AC DC Converters

The MPB125-4350RG is an AC DC converter that can be used in a variety of applications. This particular model is designed to be used in robotics, vehicle electronics, and lighting applications. It is ideal for applications that require efficient and reliable power conversion.

Applications

The MPB125-4350 RG offers a wide range of features and capabilities. It is capable of delivering up to 125 amps of onboard DC current. It has a wide input voltage range of 20 to 480VAC, and a robust system protection feature that helps protect your system from over-voltage, under-voltage, and short-circuit conditions. It is also capable of providing up to five phase-to-phase isolation options for system preferences. This converter is suitable for use in a wide range of applications, including robotic systems, vehicle electronics, and lighting.

One of the features that makes the MPB125-4350 RG ideal for use in robotics is the fact that it has adjustable output voltage and current settings. This allows for greater control of the power supply, and the ability to fine-tune the output to high levels of accuracy. For vehicle electronics, the converter has the ability to efficiently convert AC power to DC power while protecting against common conditions like over-voltage, under-voltage, and short-circuit conditions. The converter is also suitable for lighting applications, as it can deliver up to 125 amps of constant DC current with adjustable frequency settings and a wide input voltage range.

Working Principle

The MPB125-4350 RG is a full-wave, bridge-mode synchronous rectifier with reverse current protection. This converter operates by using an image transformer to step down the input voltage. The input voltage is applied to the primary side and the secondary side is connected to a thyristor bridge, which is then connected to the load. When the bridge is fed with alternating current from the input voltage, it will create a pulsating DC voltage across the load which is then converted to a constant DC voltage.

The core feature of the MPB125-4350 RG is the reverse current protection circuit. This circuit uses a sensing resistor to sense any reverse current passing through the load. The sense resistor is then used to detect any current, and if the current is more than the preset value, the converter will shut down to protect the system. This is important for applications that need to be reliable, as it prevents damage from occurring due to reverse currents.

Conclusion

The MPB125-4350RG is an AC DC converter that is suitable for robotics, vehicle electronics, and lighting applications. It has a wide input voltage range of 20 to 480VAC, and adjustable output voltage and current settings that allow for greater control of the power supply. The converter also has a robust reverse current protection circuit that will shut down the system if current is too high. This makes it an ideal choice for applications that require efficient, reliable, and safe power conversion.
