Why Do Wide-range Voltage Regulators Have Such A Large Price Range?

Some Wide Range Voltage Stabilizer circuits (such as basic AC voltage regulators or low-power single-phase devices) have lower procurement and production costs, resulting in relatively lower market prices. In contrast, designs for three-phase circuits, serving industrial environments, supporting high current and high power output, or integrating complex controllers and protection mechanisms increase manufacturing costs and naturally raise prices.

Different types also imply varying circuit design complexity. Switching designs, wider input voltage compatibility, higher reliability, or more stringent performance specifications place higher demands on components (such as power semiconductors, filter capacitors, and control modules), thus increasing the unit price.
