訳あり商品ですでのでご理解のうえで購入をお願いします

  最大電流が12.6Aです(12.6Aで電流制限がかかる)

--------------------最大電流20Aの商品説明-------------------------------------------------
最大電力300W/最大電流20Aの定電圧&定電流DC-DCコンバーター基板です。
降圧タイプですので入力電圧>出力電圧での使用方法となります。
 
動作確認をした商品を出荷しますので基本的にNC&NRを納得される方のみの入札をお願いします。但し、不良内容の解析調査にご協力していただける場合はその限りではありません(評価が悪い方は除きます)

[主要定格]  購入先の商品説明より抜粋また動作確認したものですべての性能を保証するものではありません。
なお中国製の激安商品で使用部品もロットで異なっていたりするので完璧な品質を求める方は入札をご遠慮下さい。
 ・入力電圧:6V-40V(推奨10V~40V)・・・入力コンデンサは50V耐圧品
・出力電圧:1..2V-36V・・・出力コンデンサは、35V耐圧品なので注意
・最大出力電流:20A(推奨15A) 訳ありなので最大12.6A
・最大出力電力:300W・・・自然空冷ではあり得ない数値で使用条件にも依るが必要に応じて強制空冷が必要
・出力短絡保護:あり(長時間の短絡は不可)
・効率:96%(入力24V、出力12V/20A) 
・入出力端子:ねじ止め端子で最大30A
・入力逆接続保護:なし
・基板外形寸法:60 x 53 x 28mm(L x W x H)
・入力と出力とのGNDは共通でないので接続配線に注意して下さい
 
1.出力電圧の設定…出荷時は約12V
 多回転ボリュームを時計方向に回すと増加しますので電圧計やテスター等で希望の電圧値を設定して下さい。
2.定電流(最大出力電流)の設定…出荷時は約10A
 多回転ボリュームを時計方向に回すと増加しますので低抵抗を負荷にしてテスターや電流計等にて希望の電流値を設定して下さい。
設定出来る定電流値は、200mA程度以上は流れないと誤差増幅器(コンパレータ)が正確に動作しないので注意して下さい。
  最大電流値の設定が難しい場合は、当方で設定後に発送することも可能です。
3.動作状態表示LED
 出力電圧ありで点灯する単純な表示
 
<送料について>厚さ制限の為に最小限の梱包材で発送しますが、輸送中のダメージによる不具合また不達については責任を負いませんのでご了承のうえ入札して下さい。
  全国送料無料のゆうパケットポストmini(基本は陸路ですので沖縄等の遠隔地は日数がかかりますが土日/祝日もポスト投函されます)での発送となります。

Notes:

  • Compare the actual weight with the volume weight, and the larger one will be the billing weight
  • Volume weight (KG) = length (L) (cm) X width (W) (cm) X height (H) (cm) / 5000
  • Common volume weight products: furniture, fishing rods, car parts...
  • A "consolidation handling fee" (price list)
    
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.

※ Note: Photos provided to sellers should not contain any foreign-related information.
