Modern and reliable frequency inverters

Astraada DRV frequency inverters are modern, reliable devices, easy to install, and despite the large configuration options easy to use. This makes the implementation and start-up quick and seamless.

Under the Astraada DRV name hides a cross-section of devices from universal low-power frequency inverters, through specialized devices for fans and pumps, up to technically advanced solutions controlled via Profibus DP, CAN, CANopen.

The family of frequency inverters in the Astraada DRV series consists of the following:

DRV-21 - Low power inverters

DRV-23 - Cost-effective frequency inverters

DRV-25 - Universal frequency inverters

DRV-27 - Frequency inverters for demanding applications

 

Easy of use and wide compatibility

Due to the variety of available features and protection functions, a wide range of power and a favorable price, Astraada DRV inverters meet the expectations of demanding industrial users and machine builders.

Communication via Modbus RTU bus, Profibus DP, Ethernet or CAN, the possibility of connecting a multifunctional LCD keypad with graphic display, built-in EMC filters, a multitude of available protection features ensure that Astraada DRV inverters are ideally suited for use in the manufacture of machinery, metallurgy, mining, the food industry, water and wastewater as well as in the wider HVAC field.
