The B511FSE-2T is a three-phase rectifier module manufactured by SanRex, and is designed specifically for applications where a high load current and high surge current is required. Due to its fast recovery time, excellent dynamic response characteristics, high power density, and low output harmonics, this module is particularly suitable for all types of motor-driven loads and uninterruptible power supplies.

Thyristors - SCRs - Modules

A thyristor or silicon controlled rectifier (SCR) is a three-terminal semiconductor switching device commonly used in a variety of motor control and power conversion applications. A thyristor module is an integrated package containing multiple SCRs that has been specifically designed for higher power applications. The B511FSE-2T module comprises of six thyristors, connected in a three-phase bridge configuration. The main advantage of this configuration is that each of the six thyristors receives one-third of the output current, thus reducing the power dissipation of the individual thyristors.

The B511FSE-2T module features a fast recovery time and excellent dynamic response characteristics, making it suitable for applications requiring high speed switching. The module also features highpower density, low noise, and low output harmonics. Additionally, its hermetically sealed construction ensures reliable operation even in harsh environments.

The working principle of the B511FSE-2T module is fairly straightforward. When a forward voltage across the three-phase bridge is detected, the thyristors begin to conduct current and the device turns on. Similarly, when a reverse voltage is detected, the thyristors automatically turn off. This allows the module to regulate the voltage and current levels in the circuit, and provide a number of important benefits, including improved power factor and greater efficiency.

The B511FSE-2T module is widely used in motor control, power conversion, and uninterruptible power supplies where a high load current and high surge current is required. It is also used in applications such as welding, solar cell charging, and medical equipment. The module has also been designed to meet the safety requirements of various industries and applications, and is widely used in industrial automation and electric vehicle drive systems.
