The ATV21HD11N4 from Schneider Electric is a variable speed drive engineered with efficiency in mind for HVAC applications, particularly for controlling pumps and fans. It operates seamlessly at a power supply voltage between 380 and 480 V, with an allowance for voltage fluctuation from 323 to 528 V. This drive supports a line current of up to 16.8 A when supplied with 480 V and 21.1 A at 380 V.

Designed for three-phase systems, the ATV21HD11N4 delivers a motor power of 11 kW, achieving a maximum horsepower rating of 15 hp. In terms of power characteristics, it showcases an apparent power of 17.1 kVA at 380 V. The modulation of the drive can be facilitated through its Modbus communication port, reinforcing its capability for connectivity within modern systems.

There is no impedance for the polarization type, increasing its compatibility with various setups. The device operates effectively across a power supply frequency of 50 to 60 Hz, ensuring versatility in application. It maintains a critical insulation resistance of at least 1 mOhm at 500 V DC for one minute, enhancing reliability under operational stresses. Data transmission rates of either 9600 bps or 19200 bps provide flexibility for integration and communication needs. The device also adopts an assembly style that includes a heat sink, which aids in thermal management for sustained performance during demanding applications.
