DC-DC converters are devices that convert a fixed DC voltage into another fixed or variable DC voltage. The PAH75D48-3318/V is one such device developed by Abacus Technologies. It is designed to convert a 24Vdc nominal input voltage up to a 48Vdc nominal output voltage.

This DC-DC converter belongs to the high power category since it is rated for 75 Watts and has an efficiency of up to 94%. The unit is highly reliable due to its ripple rejection and its input to output insulation protection. Additionally, its aluminum extruded housing helps dissipate heat, making this unit ideal for applications where heat dissipation is important.

The PAH75D48-3318/V has a wide-range input voltage capability. As its name suggests, it takes a 24Vdc nominal (20.4 to 28Vdc) input but is also capable of operating with input voltages up to 50Vdc (41Vdc to 60Vdc). This allows it to be used in large variety of applications.

The output voltage of the PAH75D48-3318/V can be adjusted via a trimmer potentiometer. The output voltage range can be anywhere from 12Vdc to 48Vdc and the voltage stability is ±1% for input variations up to 2:1. This adjustable voltage feature makes the unit applicable to a large variety of applications as well.

The PAH75D48-3318/V comes with many features that make it especially suitable to different application fields. Its wide-range input power makes it an ideal choice for many transport related applications such as trains and buses, where frequent voltage variations occur often. The device also has an extended temperature range of -40 to +85°C and its full-rated output power capability up to +45°C ensures reliable operation even in the most severe environmental conditions.

The working principle of the PAH75D48-3318/V is based on the use of a flyback switch-mode power supply. When a DC voltage is applied to the unit, the internal flyback converter acts as a step-up transformer, transforming the low voltage of the input into a higher voltage at the output. This voltage is then filtered and regulated using the internal voltage control circuits, ensuring a stable output voltage.

The PAH75D48-3318/V is a highly reliable and efficient DC-DC converter that can be used in a wide variety of applications ranging from trains and buses to industrial automation and outdoor equipment. Its adjustable output voltage and wide-range input voltage make it an ideal solution for many types of applications. Additionally, its robust construction and extended temperature range make it suitable for even the toughest environmental conditions.
