Diodes - Rectifiers - Single: FR505-AP Application Field and Working Principle

The FR505-AP rectifier series is a single-phase, high-performance and high current/voltage rectifier produced by FRX that has been widely applied in various industrial areas. It is specifically used for the purpose of rectifying electric AC signals in the range of current or voltage. This article attempts to explain the application fields of the FR505-AP and the working principle behind it.

Application Field

The FR505-AP rectifier series has a wide range of applications, from consumer electronics and manufactured products to large infrastructure projects. This device is widely employed in lighting, welding, electric motors, and frequency inverters. It is also used for rectifying AC signals for temperature control and measurement, circuit power, telecommunications equipment, and other DC power systems. It is suitable for the following industrial applications:

• Uninterruptible Power Supplies (UPS)
• Inverters
• Switch Mode Power Supplies (SMPS)
• Scanner/ Printer Circuits
• Cathodic Protection Systems
• Generator Starting-up Control Circuits

The FR505-AP rectifier is an optimal choice for the rectification of AC signals of voltage or current in the range of 0.5 - 5A. It features excellent strength under extreme temperatures, high heat-dissipation capacity and better physical stability, and can perform normally in a wide range of environments. The FR505-AP rectifier is generally used as a pre-regulator of large scale projects and/or to replace the well-known selenium rectifier.

Working Principle

The FR505-AP rectifier has three terminal connections; two of which are the anodes (positive power terminals) and the third the cathode (negative power terminal). When the AC current is connected to the rectifier, the anode connected to the positive AC power will allow current to flow from positive side to the ground whereas the other anode connected to the negative side stops current flow.

The FR505-AP rectifier has a voltage regulator to regulate the voltage entering the rectifier. This allows users to adjust the operating voltage of the rectifier. The current regulator is responsible for controlling the style of the current entering the rectifier. It ensures the rectifier will operate in steady-state conditions and also minimizes the impact of transient signals entering the unit.

The FR505-AP rectifier has a built-in temperature control system that senses when the unit is overheating and cuts off the power when the internal temperature reaches a pre-set level. This helps to prolong the lifetime of the unit and also prevents it from short-circuiting.

Conclusion

The FR505-AP, from FRX, is an ideal single-phase, high-performance and high current/voltage rectifier for AC signals and can be applied to a wide variety of applications from consumer electronics to large infrastructure projects. It offers good performance under extreme temperatures, with a built-in temperature control system to protect it from short-circuiting and over-heating. It also features voltage and current regulators to precisely adjust the working voltage or current.
