Rotary potentiometers and rheostats, when used in telecommunications systems, have applications of varying complexity, depending on the type and type of component being used. The Model 3549S-2AA-103/103B is a potentiometer and rheostat combination designed as a current regulator. It features a mechanical switch mechanism, a mechanism for adjusting resistor values, and an accurate and versatile control output. This article will discuss the application field and operating principle of the 3549S-2AA-103/103B.

Overview

The 3549S-2AA-103/103B potentiometer and rheostat combination is a two-pole, multi-section variable resistor. It is designed for controlling the amount of current that flows in a network of telecommunications systems. The 3549S-2AA-103/103B can be used with either AC or DC power and is suitable for both low and high voltages. It is designed for use in PCM (Pulse Code Modulation) systems, digital switching systems, and PMS (Permanent Magnet Synchronous) systems.

Application Field

The primary application of the 3549S-2AA-103/103B is as a regulator of current in telecommunications systems. It is designed for use in a variety of systems, including PCM (Pulse Code Modulation), digital switching systems, and PMS (Permanent Magnet Synchronous) systems. It is also used for controlling the amount of current that flows between two branches in a longhaul network. The 3549S-2AA-103/103B is used mostly in multi-pole systems, particularly multi-pole systems that require an accurate regulation of current.

Working Principle

The manner in which the 3549S-2AA-103/103B operates can be broken down into two major parts. First, it provides a mechanical switch mechanism which allows the user to select the relative amount of current to pass between two poles, depending on the setting. Secondly, it contains a mechanism to adjust the resistances of the resistor elements captured through the mechanical switch mechanism. This allows the user to change the overall resistance of the two-pole network as desired.

The 3549S-2AA-103/103B utilizes a multi-section variable resistor which is used to control the amount of current passing through the two poles. The variable resistor consists of two sections; one for the current and another for the voltage. The current flowing through the two poles is regulated by means of adjusting the resistance of the resistance elements using the mechanical switch. The result is an accurate regulation of the current passing through each pole.

Conclusion

The 3549S-2AA-103/103B is a potentiometer and rheostat combination that is used in telecommunications systems for controlling the amount of current passing through two poles. It has a mechanical switch mechanism for adjusting the resistance of the resistor elements and a two-pole, multi-section variable resistor that allows for accurate regulation of current. Finally, it is designed for use in PCM, digital switching, and PMS systems.
