Velleman AIM6030A 30A DC Panel Meter
Velleman AIM6030A 30A DC Panel Meter is rated 4.0 out of 5 by 5.
Rated 5 out of 5 by from very good invintoryThe products that you sell are a very high quality and the service is great! If ever I need electronic parts I always check with your company first. And most of the time I don't need to look any further. Thanks for being there. It's nice to know that you can still buy in America and get parts FAST!

Rated 4 out of 5 by from Velleman AIM6030A 30A DC Panel Meter: Nice little meterThe Velleman AIM6030A 30A DC Panel Meter is a nice little meter for the price. It is surprisingly accurate with a decent response time for changing currents. The only complaint I had about it was the fact that the cover bezel was off of the meter face and the scale plate bent slightly forward enough to bind the needle. However, this was quickly and easily remedied and the meter has been performing well ever since. I like it.

Rated 5 out of 5 by from OutstandingI have been calculating shunt resistors for panel meters for many years and this meter comes with an outstanding pre-calculated shunt resistor. I have found it to be outstanding for measuring DC current. I read the previous two reviews and cannot help questioning if the first reviewer really understands that the shunt resistor must be installed in parallel with the meter (or the shunt is broken and should be returned). After all, that is what a shunt resistor means, i.e. "parallel resistor." In testing the resistor and the panel meter, I determined the meter is 9.4 ohms and the shunt resistor is 2.5 Milli-ohm (0.0025 ohm). You can use these values with the parallel resistances formula and Ohms Law to determine the current or voltage. Attached is an example circuit using this shunt and meter.

Rated 3 out of 5 by from The meter is fine the shunt was not correctI think there must have been a mistake on the shunt that came with the meter it will peg the meter with only a couple amps but the meter works with an other shunt.

Rated 3 out of 5 by from Why a shunt?This meter comes wit an external shunt, which means you can use a small, light twisted pair to run the meter while your 12 gauge wiring is isolated from the meter. This does 2 things, reduced copper costs and eliminated meter heating from a large current.

Velleman AIM6030A 30A DC Panel Meter

How to wire the Velleman AIM6030A 30A DC Panel Meter into an AC power circut?

Are these meters only useful for high current DC aplications (automobile woofers?)Can I build a shunt in an AC power line and use this meter?
Asked by: Eric
The shunt doesn't care if the current through it is AC or DC. What matters is that the voltage formed across the shunt when a current is flowing through it is fairly small and is probably too small, even with a 30 ampere current, to overcome the forward drop of any diodes you might use to rectify the AC "shunt voltage" (probably measurable in millivolts across the shunt) to a DC voltage which can be used to drive the meter. Remember, the voltage applied to the meter is equal to the current through the meter multiplied by the resistance of the meter coil. It takes very little applied voltage to smoke a meter movement. Unfortunately, even diodes with low forward voltages don't conduct significantly until about 0.3 volts, and this is probably about all the voltage you'll get from the shunt at full current. If you want to get complicated you can probably use a transformer to boost the voltage, then rectify it, then voltage divide it down to a safe level for the meter. Try a small 12 volt transformer with the secondary connected across the shunt. Then run the primary to a full wave bridge (use schottky diodes) and apply the output of the bridge to a potentiometer, maybe 10Kohms. Connect your meter from the wiper of the pot to the "low" terminal of the pot. Then SLOWLY turn up the pot until you get a reading. The accuracy will be poor at low currents and better at higher currents. I'm assuming your AC source is regular 60 Hz AC line power. If you need more voltage, use a 6 volt transformer, which will multiply the shunt voltage by about 20. You will need to calibrate your meter against a known accurate current meter. Good luck!
