    We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting certain options...

    Using Altium designer, Design a simple PCB to be able to connect an oscilloscope to a high voltage cables with protections see drawing. Voltage: Phase to phase RMS voltage is 750VAC at 50 to 70Hz or 1200VDC depending on the device where we will connect. Transient at in the 3kV range, with 1MHz frequency. This is what we want to record. So each trace will need to be spaced accordingly. Current: The wire we will use is a AWG18, however we can have fuse holder with fuse down to 2A for the track width. The probe I’m using have only micro-grabber tip, so ideally I would like to connect on some kind of test point, as shown below. So in the drawing in attachment, the plan was to install the PCB board inside a plastic box, have my cable that are connected on the top. I was thinking of...

    I have a Project at hand which requires a BLDC motor to be RPM controlled. Basically, the shaft has to rotate at a constant RPM with varying loads. I’ll give more details to the selected freelancer. So basically, the tasks to be done are: 1. Selection of Motor from online websites based on my requirements. 2. Selection of Motor controller from online websites or design one. 3. Design/coding of a Arduino based PID controller or be combined with the motor controller. 4. An AC to DC circuit design for powering the motor or selecting some readymade stuff. I am not an Electrical Engineer so I might not be able to give much technical details.

    Hi, I would like to install PV system with the battery storage. My power usage is quite high, so would like the system with the strongest possible panels, on the budget. Have two sunlight tunnels on the top roof which will limit panels space. Lower part of the roof is shaded, so would ideally need micro-inverters on that part. Not sure if is possible combination of micro-inverters and string inverter, maybe with optimizers?
