SKMW20G-12

DC DC converters provide an efficient, cost-effective means to transform one voltage input level to another, enabling reliable operation and often more stringent safety standards in hazardous locations and small, difficult to access areas. The SKMW20G-12 is a high power, high efficiency DC DC converter that is specifically designed for industrial process control applications.

Features and Applications

The SKMW20G-12 offers a microprocessor-controlled, high conversion efficiency of 98% and low ripple & noise, features that are vital for industrial process control applications. In addition, this unit offers excellent transient response time, no minimum load requirement, remote output voltage sensing, user-programmable logic inputs, isolated thermal overload protection, and overvoltage and short circuit protection. The power supply has a wide input voltage range (12-75V) and adjustable output voltage from 0V to 4.25V.

The SKMW20G-12 is ideal for applications such as:

• Industrial process control systems
• Automation equipment
• Data acquisition monitoring
• Telecommunications and networking equipment
• Medical equipment
• Aviation, military applications

Working Principle

The SKMW20G-12 works by first converting the input voltage into a regulated direct current (DC) voltage of the same magnitude. This DC voltage is then regulated with a control loop, which continuously compares the output voltage with the setpoint voltage. If the two voltages differ, the control loop makes necessary changes to ensure the output voltage is maintained at the same level as the setpoint.

The unit consists of three main parts: a voltage regulator, an audio filter, and a current regulator. The voltage regulator is responsible for controlling the output voltage, by adjusting the supply current. The audio filter, which is a low pass filter, helps to reduce the noise and is used for communication and other applications. The current regulator makes sure the output current stays within the set specifications, avoiding any load related instabilities.

Conclusion

The SKMW20G-12 is an excellent choice for applications in which a reliable, high efficiency DC DC converter is required. Its high power, wide input voltage range, adjustable output voltage, and other features make it ideal for industrial process control systems, automation and data acquisition monitoring, telecommunications, and medical equipment, among others. Its microprocessor-controlled, high conversion efficiency of 98%, low ripple & noise, and excellent transient response time make it an ideal choice for more stringent safety standards in hazardous locations and small, difficult to access areas.
