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,

Hi, the website is not specifics, you can upload to this website, then send us the link.

The input can be connected in parallel, but the output cannot be connected in parallel. If you connect the input in parallel, which is mean to take power from a battery. But if you connect the output in parallel, the different output of the 2 regulators will form the current return circuit. the current will be large if the output voltage difference between the 2 regulators is large, then the regulators will be damaged.

Sorry for the misunderstanding. It doesn’t mean you have to use only one regulator per one battery, but please note that the output of per one regulator must be connect only one device.

And about the regulator you are looking for, we are sorry that we don’t have such regulator now.

Thanks for your understanding.

Hi, could you tell us which product you want to know? we have diagram on the website image for most of the meters.

Hi, thanks for your reply. If both of them emitted smokes, it’s better not to ues them any more. BTW, did you connect both of them in parallel? could you please send us your wiring photo by “add media” .

On the other hand, about your requirement, could you tell us more details, what’s the input and output voltage and what’s the load?

Looking forward to your reply.
Thanks.

Hi, as your description, we are afraid it was broken now. we have sent a message to your amazon account. please reply us and send us the picture, then can deal with your order directly.

Hi, this product just a constant voltage module, you need to choose a constant voltage & current module. Here is the one meet for your requirement.

Then if you have any other questions, don’t hesitate to contact us.
Thanks.

Hi, thanks for your reply. The max extend length is 55 feet for this thermometer. then if you have any other questions, don’t hesitate to write back to us.
Thanks.
