Type:  AC/DC Drive Control
Description:  The Altivar 38 is a frequency inverter for three-phase asynchronous motors powered by a three-phase supply 380 V + 10% to 460 V + 10% or 480 V + 5% in the power range 0.75 kWto 315 kW. The Altivar 38 has been designed for state-of-the-art applications in heating, ventilation and air conditioning (HVAC) in industrial and commercial buildings: ventilation, air conditioning, pumping. The Altivar 38 can reduce operating costs in buildings by optimizing energy consumption while improving user comfort. Its numerous integrated options enable it to be adapted to and incorporated into electrical installations and sophisticated control systems. The need for electromagnetic compatibility was taken into account at the outset of designing the drive. Depending on the drive rating, filters and chokes are either built-in or available as optional accessories.
Connectivity:  Modbus
Features:  The Altivar 38 is supplied ready for use in pumping and ventilation applications. It comprises a terminal that can be used to modify programming, adjustment, control or monitoring functions to adapt and customize the application to meet individual customer requirements: Specific functions for pumping/ventilation; Protection functions. It is easy to integrate into control systems with 4 logic inputs, 2 relay outputs, 2 analogue inputs and 1 analogue output; Plug in I/O connectors; Display of electrical variables and operating indicators; RS 485 multidrop serial link with Modbus protocol as standard in the drive. This serial link can be used to connect PLCs, a PC, communication gateways or one of the available programming tools.
Specifications:  RS 485 on RJ 45; 4800 to 19200 bps
