Introduction: Bench Power Supply Leads With Metering!
I recently got my new bench power supply for my geeky electronics needs. I love it. I have a pair of output leads complete with those handy alligator clips.
What I really would like is metering on those leads to give me power, energy, peak amps, peak power etc.
I love knowing how much power my devices are using when I test them so created my own blend of metered leads!
Step 1: The Meter.
This meter I got off Amazon.com for 19usd. I love it so much I had purchased 3 recently. It has back lighting and a 2 row digital readout for the parameters I want. My bench supply is 10amp maximum and this meter is 50amp rated.
Step 2: Shorting Switch.
My bench supply has a constant current mode for setting the current limit. To get this mode I normally clip the black and red alligator clips together and dial the current I want.
Now with this momentary push button switch I can press and set much easier. The switch is rated 16amp so its good for my purpose. I plan to wire this switch between the output of the bench supply and the meter.
Step 3: Wiring It All Up.
Basic soldering of the meter, switch and leads. I cut both leads so I can insert the switch and meter into the output circuit.
Step 4: Adding a Little Insulation.
Using brush on electrical tape, I coated all the soldered connections. No chance now of unintentional short circuit!
Step 5: The Completed Product.
Mmm. Looking fine! Time to power it up!
Step 6: Testing!
Yay! It works perfectly. Now at a glance I can read those important electrical parameters! I'm quite happy with this project.
We have a be nice policy.
