DC DC Converters

DC-DC converters, also known as switching converters, are power electronic circuits that provide step-down, step-up, inverting, and voltage and current regulation in various applications. The TEL 10-4813WI is a DC DC converter designed for power supplies for electronic systems, such as ATM machines, POS terminals, routers, and switches.

The TEL 10-4813WI series is a 40W highly efficient, reliable DC-DC converter that supports input voltages of 400 VDC or 230 VDC with output adjustable from 1.5 to 12 VDC. It is housed in a shielded metal housing that has a built-in cooling fan which offers a high power density thanks to its superior cooling performance. The wide input range ensures compatibility with various types of power supplies. The built-in protection circuit also prevents damages from external interferences, such as lightning strikes.

The TEL 10-4813WI series is typically used in applications where working efficiency or power density must be prioritized. Additionally, the ceramic insulation package of TEL 10-4813WI ensures superior insulation performance as well as a long life expectancy. It therefore offers a great choice for system designers looking for a reliable and flexible power supply.

The working principle of the TEL 10-4813WI is based on a boost converter. It operates by taking dc input power and converting it to a dc output voltage that is greater than the input. This is done through a series of fast and efficient switching devices which provide boost to the input voltage. The output voltage is regulated by controlling the on and off states of the switches. The switching frequency of the TEL 10-4813WI converter is in the range of 900 kHz to 2 MHz and the switching devices use a pulse width modulation technique for better power efficiency.

The TEL 10-4813WI can also be used in various other applications, such as for12V battery charging, as a buck converter to step down the output voltage, as an inverting DC-DC converter for converting AC power to DC, or as a boost converter to increase the output voltage. The TEL 10-4813WI is also ideal for LED lighting applications, digital displays, and switching power supplies.

In summary, the TEL 10-4813WI is a highly efficient DC DC converter designed for a variety of applications, from LED lighting to power supplies for electronic systems. It operates through a boost converter principle based on fast and efficient switching devices and controlled by a pulse width modulation technique. Highly efficient and reliable, the TEL 10-4813WI is a great choice for system designers who need a flexible and reliable power supply.
