Hopefully? Another 48vdc-240vac Toriod Inverter build.

D-C2T- 500A unit is the one I use in this Inverter for peak DC input.

Select the option for 12V or 24V supply rail. Current consumption is <25mA.

Current Sensor

  Quote  Do you think it's possible to calibrate the meter without having the DSO capture facility?

You really need DSO to capture the instantaneous peaks, but you could try using a CRO and your camera to video the startup up, you should be able to catch the Peak Sensor output voltage if you set the CRO correctly.

But a DSO positive edge triggered and 100ms time base is hard to beat.

Thank you for that link.

Forgive my limited knowledge about peak detectors but what does that meter show when there is a *steady* current flowing through the hall sensor?

If it shows the value of a steady current, say 100A, then that would be accurate enough for me to deduce meter pointer positions for peak current values further up the scale.
Or am I on the wrong track here?
