Features:

  • Built-in HVAC Energy Optimization
  • Seamless BMS Integration & Fieldbus Flexibility
  • Rugged Design for Harsh Electrical Environments
The Schneider Electric ATV21HD11N4 features a dedicated "Energy Saving" control mode that dynamically adjusts motor voltage and flux based on real-time load demand. Unlike general-purpose drives, it is specifically optimized for centrifugal loads such as fans and pumps, where even small speed reductions yield significant power savings. By automatically adapting to pump/fan affinity laws, it reduces energy consumption by up to 30% compared to fixed-speed operation. Additionally, the drive includes an adjustable PI regulator, enabling direct pressure or flow loop control without the need for external controllers.

The Schneider Electric ATV21HD11N4 comes standard with a native Modbus RTU port (RJ45, 2-wire RS485) and supports optional plug-in cards for BACnet, LonWorks, Metasys N2, and Apogee FLN protocols. This flexibility allows the drive to integrate seamlessly into both legacy and modern Building Management Systems (BMS) without requiring additional gateway hardware. As a result, facility managers can achieve remote monitoring, real-time setpoint adjustments, and centralized alarm handling, significantly improving operational visibility and control over HVAC networks.

Engineered for reliability in electrically noisy environments, the Schneider Electric ATV21HD11N4 incorporates an integrated Class A EMC filter compliant with EN 55011, effectively reducing conducted and radiated emissions that can disrupt control signals from contactors, relays, or adjacent drives. Its IP21-rated enclosure (with top cover installed) protects against falling dirt and dripping water, while the coated PCB and wide operating temperature range (-10°C to 50°C) ensure stable performance in mechanical rooms or outdoor-rated enclosures. With 15g shock resistance, this drive is built to withstand the physical demands of industrial panel installations.

The ATV21HD11N4 Schneider Electric 11kW / 15HP HVAC Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Schneider Electric ATV21HD11N4 is a variable speed drive engineered specifically for HVAC applications such as centrifugal fans, circulation pumps, and air handling units. Operating on a 380–480V three-phase supply, it delivers 11kW (15HP) of motor control with a nominal output current of 22.5A and a 60-second overload capacity of 120%. Its compact form factor (180×232×170 mm) and lightweight design (6.45 kg) make it ideal for panel integration in commercial buildings and industrial facilities.

Equipped with integrated Modbus RTU (RJ45, RS485) and configurable analog/digital I/Os, the Schneider Electric ATV21HD11N4 enables seamless communication with building management systems (BMS) such as BACnet, LonWorks, and Metasys N2 via optional plug-in cards. The drive supports multiple control modes, including sensorless flux vector control, energy-saving quadratic V/F, and standard V/F with IR compensation, allowing optimization for both energy efficiency and process stability.

With an IP21 overall rating (IP41 top) and integrated Class A EMC filter, the Schneider Electric ATV21HD11N4 ensures reliable operation in electrically noisy environments and compliance with EN 55011 standards. Although discontinued since November 2020, it remains a widely referenced and supported model for legacy system upgrades, with clear migration paths to Altivar Process and Altivar Machine series.
