Diodes - Bridge Rectifiers are devices which convert alternating electrical current (AC) to direct current (DC). The 2KBP04M-E4/45 bridge rectifier is a 4-terminal device with a maximum forward direct current (IF(AV)) of 4 A and a reverse voltage of 100 V. It can handle peak surge currents up to 30 A.

This 4-terminal bridge rectifier is used in AC-DC power supplies, DC-DC converters, battery charges, and rectification of variable-frequency motor drives. It is used in power supplies and other applications that require rectification from AC to DC.

2KBP04M-E4/45 bridge rectifier is designed to deliver high reliability, high efficiency, and a long life. It has a low thermal resistance, which means it will dissipate heat faster and maintain a stable temperature during its operation. The device also has a low voltage drop for increased efficiency.

The 2KBP04M-E4/45 bridge rectifier has its own internal circuit protection, which helps to protect the device against excessive current, temperature and voltage conditions. The device can also be used with either line or downstream protection devices, like a fuse or a circuit-breaker.

The operation of the bridge rectifier is fairly simple. An AC voltage is applied across the two AC terminals of the device. The alternating current flows through diodes which are connected in a “bridge” configuration and then flows out of the positive and negative terminals as DC.

The diode bridge rectifier has four diodes connected in a full-wave bridge configuration. Two of the diodes, D1 and D2, are connected in series with the AC source and two, D3 and D4 are connected in series with the output, at the positive and negative terminals. This configuration allows the rectifier to conduct electrons from the anode to the cathode and then from the cathode back to the anode during each AC cycle. This results in a full-wave rectified output from the two output terminals.

The diodes D1 and D2 let current flow to the DC output when the AC voltage is above a certain threshold voltage. When the AC voltage is below this threshold, the diode will not let current flow to the output. This is called the cutoff voltage, and it limits the voltage that can be put across the DC output.

The 2KBP04M-E4/45 bridge rectifier also has an advanced current monitoring system. This system measures the AC input current and the DC output current, and if the output current rises above the rated level, a circuit protection will be activated and the power will be automatically shut off. This protection helps to protect the device from overheating and overloads.

In conclusion, the 2KBP04M-E4/45 bridge rectifier is a reliable, efficient, and long lasting device, suitable for many applications. It has a low thermal resistance, low voltage drop, and internal circuit protection. It is used in AC-DC power supplies, DC-DC converters, battery chargers, and rectification of variable-frequency motor drives. It can handle peak surge currents up to 30 A and its operation is based on four diodes connected in a full-wave bridge configuration.
