$15-25 USD / hour

Please only apply if you understand the requirements. Generic intros and questions will be ignored. You will likely be selected if you show that you read the project description. One way to do so is to write a quick overview of how you would design this PCB and which parts are critical, in your opinion. We are looking for someone who can: - Pick parts - Design a PCB - Have it manufactured - Maybe: test it Bonus: Write a firmware, or I will write one myself You will design a power management box for telecom applications. Design voltage is +/-48V 16x 20A battery inputs 16x 6A load outputs 8x mid-span PoE injectors (passive 2-pair/4-pair 48V) 2x 100A inverter/charger interfaces 2x 20A Aux in/out Remote load control using IP over Ethernet and Wi-Fi Soft & Hard fuses on all outputs Bidirectional power monitoring for every power input/output Joule counting (this could be done using an external system like a Victron BMV) The design must be reasonably compact, so a stacked PCB design will likely be needed. Attached is a picture of a box we designed for this function.

Hey, it Sounds like I could be a fit here. I have successfully completed a tonne of power management projects for both businesses and private clients. I know it can be challenging (and time-consuming!)to -Selecting proper circuits and subsystems -Selecting the right design approach and set rules -Route critical tracks -Select the right manufacturers -and produce an excellent end product… Most of my clients tell me that they are looking for someone who takes work off their shoulder The simple solution: LET ME HANDLE IT, I intentionally target a smaller niche of projects with which I can work closely, so we get the exact results you’re looking for without struggling through every step. If you're searching for a committed, deadline-driven freelancer to take the burden of this project off your shoulders and collaborate with you to get the job done well, let's talk! Here are a few examples of the results my clients got in the past : -NINA TAUCHER, A German Entrepreneur, got her idea into a product in 3 months -ALI HAMDAN, A Turkish Entrepreneur, got his MedTech product in 2 months. -SYNTBIT, A German Engineering Company, Got optimization in the existing product in 15 days -AUGRADE, A startup from India, resolved critical design issues in 4 weeks. Why don’t we hop on a quick call and talk about what you’re looking for? with a few minutes of chat, I should be able to get you an answer as to whether we fit. Looking forward to working with you Abbas JawadWala

Hello, sir. The important thing in designing this device is to select a current divider and MCU that can withstand high current. First of all, create a current distribution diagram and proceed with the schematic and PCB layout design based on it. I consider the DC/DC converter to be a very important component in designing a DC power management device. I think I am the candidate developer that you find. I am good at PCB design and embedded firmware programming too. So can help you. Hope to more discuss this with you.

See you need a DC/DC power engineer, looks like a battery charger, I have even built a Joule Counter this was many years ago, it was so we can monitor the SoH and SoC of the battery. There are several design considerations here, once its modular base, where we can use a Generic RPI or similar boards (I can write code) and plug into the DC/DC board, these boards are just signal control and used to receive feedback. I can have it mfg. if you like and ship it (TESTED) to you, if you need some kind of certification I have contacts to do that with the companies directly. Let me know if you like to discuss further on this, I have done power supply and control design for more than 20 years. My primary form of communication is English.

Hello, how are you, I have experience in the design of power and measurement modules. I read the description and I can - Pick up details - Design a printed circuit board, including a multilayer one - Order production, choose a factory of your choice, calculate the logistics of components, I have the opportunity to check the device Depending on the selected controller, I can write the firmware. More details are needed to understand what marginal voltages are possible in the device, Is it really 96 volts or is it for measuring in both directions. Given the need for monitoring, we can programmatically calculate the amount of energy in joules, knowing the time, voltage and current. And no need to fence separate joule counts.
