LGA50A-5-SN

AC DC Converters are commonly used to convert an alternating current (AC) to a direct current (DC) power source. The LGA50A-5-SN is a popular AC DC Converter that combines a power factor corrected design, high efficiency scheme and state-of-the-art micro-electronics.

The LGA50A-5-SN is a single-stage, phase shift, AC DC converter that has a 5 Amp peak current. This converter works on a principle of active power factor correction (APFC) to maximize efficiency, decrease harmonic distortions, and improve the power factor significantly. This AC DC convetrer can run in two operational modes: continuous conduction and discontinuous conduction.

In continuous conduction mode, the LGA50A-5-SN takes the alternating current signal from utility and adapts it to a DC power form. It is capable of operating at line frequencies of 50 Hz to 400 Hz. The input line current contains large spikes which are removed by the active peak current control circuit of the converter. The breaker and internal Fuses protect the converter from line voltage fluctuations, current spikes or short circuits.

In discontinuous conduction mode, the input line voltage is converted to a regulated DC voltage through a fixed inductor. The current flowing through the load is clamped at a preset variable duty cycle current limit for a given range. This mode is essential for optimum power factor efficiency.

In conclusion, the LGA50A-5-SN is an efficient single-stage AC DC converter that can work in various operational modes. It is reliable power converter that is ideal for use in a wide range of applications such as industrial automation, servo motors, power supplies, medical electronics, and automotive electronics.
