Solid State Power Switching devices are underappreciated in the arena of temperature control panels. Yet, the fact that they are overlooked cannot create doubts about their usefulness and need in the operations.
Solid-state switching devices are semiconductors that control the power, either voltage or current, supplied to the production system. While their job is primarily to switch the power on and off at a rapid pace according to the controller’s instructions, they can do multiple standalone functions that primarily include diagnostic and supervisory functions.
They can be seen in a similar light to electronic circuit breakers because of their ability to protect the system from damage caused by unchecked temperature settings or power supplies. Their reliability and ability to easily manage fast-paced switching operations increase their functionality and demand in the market.
They are best utilized in low-noise areas and in areas that are switched frequently, for example to control resistive loads, conveyor systems, etc. Their compact design makes them a viable choice for use in control cabinets, allowing for greater space availability.
Solid-state switching devices are easy to integrate into feeders of load. This is largely down to their industrial design and connection method. Yet, some aspects need to be taken care of when these devices are installed. The ambient conditions and the environment where they are being installed determine the switching devices’ performance.
Each version of these switches has a few restrictions that need to be followed down to the letter t. For example, there will usually be a manual attached that will outline the minimum spacing and solid heat relays and the heat sink where these devices are to be used. If these are not taken care of, the functionality and effectiveness of the device will be affected.
Despite being rugged and reliable in their construction, solid-state switching devices exhibit a greater sensitivity in the event of a short circuit. Hence, precautions must be taken to protect it against damage.
