Hi foojook, are you talking the voltmeter on the LM2596 Buck Converter Could you please connect the multimeter on terminal in parallel, then tell us what’s the reading.

Looking forward to your reply.

Regards.

Hi, thanks for your message. but this meter cannot measure negative current. this Voltmeter Current Meter can meet your requirement.

Here is the DROK DC Voltmeter Ammeter Dual Display, you can choose the meter according to your requirements.

Any other questions, don’t hesitate to write back to us.

Thanks.

Hi, the 3 wires on the meter is ok, they are just signal wires and without a large current flow. the power of the meter is taken directly from the test circuit, so the red wire should connect to the positive of the auxiliary battery. It’s better if you can send us your hand painted wiring?

Looking forward to your reply.

Best regards.

Yes, it is ok. But the place as the below image is better. Because the current between thin red wire is small and more easier to control.

Hi, Is it the LM2596 Voltage Regulator you purchased? Could you tell us what’s your input voltage and output voltage.

Please note that this is a step down converter. If you need to increase the voltage, the input voltage must be 1V higher than the output voltage.

Looking forward to your reply.

Best regards,

Hi,

Thanks for your message. Just to confirm that the max DC output of the stepper motor is 60 volts, right? Please note that the input of our buck converter is DC 5-35V, so if the input is too high, it will be broken easily.

Please check if the input is too low when you connected a small 14 volt light bulb. If the input is too low, then you can know that the power of your generator is not enough.

Of course we can give a wholesale price for a bulk purchase. Could you tell us how many you want to buy. We still have about 400 units in amazon warehouse which can is shipped from US. If you want to buy more, we can ship it from China via DHL or other ways.

Looking forward to your reply.

Best regards,
DROK
