DC-DC converters are an essential component of a wide variety of devices and systems. They convert DC power from a source of varying voltage into a consistent, stable output voltage and current with low ripple and high efficiency. The TDR 2-4813SM is a specific type of DC-DC converter that provides a wide operating input voltage range from 18 to 36VDC while delivering a consistent output of 48VDC. It is a highly efficient switch-mode power supply with a wide range of applications in industrial, laboratory and residential settings. This article discusses the application field and working principle of the TDR 2-4813SM.

Application Field

The TDR 2-4813SM is designed for a variety of applications where a reliable source of 48VDC is needed. Due to its wide input voltage range, it can provide a consistent output voltage regardless of the incoming voltage at the input. This makes it ideal for use in applications where the input voltage is subject to fluctuation, such as solar panels or wind turbines. It is also commonly used in applications where space is limited, such as telecommunications equipment, computers, and energy storage systems.

The TDR 2-4813SM is also suitable for industrial applications such as motor drives, CNC machines, process automation, and factory robotics. Additionally, it can be used in residential applications such as security and surveillance systems, lighting control, and HVAC systems.

Working Principle

The TDR 2-4813SM is a switch-mode power supply, meaning a series of switches are used to convert the incoming AC or DC power to the desired output voltage. In the case of the TDR 2-4813SM, the incoming voltage is first converted from AC to DC using rectification. This voltage is then converted to a higher voltage through a boost converter, before being converted back down to 48VDC using a buck converter. This process is often referred to as “charge-pump” or “buck-boost”.

The TDR 2-4813SM is designed to provide an output voltage of 48VDC with a maximum current of 313mA. The output frequency is fixed at 16.0 kHz and the output ripple is limited to 1%. The efficiency of the converter is typically 85%. The converter is designed to operate up to 110% of the rated input voltage without affecting the output voltage.

The TDR 2-4813SM is a highly reliable and efficient DC-DC converter. Its wide input voltage range and low output ripple makes it suitable for a variety of industrial and residential applications. It is designed for easy installation and provides consistent operation over a wide temperature range.
