Can someone please convert this 1 page ORCAD schematic to Altium.
The version of Altium I'm using (14) seems to only import older versions of ORCAD
Orcad file can be found here: https://www66.zippyshare.com/v/afPlBbSx/file.html
Much appreciated
This is a AC transfer relay circuit that transfers from 120V MAINS to battery backed 120V inverter when the MAINS fail.
Load is 0.25A
Relay is EE2-24NU surface mount rated 2A, 240Vac (24Vdc coil).
TVS is to protect the capacitor.
Why not just use an ac relay? 3x cost, larger and no SMT.
Do...
Software is not my strong point so I'm looking for advice.
Option 1) On the Microchip website, it appears they offer a free IDE and compiler for the SAM MCU https://www.microchip.com/development-tools
Option 2) On the Microchip website, it appears they offer a SAM-ICE debugger for $150...
I'm working on a project and for proof of concept I used a Cortex M0 based Arduino board (MkrZero) for the micro controller portion. I have some limited experience with C and wrote the firmware using the Arduino IDE. Now that its all working I would like to move away from the speed limitations...
Version 13, I'm not sure what I did to break this?
My component libraries have supplier links to for example Digi-Key and until today, when I selected a component in the SCH Library list, the information from Digi-Key would be displayed in the pane directly below the SCH Library pane. The pane...
I realize a 2 layer board is less than ideal for this, however that's what were stuck with for this application.
I'm laying out a board that will make use of an open source Arduino board for the uC section, because the code is already written and tested on the MkrZero board. I imported the PCB...
This quirk seems to happen once in a while, and I'm not sure what the cause is or how to fix it?
Board origin is set to 0, 0, while organizing the component placement I can no longer move the cursor left of the origin, actually I can but just slightly to -214mils. I would like to be able to...
I'm going to keep looking for a suitable power transformer, everything I have found so far with high output current capability (10A) is well over 10VA, most of them 150VA, which is too large for the space I have available.
I will try a regular power transformer, I should have a 120:24 in my transformer box.

Tha audio amplifier is configured as a current amplifier, amp -> CT -> current sense resistor -> Gnd. The voltage at the CSR provides feedback to the amplifier. This seems to work...
Magnetics is definitely a weak point for me, I need some help, hopefully someone with expertise can offer some guidance.
I'm using an audio amplifier configured as a current source for some testing I'm doing. It works well, however this amplifier is limited to about 3Arms @20V. I would like to...
All good points, thank you.
If I build it I will use 15V rails for some headroom for 1kV
The simple voltage divider is worth a try, eliminates bias and offset errors.
I think I will layout both and send in with next PCB order and then compare.
Suggestions for capacitors for R3, R4?
I have...
I was working on a circuit the other day that measures ac/dc voltage up to 1kV. The input impedance of the circuit is ~2MΩ , so simply connecting any of my DMM's (10MΩ input impedance) loads the circuit considerably. I do have a 34401A DMM that has a GΩ input mode however this high impedance...
