The DBLS155G RDG is a diode bridge rectifier intended for a variety of general-purpose applications. It has a maximum repetitive peak reverse voltage of 1000volts and a maximum peak forward current of 25A. It is available in DO-4, DO-8, and UL packages.

A diode bridge rectifier is a circuit configuration commonly used to convert alternating current (AC) to direct current (DC). It uses four diodes arranged in a bridge formation to direct the current through the chosen load. The diodes only allow current to flow in one direction. The DBLS155G RDG rectifier consists of four semiconductor diodes assembled in a bridge configuration, and is designed to provide a controlled output voltage from an uncontrolled AC voltage source.

In a basic rectifier circuit an AC signal is applied across the leads of the DBLS155G RDG, then each diode conducts in alternate directions, as a result of the alternative reversal of the connection of the AC signal. This alternative polarity or direction of the signal causes the diodes of the circuit to conduct in a diode action, thus allowing current conduction in just one direction. As a result, the AC signal is rectified and the output of the DBLS155G RDG is a Direct Current (DC) voltage.

The DC output voltage of the DBLS155G RDG diode bridge rectifier may be adjusted by changing the settings of the transformer connected to its input side. By using a step down transformer, the input of the bridge rectifier can be reduced, resulting in an output voltage which is less than the input AC voltage. Conversely, by raising the input voltage through the use of a step up transformer the output voltage of the bridge rectifier can be augmented.

The DBLS155G RDG is a pulsating type diode bridge rectifier. This means that the DC output voltage provided by the bridge rectifier is not a pure, smooth DC voltage but rather a pulsating, or fluctuating DC voltage. This type of bridge rectifier also creates a high ripple content in the DC output voltage. To reduce the ripple and smooth out the output voltage a filter capacitor, or group of filtering capacitors, may be placed across the output of the bridge rectifier.

The DBLS155G RDG is commonly used in rectifying AC voltage from mains power supplies into regulated DC output. This type of rectifier can be used in various industrial, consumer, commercial and scientific applications. Some examples are: Uninterruptible Power Supplies (UPS), Variable Speed Rotor drives, renewable energy systems (such as solar or wind power), and motor control, electrical welding and semiconductor processing systems.

The DBLS155G RDG is a robust, reliable, cost-effective lot-tested rectifier that lives up to its promise of providing good current and voltage ratings with minimal power dissipation. It is easy to install and long-lasting, providing a convenient, cost-effective and versatile solution for many direct current rectifying applications.
