Simply distinguish the quality of voltage regulator

Many buyers suffer from a lack of professional knowledge when selecting suppliers, and are confused about voltage regulators. They do not know which supplier's price is artificially high, which one is worth it, and which one is of low price and inferior quality? Here, the editor will teach you some simple and practical methods to distinguish:

Method 1: The smaller the open circuit loss and short circuit loss of the voltage regulator, the better its quality, the lower the temperature rise during operation, and the better the load rate.（Prevent aluminum from replacing copper.

Method 2: Use a voltage regulator for debugging, or personally inspect at the manufacturer's production site, continuously increasing and decreasing the input voltage. Use a multimeter to test the output voltage. If the output voltage accuracy is high and stable, it indicates good quality. Otherwise, it should not be selected.

Method 3: Observing details, the cause of voltage regulator failure is mostly due to manufacturers stealing work and saving materials. Mainly the brand of air switches; Poor quality and safety switches can save a lot of costs; Is there any installation of casters? Four casters can save a lot of material and labor costs; Qualified voltage regulator assembly screws should be made of stainless steel.

Method 4: Written agreement. Generally, manufacturers who trust the quality of their products will proactively include it in their purchase and sales contracts.

Method 5: Understand the market reputation of the manufacturer and take a look at the feedback from previous customers about the product. The manufacturer claims to be good a thousand times, it's better for the customer to say the manufacturer is good once.
