1. Built in CPU for digital control, increasing stability by 60%
The PDA series products adopt precise software algorithms, combined with high-speed CPUs, to achieve complete digital control, reducing the application of a large number of components. Compared to brake units controlled by analog circuits, the stability and reliability of PDA series products have been improved by over 60%.
2. Select IGBT and heat sink according to UL standards in the United States for safer and more reliable operation
The PDA series products strictly follow the UL safety standards in the United States, using high-quality IGBTs and heat sinks, and are equipped with four protection methods: overheating, overcurrent, short circuit, and overvoltage, making them safer and more reliable.
3. High standard production processes create higher quality brake units
Every industrial design of the PDA series products has undergone repeated consideration, in order to meet various complex working conditions, fully utilize the characteristics of various components, continuously optimize the internal structure, and ensure the stability, reliability, and high-quality user experience of the products.
4. Humanized design, adding normally open and normally closed alarm contacts
Fully considering user needs, users do not need to modify the circuit design and can directly connect the alarm device, which facilitates system design and monitoring for users.
5. Simple selection, no need for complex calculations
Based on twelve years of electrical design and application experience, our reliable brake unit selection method allows users to purchase the correct product without the need for complex and tedious calculations.
