- What is an Enclosure?
We should begin! First we should discuss the fenced in area, the metal electrical control box from lyntec.com that contains every one of the electrical gadgets of the control board. Nooks are many times aluminum or treated steel and the size will shift in view of the size of the cycle.
An electrical control board walled in area can have various segments. Each segment will have an entrance entryway.
The size of the fenced in area is normally alluded to by the quantity of entryways the nook has.
Every nook will have an electrical wellbeing rating assigned by UL, the “Guarantors Laboratories” who administers electrical security.
They will likewise have an IP rating or NEMA characterization which assigns the fenced in area to be indoor or outside, waterproof or water-safe, appropriate for dangerous circumstances, dustproof, or blast confirmation.
Presently we should go inside the walled in area and discuss the non-electrical parts that make up the electrical control board.
- Back Panel, DIN Rails, Wiring Ducts
To begin with, we should discuss the back board of the nook.
The back board is a sheet of metal that is mounted within the nook that permits us to penetrate mounting openings for various gadgets which drives us to our next part, DIN rails.
A DIN rail is a metal rail with a standard width utilized for mounting electrical gadgets inside.
The following part inside the electrical control board is wiring Duct.
Conduits permit us to course the wires in a coordinated and effective manner while likewise diminishing electrical clamor between gadgets.
Then, we should get into the electrical parts of the electrical control board!
- Electrical Components of a Control Panel
3.1. Primary Circuit Breaker
The primary electrical switch is where the power comes into the control board for the entirety of the gadgets. This electrical switch by and large has a distinction outwardly of the board that permits us to stop the power.
Continuously recollect the outdoors of the electrical switch will in any case have power. The power that comes into the board can be somewhere in the range of 480 volts to as low as 120 volts.
3.2. Flood Arrester
After the power comes into the board from the primary electrical switch the power will be run into a flood arrester.
A flood arrester is a gadget that safeguards all of the electrical hardware inside the control board from electrical floods or overvoltage. An electrical flood can emerge out of a lightning strike or utility power flood.
3.3. Transformer and 24-Volt Power Supply
The power can be associated into a transformer that changes the shut down to control more modest gadgets.
In the event that the approaching power is over 120 volts, a transformer is for the most part utilized.
On the off chance that the power is 120 volts, a power supply can be utilized to step the shut down to 24 volts.
Now that the electrical control board has approaching power from the principal electrical switch and power dispersed by a transformer or power supply the various voltages can be wired into terminal blocks for considerably more directing of force all through the electrical control board.
