KEY FINDINGS

COVID-19 Impact: Disruptions is the Global Supply Chain Severely Affected the Availability of Raw Materials

The global COVID-19 pandemic has been unprecedented and staggering, with the DIN rail power supply market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over.

Global supply chains were hampered by the pandemic, which also affected the availability of the components and raw materials needed to produce DIN. Production and delivery of these goods were impeded by factory closures and logistical issues. Many industries also experienced slowdowns or temporary closures as a result of lockdown procedures and economic ambiguity. Due to the delay or reduction in the size of industrial automation projects, this led to a decline in the demand for rail power supplies.
