that are available as options, the Altivar 312 drive integrates perfectly in the main control system architectures.

The Altivar 312 drive incorporates functions that are suitable for the most common
applications, including:

  • Material handling (small conveyors, hoists, etc.)
  • Packing and packaging machines (small bagging machines, labelling machines,etc.)
  • Special machines (mixers, kneaders, textile machines, etc.)
  • Pumps, compressors, fans

The Altivar 312 drive has six logic inputs, three analog inputs, one logic/analog
output and two relay outputs.
The main functions available are as follows:

  • Motor and drive protection
  • Linear, S, U or customized acceleration and deceleration ramps
  • Local control of the speed reference using the navigation button
  • +/- speed
  • 16 preset speeds
  • PI regulator and references
  • 2-wire/3-wire control
  • Brake sequence
  • Automatic catching a spinning load with speed detection and automatic restart
  • Fault configuration and stop type configuration
  • Saving the configuration in the drive
  • Several functions can be assigned to one logic input.
