PCB design: high current en voltage monitor
Budget: $250 – $750 USD
I am looking for an experienced HIGH POWER PCB designer who can create a high current and voltage monitor for a range of 48v to 120v DC and 5a to 200a.
The ideal candidate will have experience in designing PCBs for high power applications and will be able to incorporate overload protection into the design and use of hall sensors on high current. Additionally, the monitor should have the ability to log data for analysis.
For monitoring we will use ESP32 S3 WiFi on board. The pcb have 3x DC input ports, and have 3x DC output ports.
INPUT-1:
This port can have 120v 10000w power. This input-1 can be forwarded to OUTPUT-1, OUTPUT-2 or OUTPUT-3. That means this port will have 3 relais switches. This port can only forwarded to one output port. Forward to which port depends on the current en voltage level.
INPUT-2:
This port can have 48v 20000w power. This input-2 can be forwarded only to OUTPUT-1. That means this port will have 1 relais switch. Forward depends on the current en voltage level.
INPUT-3:
This port can have 120v 10000w power. This input-3 can be forwarded only to OUTPUT-1. That means this port will have 1 relais switch. Forward depends on the current en voltage level.
OUTPUT-1:
All forwarded power will be reduced to 48v 3500w
OUTPUT-2:
Will not have any reduction and power will be forwarded straight forward.
OUTPUT-3:
All forwarded power will be reduced to 54,6v 5a
