HU series

The HU Series High-Frequency Converters are built to meet the demanding requirements of modern industrial automation and robotics applications. As industries increasingly rely on precise and energy-efficient solutions, these converters stand out for their advanced design and reliable performance. Developed with both power and precision in mind, the HU Series provides manufacturers and operators with a dependable tool to support a wide range of production processes where accuracy and efficiency are critical.

The series comes in two distinct models, each tailored to different operational needs. The HU 2000+ offers an output of 2 kW with a frequency range of 0.25–1.0 MHz, making it suitable for smaller-scale or highly precise applications. Meanwhile, the HU 5000+ provides a higher output of 5 kW within the same frequency range, addressing larger or more energy-intensive operations. This versatility ensures that businesses can choose a model aligned with their specific requirements, whether for compact automation systems or more robust industrial processes.

One of the defining features of the HU Series is its ability to deliver precise and energy-efficient heating with minimal heat penetration. In many manufacturing environments, the need for localized heating without compromising the surrounding material is crucial. Excessive or uneven heating can result in wasted energy, increased costs, or damage to components. By focusing on efficiency and precision, the HU Series helps reduce these risks, leading to better product quality and lower operational expenses. This makes the converters particularly valuable in industries such as robotics, where delicate components must be treated carefully, and in automation processes where consistency directly impacts overall productivity.

At the heart of the HU Series is a microprocessor-controlled design, which ensures repeatability and stability in operation. In practical terms, this means that once a set of parameters is established, the converter can reproduce the same results consistently across multiple production cycles. For manufacturers, this reliability translates into fewer errors, reduced downtime, and a more streamlined workflow. It also ensures compliance with strict quality standards, as each operation can be carried out with the same precision time after time.

The HU Series high-frequency converters are suited to a wide range of industrial automation and robotics processes, particularly where precision heating of thin materials is required. Key applications include:

• Soldering

• Heat treatment (hardening, annealing, tempering)

• Joining (shrinking)

• Forming (forging)

• Surface treatment (drying, preheating)

• Melting

• Sealing

• Indirect heating

• Specialised solutions (e.g., bonding, plasma generation)

These versatile systems bring enhanced energy efficiency and operational reliability to production environments across manufacturing, electronics, and advanced materials processing.

The HU Series is fully microprocessor-controlled, providing high stability and repeatability across processes. Operators can easily customise heating parameters and integrate the converters into existing automation systems. With external control interfaces and optional Profibus or Profinet connectivity, the software ensures compatibility with industrial robotics systems and complex production workflows.
