The B652-2T is a four-phase thyristor module class 2. It is mainly used for power control applications and can be employed in a number of different scenarios including motor and speed control, frequency conversion, rectification and power factor control. The main feature of the B652-2T is its high current rating of up to 3500A. Additionally the B652-2T is capable of blocking voltage ratings up to 800V and has an on-state voltage drop of just 0.8V at its full current rating of 350A.

At the heart of the B652-2T module class 2 are four thyristors. Each thyristor acts as a switch element and consists of three junction regions. An anode and a cathode form one of the junctions while the third junction is the gate. The anode and the cathode are connected in series to a DC (direct current) power supply, while the gate is connected to a control circuit. When the gate is energized, the thyristor-switches on, allowing current to flow through the device.

When the gate voltage is at 0V, and no current passes through the gate, the thyristor is said to be in the off state and the current flow through the device is halted. This means that when the control voltage is turned off, the circuit is prevented from conducting current and the thyristor will remain off until the control circuit is again energized. This is known as the ‘latching’ property of the thyristor and is the reason that thyristors are also known as semiconductor relays.

In order to ensure that the thyristors are not damaged by excessive current, the B652-2T module class 2 has overcurrent protection. This protection is provided by a Transient Voltage Suppressor (TVS) diode that is connected between the anode and the cathode of each thyristor. This diode senses a potential increase in voltage and if the abnormally high voltage is maintained, the diode will activate and block the passage of current, thus preventing damage to the thyristor.

In addition to providing excellent protection from overcurrent, the B652-2T module class 2 also offers insulation protection. The thyristors are housed in an enclosure which has a high dielectric strength of 5000V between terminals. This helps to provide protection from short circuits and other electrical hazards. Furthermore the B652-2T module class 2 has a built-in Overvoltage crowbar circuit which can protect the module from extreme voltage surges.

The B652-2T module class 2 is an efficient and reliable device for power control applications. It combines excellent protection from overcurrent, insulation protection and overvoltage protection, making it well suited for a variety of applications. The B652-2T module class 2 is a reliable and cost effective solution for power control needs.
