The Green Light for Blue Gold

These days, a constant 24 VDC power supply for automated applications is no longer the only demand placed on power supply units. Maximum efficiency, adequate power and current reserves – even under critical grid conditions – and protection of the load circuit with ECBs all belong to the state of the art now. And let’s not forget the comprehensive communication options offered by modern power supply systems, which make the distance between the system location and the service team nearly insignificant, as illustrated in the example below.

The distance btw the serene community of Thundorf in Lower Franconia in Germany and the bustling metropolis of Shanghai in China is a good 8,700 km as the crow flies. When Christian Müller, managing director of the engineering firm IDEAS mbH, based in Thundorf, opens a secure VPN tunnel on his computer at 1:00 p.m. and opens a dashboard, it’s already 8:00 p.m. in Shanghai. “The power supply voltage for the test unit is 23.92 V – exactly within the acceptable range”, he is pleased to report. Together with his team, Müller provided automation, electrical equipment and commissioning for the water test unit on behalf of Mösslein GmbH Wassertechnik – and did this all from Thundorf. “Because of the strict entry and travel restrictions resulting from COVID-19, it was impossible for us to commission the unit on site in Shanghai,” Müller explains. To solve this problem, he and his team needed creativity and the right selection of technical components.
