Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
Applications:

In addition to driving resistive loads such as LEDs, the eletechsup DD2913MA module can also drive inductive loads such as motors by adding a protection circuit.
If the voltage is not suitable for your application or you purchased the wrong voltage version, you can change the output voltage by modifying the R1 resistor.
* Delivery Time.
We need 1-2 days to process your order before shipping.There are two shipping methoed. Fast Delivery: The delivery time for US, European countries the delivery will take 3-5 days.Slow Delivery: The delivery time for US, European countries the delivery will take 10-15 days.
* Tracking information.
After we ship package, customer receive automatic email with tracking details.
* Lost Package Policy.
If a package did not arrive in 4 weeks after the shipping date, then this package is treated as Lost. In this case a new package will be shipped to the customer provided we are able to give the same items as those purchased by the customer. If we are not able to provide the same items to substitute the lost ones we will either propose to the customer similar items or refund their cost as it will be mutually agree with the customer. If one or more items neither the same nor similar are available to be shipped, the customer can request to cancel the order entirely, thus the total cost of the order including shipping and handling cost will be fully refunded.
