5-15.5V Adjustable Output DC-DC Power Supply, 19-40V Ultra-Wide Input, 3A Out

The pt1-OKIT36W40-15V5max is a robust and stable power supply providing four outputs, adjustable from 5.0V to 15.5V, at a maximum of 3A. The board is built around a Murata OKI-T/36-W40 DC-DC switching (buck) converter, not requiring a heat sink. The input voltage can be anywhere between 19V and 40V, supplied through the screw connector or the barrel jack connector. The module features an onboard fuse, protecting the circuit against sustained input reversal. The power output is also protected against short circuits and over-temperature. The converter will automatically restart after the short circuit condition is removed. Some translator logic has been added to the circuit to provide a (positive) logic ENABLE signal (e.g., 3.3/5V).

Features

  • 19-40V ultra-wide input, power provided through screw or barrel jack connector
  • four outputs, adjustable from 5.0V to 15.5V, at a maximum of 3A in total
  • built around Murata OKI-T/36-W40 DC-DC switching (buck) converter
  • very high efficiency, not requiring any heat sinks
  • protected against sustained input reversal through an onboard fuse
  • protected against short circuits and over-temperature
  • automatic restart after a short circuit
  • (positive) logic ENABLE signal (e.g., 3.3/5V)
  • all based on robust through-hole components (except for the OKI-T/36-W40 converter)
  • the board is standing on four brass standoffs, allowing you to place it on a working table or integrate it into a larger assembly
  • board size: 52.75×34.00mm; bolts: 46.75×28.00mm (M2.5)
  • high-quality PCBs designed in KiCad and produced by Aisler (Germany), PCBWay (China), and OSH Park (USA)
  • the board comes fully assembled and tested
  • power cables available

NOTE: the total output voltage range runs from about 5.0V to 15.5V; if you need a more limited range (to protect the hardware you will be connecting to this module), select one of the other (more restricted) ranges

NOTE: the module will only start when a high logic ENABLE signal is provided; if you need a module that is always on, select the type without the ENABLE signal logic

Usage

I’ve created this board as a low-voltage power supply for my LED applications (often based on the TI TLC5947 constant current LED driver) and to feed the filaments of the VFD display tubes I use in my projects.

Shipping Policy

We ship directly from the country where the product is made, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs.

Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated based on product weight rather than quantity. To reduce shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before placing your order. We show shipping rates on the product page under the SHIPPING tab. To view the shipping cost for your country, click 'Add to Cart' on the product page.

All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations require reverse tariff payments and multiple shipping fees, which are very costly and time-consuming. For technical issues, we will be happy to assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.

Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund. However, we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you, as the customer, will be responsible for the re-shipping fees and tariffs. If the product you purchased is defective, email us at support@ozrobotics.com with photos or a video of the faulty parts so we can evaluate the issue before arranging a replacement.

We’re here to help you buy the hottest products affordably, with fast shipping and World-Class Customer Support. However, please review the newly imposed tariffs and the Delivery tab to review our Return and Refund policies before making a purchase. Our prices are in US dollars.

Tariff: We ship directly from the country of origin, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs. Since we don’t always ship products to you from the USA (except for products made in the USA or stocked), you won’t be affected by the new tariffs imposed by the USA. Due to new tariff agreements, not all products are subject to tariffs, as tariffs vary by country and product. For example, customers in the USA will pay a tariff on products imported from China, based on the tariff rate agreed between the USA and China. If applicable, you, the customer, will pay the tariff in your country. The total amount of your order does not include a tariff, which you’ll pay before the delivery. We won’t refund if you don’t pay the tariff.

Why aren’t we adding tariffs to the product’s retail price? If all countries imposed the same tariff amount and used the same currency, we would have added that tariff to the product’s retail price. Our suppliers and we are not responsible for tariffs. Please shop accordingly.

Ships From: On this product page, check the Ships From: label to see which country the product ships from. We do not ship all products from the USA; some products ship from regions such as China, Taiwan, Canada, and Europe. Therefore, the tariff you pay depends on the country of origin, as not all countries charge the same rate. For example, suppose the US imposes a 30% tariff on goods imported from China; in contrast, other countries may impose a significantly lower tariff, or even none at all, on goods shipped from China into their countries.

Attention! We will email you the tracking number so you can follow your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff. However, as the customer, you are responsible for responding to their calls, texts, or emails. You can also use the tracking number link we emailed you to contact the shipping company and pay any applicable tariffs, if you haven’t already.

Heads Up! We’re not responsible for parcels returned to us if you don’t pay the tariff or fail to follow up with the shipping company. As a result, if the shipping company returns the parcel to its country of origin, you will be responsible for reshipping costs and applicable tariffs. We will not accept any excuses for nonpayment of the tariff or for failing to follow up with the shipping company regarding the tariff, and we will not issue a refund.
