Product Description:
The 8B0W0079H000.001-1 is a compact, high-performance braking resistor manufactured by B & R Automation. It is suited for ACOPOSmulti power supply modules, providing effective energy dissipation during braking and deceleration. This resistor has a continuous power rating of 632 W when mounted horizontally and a rating of 701 W when mounted vertically. The enhanced capacity when in vertical orientation is because heat rises more effectively in the vertical position, enhancing the passive cooling process. The module is designed to operate with a maximum operating voltage of 850 VDC, making it suitable for high-voltage industrial applications.
This braking resistor has an ohmic resistance of 33 ? ~10%, ensuring efficient dissipation of electrical energy during braking operations. The tolerance of ~10% ensures flexibility in resistance and allows for safe operation across different load conditions. The unit comes equipped with a shield connection that utilizes a high-strength cable gland. This helps to protect the resistor and surrounding equipment from electromagnetic interference (EMI), ensuring reliable and stable performance. The high-strength cable gland provides a secure and durable connection, ensuring that the shielding remains intact even in harsh operating conditions.
The resistor is rated IP65 according to the EN 60529 standards, meaning that it is resistant to dust and water jets. This high level of protection ensures that the braking resistor can operate reliably in harsh industrial environments where the system is exposed to dust, dirt, and moisture. The unit boasts a wide operational temperature range of -40 to 90 degrees C. This allows use in demanding industrial settings including outdoor applications. The unit is designed for wall mounting and can be installed in a vertical or horizontal orientation to match specific space and application requirements.
