AC DC Converters

LS200-48 Application Field and Working Principle

An AC/DC converter, also called a power converter, is an electronic device that converts an alternating current (AC) or a combination of currents to a DC voltage or current. It is commonly used in industrial equipment, automobiles and other applications where DC power is required. The LS200-48 is an AC-DC converter that stands out as a reliable and efficient product.The LS200-48 converter is designed for high-power narrowband applications and provides a maximum continuous power of 200 Watts with a 48 V DC output. It is designed for commercial and telecommunications systems, power supplies, computer peripherals, medical equipment and other industrial applications. It is also approved by UL508, UL60950, CSA C22.2-100,IEC60950 and FCC part 15b Class B.The LS200-48 converter is designed to operate within a wide range of input voltage from 25 V to 400 V AC and a line frequency from 47 to 63 Hz. With its high output power performance, the converter offers an efficiency as high as 88% with low power dissipation. It also has built-in short-circuit, over-voltage, over-current and over-temperature protection to ensure circuitry safety and stability.The converter consists of primary circuitry, consisting of an optically isolated Pulse-Width-Modulator (PWM) and a pair of insulated gate bipolar transistors mounted in a base plate. This serves to modulate the incoming AC input and transform it into DC pulses. The secondary circuitry consists of rectifiers, filter capacitors, a voltage regulator, and additional protection circuitry for noise reduction.The primary circuit creates DC pulses for the primary and secondary stages operating in a continuous conduction mode, which prevent over-heating and over-current. The secondary circuit is responsible for converting the DC pulses into a steady DC output voltage. The voltage regulator keeps the voltage stable and is activated on the fly when the system is switched on and in response to changing loads throughout operation.LS200-48 converters are made of high-quality materials and offer a long operating life. The use of high-frequency components ensures that the energy losses are kept to a minimum. Additionally, the converter is designed to operate in ambient temperature range between -40°C and +85°C and comes with a highly efficient heat sink.In conclusion, the LS200-48 converter offers a highly efficient and reliable solution for AC-DC conversion. It is designed with protection circuitry to ensure its stability and is approved by various highly respected regulators. Its wide input voltage range and its long operating life makes it ideal for industrial and commercial applications.
