DC DC converters are electrical components designed to convert electrical energy from one form to another in order to meet the power needs of the application. A common example is the MEJ2S1509SC, a DC DC converter that is widely used in industrial automation. This article will discuss the application field and working principle of the MEJ2S1509SC.

Application Field

The MEJ2S1509SC DC DC converter is a standard device used in industrial automation, specifically for harsh environment applications such as high temperatures, high-frequency vibration, high-shock, and high-humidity environments. It is also able to provide a reliable and stable output voltage of up to 120VDC. Additionally, the MEJ2S1509SC can be used as a power supply for motor control, overcoming common problems such as pulse-width modulation (PWM) ripple and EMI interference.

In addition to its application in industrial automation, the MEJ2S1509SC is also widely used in the automotive industry. The converter has a wide working temperature range from -40°C to +105°C, making it an ideal choice for car applications. Furthermore, the MEJ2S1509SC is designed to meet automotive electrical standards such as CISPR 25 and J550 Class 2, providing a reliable source of power for automotive systems.

The MEJ2S1509SC is also suitable for use in other applications, such as LED lighting, renewable energy systems, electricity meters, and remote monitoring systems.

Working Principle

The MEJ2S1509SC DC DC converter is a flyback booster topology, which uses a single switch to convert electrical energy between different voltages. The transformer is used to increase or decrease the voltage as needed. When the switch is turned on, the transformer primary winding will be charged with electrical energy and, at the same time, electric current will flow through the load, producing an output voltage. When the switch is turned off, the transformer secondary winding will be discharged, and electric current will flow back in reverse, resulting in a negative voltage. This process will be repeated to convert the DC supply voltage to the desired output voltage.

The MEJ2S1509SC also features an over-load protection circuit to protect the device from excessive output current. When the output current exceeds the maximum rating, the protection circuit will disconnect the device, and then the device will automatically reset when the overload is removed.

In addition, the MEJ2S1509SC has a low-voltage protection circuit, which will automatically cut off the output current when the input voltage drops below the minimum voltage level. This helps to protect the device and prevent over-discharge.

Conclusion

The MEJ2S1509SC is an effective and reliable DC DC converter that is widely used in industrial automation, automotive, LED lighting, and other applications. It is a flyback booster topology and features a high-temperature working range, over-load protection, and low-voltage protection. Thus, the MEJ2S1509SC is an ideal power supply for harsh environment applications and could potentially save considerable resources in terms of energy and time.
