From the power supply to approval: Customised power supply for premium intercommunication system
Good power supplies perform well and work reliably. To construct such a power supply in the smallest possible space and to integrate an additional relay circuit – this was undertaken by Elektrosil.
A premium supplier for private households and commercial use required a durable power supply with a new power supply board for his innovative home intercome system. Size, power, output voltage as well as fixed positions of screw terminals and release contact were specified. A separate relay circuit for special functions was to be integrated. Finally, approvals for several countries were to be obtained. At the same time, the project was subject to the strict schedule for the market launch of the final product.
Elektrosil defined a customised procedure to meet all the client’s requirements relating to board layout, thermal management, housing samples and transformer design. The designers used components of the highest quality to achieve long life and high MTBF values. They found a suitable relay at a specialist manufacturer in Germany. The prototype and production samples were subjected to stringent testing by the customer whose quality expectations exceeded conventional power supply standards.
The Elektrosil team obtained approval of the special relay circuit for several countries, including TÜV and UL. Safety approvals were coordinated via the responsible manufacturer in the Far East. For easy further processing of the power supply units, Elektrosil worked with a supplier to implement labour-intensive packaging requests such as screw terminals screwed on by hand and their delivery in an opened state.
Since development began 20 years ago, Elektrosil has managed the product. The client regularly commissions adjustments for the product, which is sold around the world to this day.
