PWM Dimming control signal (2.8V-6V on)
Note: The signal must be connected to a common ground reference, otherwise the signal is unstable

For a certain frequency of PWM dimming, the output current of the driver has a certain relationship with the duty cycle of the PWM signal, the calculation method refers to this formula:
lo_set=(DT/T)lo_norm
Where, lo_set for the desired output current value (mA), D for the PWM signal duty cycle (%), T for the period of the PWM signal (S), lo_norm for the rated output of the driver (mA).
Caution:
The above formula is for reference only, the output current may deviate because of the different loads, the PWM signal can not be less than 0.7ms on-time limit, otherwise the product can not work properly, if you hear a slight sound from the driver when PWM dimming is a normal phenomenon, because the PWM dimming frequency in the range of human ear hearing.

  2. If the goods are returned due to the customer's failure to cooperate with customs clearance, the freight shall be borne by the recipient.
  3. We can provide consumption lists and certificates. Please contact us when customs requires.
  4. If the buyer causes the return, the buyer shall bear the freight, and the cost shall be based on the selected courier. If the goods are damaged or wrong due to our fault, APISQUEEN shall bear all costs.
  5. The value of the products we declare to the customs is 10% of the actual order amount paid by the buyer, so the buyer generally pays very little tariffs.

About Shipping

We can send goods to almost any country in the world! But you need to pay attention to the import restrictions of some countries.

In the case of no stock: the goods will be shipped within 3-20 working days after the buyer pays.

  1. Or there are other problems that delay the shipment, such as the address information needs to be further verified, but please rest assured that we will follow up in time to deal with it so that the goods can be shipped faster.
  2. Goods are generally transported by air. According to the buyer's location, we use different transportation methods. Generally, we use DHL, FedEx, UPS, dedicated lines, etc.
  3. The time for standard express delivery to the destination is generally 3-12 days (without other special circumstances), and the transportation time for remote countries/regions is generally 10-20 days. If you have other needs (such as designated express, customs value declaration, etc.), please contact us after placing an order to ensure that we can meet your requirements.
  4. APISQUEEN sets transportation rates according to different countries/regions. In order to reduce the buyer's purchase cost, APISQUEEN takes the initiative to bear 50% of the shipping costs for the buyer.
  5. Shipping costs are charged according to the weight of the goods and are settled when placing an order. The shipping cost shown in the settlement is the result after APISQUEEN bears 50%.
  6. You can estimate the shipping cost as follows: select the item you want to purchase → add to the shopping cart → enter the zip code of the delivery address → select the delivery method → ​​then you will receive the estimated shipping cost.

If you need the product urgently, please contact us before placing an order to ensure that we can meet your time requirements.

About after-sales

  1. The order can be cancelled before the product is shipped to obtain a full refund (including shipping costs). After the goods are shipped, if the buyer requests a refund for his own reasons (for example: he does not want it anymore, bought the wrong one, etc.), the buyer needs to bear the cost of the express delivery and return the goods to us. After we receive the returned goods, we will refund the buyer.
  2. If you find that your package is damaged during transportation, please contact us within 5 days of receiving the goods (Lynn@underwaterthruster.com), and provide photos or videos of the goods. We will handle it for you according to the actual situation within 1-3 working days to satisfy you.
  3. If you need to replace your purchased goods after receiving the goods, you need to mail the goods to APISQUEEN;Within 6 months after purchasing the product and confirming receipt, if there is any quality problem with the product, we will provide free after-sales service and mail new accessories or new products to the buyer free of charge (the buyer only needs to bear the express transportation fee, APISQUEEN will no longer help the buyer to bear 50% of the freight, and the buyer needs to bear 100% of the freight)

APISQUEEN refuses after-sales service in the following situations:

  1.  Failures and damages caused by non-product quality problems.
  2. Damage caused by circuit changes or improper matching.
  3. Damage caused by unauthorized modification or disassembly.
