Why Are Industrial Wide-range Voltage Regulators Generally Priced Higher Than General-purpose Avr Modules?

Industrial brand wide range stabilizer for ac devices typically cover a wider input voltage range, adapting to more complex power supply conditions and extreme operating environments. These devices are designed with durability and long-term lifespan considerations for harsh industrial environments, such as the ability to operate stably within ±20% or even wider voltage fluctuation ranges, which is difficult for many standard AVR modules to achieve.
