The SPW481 is a power module with an input voltage of 100-120V.

A power module is an independent power supply device that supplies power to other devices.

According to the different hardware structure, PLC can be divided into integral, modular and hybrid. Among them, modular PLC adopts a modular structure and can be combined by users on demand, which has the advantage of strong scalability.

The power module provides the following functions:

Isolation: SPW481 safety isolation, noise isolation, ground loop elimination.

Protection: short circuit protection, over voltage protection, under voltage protection, over current protection, other protection.

Voltage conversion: SPW481 boost conversion, buck conversion, AC/DC conversion, polarity conversion.

Voltage regulator: SPW481 AC mains power supply Remote DC power supply, distributed power supply system battery power supply.

Noise reduction: active filter.

SPW481 power module is a power conversion device that can be directly welded to the circuit board, its main role is to convert alternating current and direct current to each other, according to the conversion mode is generally divided into AC-DC and DC-DC two modes. It can power ASics, digital signal processors, microprocessors, memory, field programmable gate arrays, and other digital or analog loads.

A complete power module is generally composed of input rectifier filter, single-chip switching power supply, high-frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts, SPW481 by these components of the power module not only simple design, small space, but also has high reliability and high stability and other characteristics. In many industries favored by users, especially in the exchange access equipment, mobile communications, microwave and other communication fields and automotive electronics, aerospace and other industries are widely used.
