The Altivar 21 is an energy saving drive for simple three phase motors.
We carried a range of the Altivar 21 inverter in stock, but it has been superseded by the Altivar 212, which we do carry and can offer short lead times or suitable alternatives to any that are out of stock. Otherwise we can offer to repair your Altivar 21.
