AC-DC converters are a type of power supply that converts alternating current (AC) into direct current (DC). The SLA4.100 application field and working principle is a unique and powerful solution for higher power applications.

It is designed for applications requiring low power factor, high efficiency, fast controls, and fanless operation. It is a self-powered AC-DC converter that provides 100A of constant current output from standard 50/60 Hz mains input. The unit has an efficiency of up to 94%, and operates from within a wide temperature range (-40 to +ё85°C) without any active cooling. It is designed to be light and compact for transportability and is resistant to extreme environmental conditions.

The SLA4.100 works by featuring a three-phase rectifier bridge, coupled with a pulse width modulated (PWM) control circuit to adjust the output current. The mains voltage is converted to a DC bus voltage, which is kept constant regardless of the load, allowing the PWM controller to maintain the output current at its preset value.

The controller offers the user various options for controlling the output current, e.g. an external signal voltage or current or a preset internal potentiometer signal. The output current can be accurately adjusted with a potential resolution of 0.1A. The device also features safety features like an overload protection, over-temperature protection, as well as active inrush current limiting to protect the unit from over-voltage and over-current conditions.

The SLA4.100 also features a built-in fanless cooling system, which ensures that the unit operates at its maximum efficiency while still providing cooling. In addition, the unit offers a user-friendly LCD display for viewing and setting the working parameters.

In short, the SLA4.100 is a versatile and powerful AC-DC converter ideal for higher power applications. By featuring a three-phase rectifier bridge combined with the PWM controller, the unit is able to maintain a constant output current regardless of the mains voltage and load. It also offers various user-friendly settings and safety features to ensure reliable operation and safe operation.
