Client's Request:
To design a power supply for parking meters that combined an interchangeable switching regulator with a power distribution board in a very confined space.

Overview of KLN's Contribution:
Electronic and printed circuit board design, electronic and mechanical assembly, and manufacturing of batches of 25 to 100 units each.

Detailed Outcome:
Issues that had to be dealt with included space limitations, thermal management, high current loading, avoidance of EMI and the integration of several protection circuits. They were all successfully resolved. After testing the product intensively, Park Ur Self contracted KLN to manufacture it for them.

This power supply was manufactured continuously over eight years. Batch sizes varied between 25 and 100 units, depending on our client's demand. This work involved not only electronic assembly and testing, but also screen printing of the face plate and the mechanical assembly of the latter together with the two PCBs.
