Requirements:
I require a Linear Digital Power Supply rated at 30V/10A, I am write a program in Python Language using SCPI commands.
I had shortlisted the Multi MP710086 Bench Power Supply.
Concerns:
Feedback from Supplier - Element14 regarding the Multi MP710086, Chinese technical supplier cannot confirm yet if the USB interface does indeed work with full SCPI commands.
Questions:
Any experience with this Multi MP710086 Digital PSU
Any other similar Brand/Model that fits my requirements
Any idea if can hand build a cheap Power Supply and convert it to a Digital Power Supply using SCPI Commands
That looks like a pretty good buy to be honest. Why does it have to be SCPI? That thing’s got a serial interface and is programmable. It’s probably a relatively simple communication protocol that wouldn’t take too long to reverse engineer if you really wanted to - personally I’d take it.
Else, you’re going to have to spend a lot more than $200 to get a 30V, 10A Linear supply with confirmed SCPI commands.
When it comes to bench supplies it’s: Linear, High Power, Cheap - pick any two.
Something like a Rigol DP-811 meets your tech specs - and they’re around $1,000. You’re either going to have to reign in your technical requirements, or open your wallet.
Edit: I had a look on Gumtree and eBay, no luck there on the secondhand market either. Maybe you can get lucky and find a university that’s replacing their lab supplies or something.
Good Day
I hope someone with expertise on how linear dc power supplies with SCPI interface operate can describe how to reverse engineer in parts.
Thanks
Conceptually it’s pretty easy. Hook up a logic analyzer, send it a command and see what it spits back - rinse and repeat until you’ve mapped everything out, then write a program to interpret the communication.
