A power supply that has a linear voltage regulator is commonly referred to as a linear power supply. The function of the power supply is quite simple: it converts varying DC voltage to create a constant, specific DC voltage. In most cases, the streamlined voltage is lower than the varying DC voltage. Basically, this serves as a sort of a limiting function, thus reducing the chances of overcurrent that could ultimately cause serious damage to the power supply. It helps in streamlining the impedance caused by excessive loads, especially if an unregulated DC power supply is used as the source. You won’t find these power supplies at your local hardware store so a little bit of research is needed if you want to order one.
Take Your Time When Researching Different Companies
In case you receive a faulty linear power supply, the damage to your appliances or machines could be severe. As a result, you have to be very careful when researching different companies that offer these supplies. Most electrical companies that offer custom services for building power supplies and transformers will assign an electrical engineer to your case who will take down specifications for the type of supply you want. You can read testimonials on the company’s website to get a better idea about how well they cater to customers’ requests.
Ordering the Supplies
Once you have done your research about different companies, the next step is to get an estimate for the power supply. Because these supplies are used in specialized applications, you will need to first get an estimate for the linear power supply before placing the order. Different companies charge different prices for their power supplies, primarily depending upon the specifications you provide and the amount of work needed to create a custom supply.
