DC DC Converters

DC-DC Converters (or DC-DC transformers) are electronic power supply conversion devices used to convert an unregulated direct current (DC) input voltage to a regulated DC output voltage. The output from these converters can be either a low or high voltage, depending on the input and conversion type. They are commonly used in a wide variety of applications, from mobile phones and consumer electronics to medical equipment and industrial automation.

The EQW012A0A-S is a DC-DC converter from the EQW012A series of DC-DC converters developed by Eltek. This series of converters utilizes the SLIC technology to convert the direct current from a wall outlet to the regulated DC voltage needed for a specific application.

Application Field

The EQW012A0A-S is a mid-size DC-DC converter designed to be used in a variety of applications including industrial automation, data centers, and telecommunications. It is suitable for a wide range of input voltages, from 10 to 14V, and is capable of delivering up to 500 watts of output power. The low power consumption of the converter make it ideal for applications where power consumption is a primary concern.

The compact size of the converter allows it to be used in space-constrained systems, such as laptops and embedded systems. Additionally, the EQW012A0A-S is designed to withstand harsh environmental conditions, making it suitable for use in high-temperature and hazardous environments.

Working Principle

The EQW012A0A-S utilizes the Switch Mode Power Supply (SMPS) Technology to convert the direct current from a wall outlet to the regulated DC output voltage. The SMPS technology works on the principle of rectification and switching. The AC voltage from the wall outlet is first rectified, resulting in a direct current. This direct current is then switched on and off at high speed, resulting in the desired output voltage.

To ensure high efficiency and load regulation of the DC output, the EQW012A0A-S is equipped with an Automatic Voltage Regulation (AVR) technology. The AVR technology works on the principle of pulse modulation, providing precise control of the output voltage. This ensures that the DC output voltage remains constant and within specified limits, even with varying input and load conditions.

In addition, the EQW012A0A-S incorporates several safety features such as over-voltage and over-current protection, as well as active current limiting. These safety features help protect the equipment from damage due to overloads and short circuits.

Conclusion

The EQW012A0A-S is a versatile DC-DC converter from the EQW012A series of DC-DC converters developed by Eltek. It is suitable for use in a wide variety of applications, offering high efficiency, low power consumption, and high-performance output voltage regulation. It is also equipped with several safety features that help protect the equipment from damage due to overloads and short circuits. Therefore, the EQW012A0A-S is an ideal choice for those requiring an efficient and reliable DC-DC converter.
