A power relay is an electrically operated switch that is used to control the flow of electrical current in a circuit. It consists of a coil of wire, a movable armature, and a set of contacts. When an electric current is applied to the coil, it creates a magnetic field that activates the armature, causing it to move and close the contacts. This allows the relay to control the flow of electricity to a load, such as an electric motor or a light bulb, by switching it on or off.
There are several benefits to using a power relay in electrical systems:
Isolation: A power relay allows electrical current to be switched on or off without the need for a person to physically touch the wires, providing a level of isolation between the user and the electrical circuit.
Safety: Power relays can be used to automatically disconnect power to a circuit in the event of an overload or fault, helping to prevent electrical fires and other accidents.
Control: Power relays can be used to control the flow of electrical current in a circuit, allowing for precise control over the operation of electrical devices.
Efficient: Power relays can be used to control high-power loads with a low-power signal, making them more efficient than other types of switches.
Reliability: Power relays are known for their reliability and long life, making them a popular choice in electrical systems where dependability is important.
I've been an IT consultant for most of my life and one of our mantras is -fast, good, and cheap. you never get all three!- Somehow CompSource does it. I'd ordered a portable air conditioner from two other vendors and both strung me along and finally cancelled my order *after* charging me since they apparently couldn't either manage stock or suppliers properly. I eventually got my money back but I was worried up getting gouged with summer "on season" pricing. I found CompSource had a unit almost identical (different branding) and thought I'd give it one more try. To be honest it looked too good to be true. Price with shipping was over $100 less than the competition. I was shocked that it arrived almost as fast as I got the *tracking number*. I ordered on a Friday and got the FedEx tracking number on Monday from Rich Burson and had the unit Tuesday evening. This is a nearly 100lb 12K BTU beast that I would have expected to take at least a couple weeks to get. I sent a quick thank you email and who replies? The President of the company. Personally. Smart guy. I used to check Newegg first. Not anymore. Thanks! MikeMore Reviews
