Discover the engineering advantages that set the AT24 UB HP apart - and keep your operations running at peak performance.

The drive features a fully welded, sealed cabinet that ensures structural integrity and protects against heavy dust and water ingress, eliminating the need for additional external protective enclosures.
Designed with a dedicated cooling channel that isolates power components from sensitive electronics, this system operates without air filters, removing the need for cleaning or replacement and reducing failure risks.
The DC link exclusively uses polypropylene capacitors which, unlike standard electrolytic types, do not require reforming after long storage and offer a significantly extended service life.
Built-in Wi-Fi connectivity enables wireless commissioning and control via a smartphone or laptop in under 10 seconds, allowing users to configure the drive without opening the enclosure.
Engineered for direct outdoor installation, the unit includes UV-resistant powder coating, heat-reflective cabinet colors, stainless-steel external fasteners, and membrane vents to drain condensate.

The series supports versatile installation methods, including wall-mounting for lower power units and free-standing setups with integrated mounting bases for high-power models (standard on 280–400 kW).

The drive utilizes an intelligent controller that adapts to varying environmental conditions to ensure optimal performance and reliability under all operating scenarios, including changes in temperature.

Look inside the AT24 UB HP to see how smart design becomes real-world performance, efficiency, and uptime.
