Cost is a critical factor to consider when selecting materials. In addition to the basic purchasing cost, there are many additional costs associated with voltage monitoring relay materials, such as the costs in inspection & testing, transport, warehousing, labor. Although the overall cost of materials makes up of so many parts, it is variable as it changes along with production volumes. Sourcing and using materials cost-effectively can be a competitive advantage, thus voltage monitoring relay manufacturers always monitor and optimize their materials expenses strictly.
