DC DC Converters - TDR 3-4812SM application field and working principle
The TDR 3-4812SM is a high-power DC/DC converter used in a variety of applications, such as industrial, medical, automotive, robotics, instrumentation, marine, and avionics. It is a 3-phase, 48V, 12V, 150W converter module designed to operate over a wide temperature range and in extreme environmental conditions. It is designed for high reliability and long life with a MTBF of over 500,000 hours.The TDR 3-4812SM is a full-bridge ac-dc converter. It contains a rectified transformer, a bridge filter, a low-pass filter, an active power factor correction (PFC) circuit, an over-voltage feedback circuit, and a constant current output feedback. The transformer rectifies the ac power line voltage into an unregulated dc voltage, which is then filtered by the bridge filter to remove high-frequency noise and ripple. The filtered voltage is then passed through a low-pass filter designed to remove low-frequency ripples.The voltage is then applied to a power factor correction circuit, which modifies the input waveform and eliminates high inrush currents that could damage the load. The over-voltage feedback circuit monitors the output voltage and regulates the input voltage to maintain the output voltage at the desired level. Finally, the constant current output feedback circuit maintains the output current at a constant level.The TDR 3-4812SM is designed to be used with a wide variety of loads, including batteries, capacitive loads, inductive loads, and resistive loads. It is designed to optimize power dissipation, providing high efficiency and reliable operation.The TDR 3-4812SM provides a wide range of protections to ensure safe and reliable operation, including short-circuit, over-current, and over-voltage protection. It is also designed to protect the load from external fluctuations in the line voltage. It is designed to operate in extreme environmental conditions and has a wide operating temperature range between -40℃ to +85℃.The TDR 3-4812SM is a highly reliable and efficient converter module that is designed to operate in a number of different application fields. With its wide input voltage range, high power density, over-current, over-voltage, and short-circuit protections, and wide temperature range, it is an ideal solution for powering a variety of loads in the industrial, medical, automotive, robotics, instrumentation, marine, and avionics fields.The specific data is subject to PDF, and the above content is for reference
