When it comes to garage door operators, we have your best interest in mind with reliable products to choose from. There are two common types of motors used in most GDOs and it’s important to understand the difference when you’re looking to purchase a new garage door opener. The difference between AC and DC operators is the type of motor used in them. While an alternating current (AC) goes back and forth between the power source, a direct current (DC) moves in one constant direction. Like many products on the market, there are advantages in purchasing one model over another whether it be price, simplicity or function. AC motors are very simple to power straight from a wall outlet. This makes AC-powered operators easy and inexpensive to use in an application. Check out our line of AC Garage Door Operators below.
