AC DC Converters: LDA75F-5

The LDA75F-5 is an AC/DC converter designed for a broad range applications. This device is capable of providing a regulated output of 25 to 125 watts of power and features a wide input voltage range. It is intended to be used in a wide variety of applications including equipment using microprocessors, personal computers, telecom, instrumentation and medical equipment.The LDA75F-5 features a high efficiency, low noise, and low leakage current design. It is capable of operating at temperatures as low as -20 C and as high as 75 C. It is rated for an IP20 degree of protection from external contamination and environment hazards. The device is also capable of a power line surge of 7kV.The LDA75F-5 features a universal input voltage range of 90-264 Vac, making it suitable for a wide range of as input voltages around the world. It also features an active power factor correction (PFC) of 0.93, allowing it to be used in a variety of applications with stringent requirements on the power factor.The LDA75F-5 features an output power of 25 to 125 watts, adjustable from 12 to 32V at the front end, and comes in a full housing with a built in heat-sink. This device is designed to meet the EN55022 class B limits for radiated and conducted emission in the ambient noise environment, which is in line with requirements for meeting many regulatory standards.The operation of the LDA75F-5 is based on the principle of switching-mode power supply. This power supply uses a high-frequency oscillator to produce a series of pulses. The pulses cause the switching elements in the converter to switch on and off, producing a regulated output voltage.The LDA75F-5 uses a control circuit to sense the output voltage and adjust the frequency and pulse width of the oscillator to ensure the output voltage remains in regulation. It uses a sense circuit with a feedback voltage between the primary and secondary side of the transformer to regulate the output voltage.The LDA75F-5 is an ideal choice for applications requiring a reliable, high efficiency and a wide input voltage range. Its low noise and low leakage current design makes it suitable for a variety of applications. Its universal input voltage range and its PFC feature make it suitable for applications requiring a higher power factor. It is rated for an IP20 degree of protection from external contamination and environment hazards, making it suitable for use in a variety of environments.
