The Secret to High-Power Stabilized Power Supply Pricing

Uninterruptible Power Supplies (UPS), also known as voltage regulators, are often perceived by customers as identical in function, regardless of model, leading them to believe that all products should be the same without any distinction. Choosing a cheaper price seems like a logical choice. However, they forget the adage that "the wool is on the sheep." For customers who are knowledgeable in the field, it's not that simple. They don't just choose based on price; they compare the quality and performance of the voltage regulators to select the product that meets their needs, ensuring both affordability and quality.

1. Analyzing from the input range, there are currently two types on the market: ±15% (voltage regulators within this range are primarily produced in Fujian and Shanghai) and ±20% (voltage regulators within this range are primarily produced in Guangdong and Zhejiang). The size of the voltage regulation range directly impacts the production cost and selling price of voltage regulators.

2. Analyzing the capacity of the transformers currently available on the market: The OYHS -50KVA, when the power factor is reduced to 80%, means that the actual capacity of the voltage stabilizer reaches 40KW. Some manufacturers have set the power factor at 60%, resulting in the actual capacity of the 50KVA voltage stabilizer being reduced to 30KW. This significantly lowers the price.

3. Functionally speaking, voltage regulators on the market currently offer features such as an input master switch, output delay start, power failure self-recovery delay start, and overcurrent trip master switch. There's also a type of regulator that removes the master switch, replacing the AC contactor with an air switch, which eliminates the delay start function. Without this feature, if power is cut off during low voltage and restored during high voltage, the output voltage of this regulator would instantly exceed 500V. Most of these products originate from Zhejiang. This also results in a certain cost discrepancy among voltage regulators.
