Power Supply for bench testing and wiring

Hello, I am starting to work on my power bus and electronics cabling. Is the QW-MS3010D adjustable power supply adequate for the job for bench testing? 0-30 Volts 0-10 Amps.

I am planning on a 12 volt system, all glass, dual alternator, possibly dual battery. 10 Amps will not supply the entire panel, but will it suffice for most bench testing? Is the power quality good enough for the new electronics?

Thank You.
 
Personally, I think its a little overkill. But, if having the led display and a more finished looking product is worth the $99, go for it.

Any properly regulated 12vdc, 10 to 15 amp power supply will do the job. The big thing is to insure you've got the polarity hooked up correctly and that you have circuit protection for the equipment under test, whether it built into the power supply, or you add an inline fuse.

This is very similar in price and specs to my bench powersupply:

I use something very similar to this power supply and have found it more than adequate. I?ve also used it to power my avionics so I can practice with my EFIS, gps, etc so that I know how to properly use the equipment.

I am using something similar as I prepare my avionics. One nice thing about this scope is that it gives you the current draw amount so you can easily size your circuit breaker or fuse requirement.
 
I used one like this: https://www.dxengineering.com/parts/alo-dm-30tr

Similar to others described, amps feature is nice, also when the power is off it will show voltage so you have an idea how much your battery is supplying if you connect it that way. When doing avionics testing I just made extension cables from the power supply to the battery leads with insulated covers (something simple like silicone tape):

Power Supply Suggesttion

Thank You everyone.

I can pick the power supply up for 40 dollars. Still twice as much as the one mentioned in post#2 but I think the variable voltage will come in handy on my "other' projects around the hanger and home.

Thank You.
