RB085BM-90TL Application Field and Working Principle

The RB085BM-90TL is an advanced rectifier module (AR) designed for use in current rectifier and sputtering systems. It is a high-performance, high-efficiency rectifier module with a switching frequency of up to 1000 kHz. The AR features a variety of features, such as stably controlling the output current, and has a wide operating temperature range of -55℃ to 90℃. The rectifier module applies to plasma etching, semiconductor and sputtering processes, as well as metal wire coating and plating.The working principle of the RB085BM-90TL is fairly simple. The rectifier module consists of three stages: rectification, inversion, and control. In the rectification stage, a power switching operation takes place in which an alternating current is converted into a direct current by using two polarization condensers in series. In the inversion stage, a high frequency power switching transformer is then used to invert the direct current back into alternating current. Finally, in the control stage, the inverter switches the AC current on a high-frequency basis, controlling and optimizing the output voltage and current.

The RB085BM-90TL is highly efficient, with a full-load efficiency of as much as 98%. The module also features load protection, allowing the module to reduce power in the event of a short-circuit. The overload protection of the module is set at 140%, while the short-circuit protection is set at 170%. The module is also very reliable, with an MTBF rating of over 60 million hours. Additionally, the module features built-in current limiting and features built-in spike suppressors, ensuring safe operation in a variety of conditions.

The RB085BM-90TL is a highly versatile rectifier module, providing high performance and efficiency while being highly reliable and cost-effective. With its advanced features and wide operating temperature range, the module is suitable for use in a number of applications, ranging from plasma etching, semiconductor and sputtering processes, to metal wire coating and plating.
