DEVELOPING A FLEXIBLE POWER SUPPLY
When one of Ideal Power’s customers had precise requirements for a power supply, the company was able to take an established product that met most of the requirements and adapt it to suit the project
A
technology design innovator in the irrigation industry was developing a new system to water crops, control the environmental temperature and humidity levels, and the amount of water that specific crops need to flourish in a factory greenhouse. To achieve best performance, the power supply
needed to be able to support this would need to run from a mains that gives out power from 20W – 40W with an output of 5-12V DC and an output current of 1-2A. The Power supply would need to comply with the latest standards EN 61000-3-2, EN-61000-3-3, EN 55032, EN 55024 and must comply with CE, EMC,Reach,RoHS standards in order to be used for the European and US Market. The main challenge that the designer was facing
was finding a product where the plug and power jack must be IP67 sealed for waterproofing and locked in, to avoid the plug from being accidently unplugged as the product will be used around liquids. The other challenge was finding an application that meets UL94 V-0 flammability standard in case of accidental fires, this was important as the device will be used in hot temperatures, so the designer needed a strong material to cope with; in case of a fire hazard occurring.
The last challenge the designer faced was that the product is going to be used across Europe and the US, meaning that the wall plugs and approvals must be compatible to achieve this. Ideal Powers 59RKPO-EU1202000CD-5 met most of the customers requirements, as it met the latest approvals and safety certifications for both the European and US market.
The designers original request was a product that achieves IP67 waterproofing rating, the product on offer was able to go one better as it meets IP68 water proofing rating.
Although the original product recommended by Ideal Power met some of the customers requirements, Where the original product came unstuck was that the product did not meet the original requirements for the flammability standard UL94 V-0 and did not offer the relevant wall plugs that the customer required. As a result, Ideal Power worked closely with the
customer utilizing the modularity of the 59RKPO platform and were able to design a bespoke product that meant the material used for the power supply met the flammability standard UL94 V-0 and the wall plugs were designed so that the customer could use both the EU and US plug on the same device.

Given, Ideal Powers customisation ability and exceptional applications support, the customer was able to incorporate highly tailored features easily, leading to a fast time to market and reduced development costs. The 59RKPO-EU1202000CD-5 gave the power system the level of performance required while meeting budget expectations. The solution offered high reliability and a history of strong performance leading to a lower cost of ownership at the system level. Despite the heavy industrial operating environment, the customised materials for the product helps to achieve long product life. The product meets the requirements of future 62368-1, ensuring no major investments will be needed to reassess the application when the new standard comes into effect in late 2020. Ideal Power can offer designers and engineers bespoke services to achieve any Industrial project, ensuring the application meets the latest safety & certificate approvals. They can customise any product, thereby enabling a fast time to market, huge savings on engineering, qualification and certification costs.
