ALTIVAR 28 As a frequency converter for three phase asynchronous squirrel cage motors, the Altivar 28 incorporates the latest technological developments such as 3rd generation Power Components etc. The Altivar 28 is robust, compact and conforming to international standards.Created from our experience of producing over several generations of speed, controllers, its functions meet the requirements of the most up-to-date applications such as:

• HORIZONTAL MATERIAL HANDLING
• PUMPS & BLOWERS (for energy saving)
• PACKING & PACKAGING
• TEXTILES
• HVAC (heating, ventilation & air conditioning)
• SPMs (special purpose machines)
• AGITATORS / MIXERS
ALTIVAR 28
FREQUENCY CONVERTOR FOR 3Ø ASYNCHRONOUS
   
 

ELECTROMAGNETIC COMPATIBILITY:
The ATV28 speed controller has built-in EMC / RFI filters. The incorporation of filters in the speed controller simplifies installation and reduces the cost of conformity to CE marking. ATV28 confirms to following standard

EN 61800-3 /IEC 1800-3 domestic and industrial environments
