Our company is looking for a power conversion solution to incorporate into our latest product. Our device requires 12VDC (6A maximum, 3A typical) to operate. Each of our customers will have different sources of power such as 110VAC mains and 24VAC (both ~60Hz).
We are looking for a solution which can accept at least both these voltages (ideally any voltage within that range) and still produce a solid 12VDC 6A output. Jumpers or switches are allowed in the design if required to switch between the high and low voltages, but it's important that one circuit board can accept these very different voltages.
Another very important requirement in our project is that the design be very heat efficient. Air flow is restricted, moving parts not allowed (no fans), and the device is expected to be located inside exterior aluminium containers that are exposed to direct daytime heat. Additionally the circuit board needs to be very small so that it can fit inside a box only a few inches wide, so design efficiency is highly desired instead of using heat sinks to compensate.
What would you recommend that would best solve our requirements?
Thank you in advance for your help.
