VSUU-120-48 Application Field and Working Principle

Introduction

The VSUU-120-48 is a DC/DC power converter designed for reliable supplies for single phase and three phase mobile welfare generators. The converter allows the output voltage to be adjustable between 24V to 48V. It is capable of receiving input power from both 120V and 240V AC sources.

Application Field

The VSUU-120-48 is designed to be used in multiple applications including industrial, emergency backup, medical, and commercial. Mobile welfare generators are the primary area where this converter is most applicable.The VSUU-120-48 is ideal for mobile welfare generators because its adjustable output voltage means it can be used to provide power for various devices that require different power selections. Additionally, it is also designed to be used in hazardous locations. The VSUU-120-48 is also designed with an IP66 rating for industrial and emergency use.

Working Principle

The VSUU-120-48 DC/DC power converter works under a simple principle. The input power is received by the converter from the AC source, from either a 120V or 240V source. This input power is then converted into a DC power output which is adjustable between 24V and 48V. This is done utilizing a full-wave bridge rectifier, which converts the alternating current to a direct current.The converter then utilizes a step-down transformer to reduce the voltage and a linear voltage regulator to further control the output voltage. Finally, the output is then filtered with an LC filter to reduce any potential noise or distortion. This provides a reliable and rugged power source for mobile welfare generators and other devices.

Conclusion

The VSUU-120-48 DC/DC power converter is a reliable and rugged power supply device that can be used in a variety of settings and applications. It is perfect for mobile welfare generators, providing adjustable output voltage from 24V to 48V. The converter utilizes a full-wave bridge rectifier, a step-down transformer, a linear voltage regulator, and an LC filter to provide a reliable and noise-free power output.
