Adjustable Output DC-DC Power Supply with Ultra-Wide Input and 3A Output

Price range: $37.00 through $37.75

The pt1-OKI78SRE-5V-3V3 is a robust and stable power module providing four 3.3V outputs and another 5.0V outputs for each of the two voltages at a maximum of 1.5A. The board is built around two of Murata’s fixed-output DC-DC switching (buck) regulators from the OKI-78SR series, which provide far higher efficiency than any linear power regulator and thus do not require heat sinks.

The input voltage can be anywhere between 7V and 36V, supplied through the screw connector or the barrel jack connector.

Both power circuits feature their fuse (protecting the circuits against sustained input reversal) and an indicator LED. The power outputs are protected against short circuits and over-temperature. The converters will automatically restart once the short circuit condition is removed.

0.75-4.5V Adjustable Output DC-DC Power Supply, 9-32V Ultra-Wide Input, 3A Output

The pt1-OKIT3W32-4V5max is a robust and stable power supply providing four outputs, adjustable from 0.75V to 4.5V, at a maximum of 3A. The board is built around a Murata OKI-T/3-W32 DC-DC switching (buck) converter, which does not require a heat sink. The input voltage can be anywhere between 9V and 32V, 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. The circuit has added some translator logic to provide a (positive) logic ENABLE signal (e.g., 3.3/5V).

Features

  • 9-32V ultra-wide input, power provided through screw or barrel jack connector
  • four outputs, adjustable from 0.75v to 4.5V, at a maximum of 3A in total
  • built around Murata OKI-T/3-W32 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/3-W3 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 0.75V to 4.5V; 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 requires a different fuse depending on the input voltage (2A for ~12V input, 1A for ~24V input); make sure you select the suitable module for your application

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

Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they are fast, reliable, and easily trackable. We process orders within 24 hours, and delivery may take 4-7 business days after that, depending on your location. We will email you the tracking number once your order is shipped.

Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated based on product weight, not 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.

Return Policy

5 Hours: Mistakes happen when ordering, so you have 5 hours to request a refund for any reason, including if you don’t want to pay the tariff. However, Stripe will not refund you their processing fee if you cancel your order.

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. But we will offer an exchange for a product that has irreversible manufacturing defects or technical problems. 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 it before arranging for a replacement.

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

Tariff: We ship directly from the country where the product is made, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs. Since we do not always ship products to you from the USA (except for products made in the USA or stocked), you will not be affected by the new tariffs imposed by the USA. Due to new tariff agreements between countries, not all products are subject to tariffs, as tariffs vary by country or 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. And so, if applicable, you, the customer, will pay the tariff in your respective country. The total amount of your order does not include a tariff, which you will pay before the delivery. We won’t issue a refund if you don’t pay the tariff.

Tariff via UPS: Click the Order Tracking link we emailed you with your tracking number, or call UPS at 1-800-742-5877.

Tariff via USPS: Click the Order Tracking link in the email we sent you to view your tracking number, or call 1-800-ASK-USPS (1-800-275-8777).

Ships From: On this product page, check the Ships From: label to see which country we will ship this product from, because we do not ship all products from the USA; some products ship from regions like China, Taiwan, Canada, and Europe. Therefore, the tariff you pay depends on the country your order is shipped from, as not all countries charge the same tariff. 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 for you to track 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 call, text, or email. You can also click the tracking number link we emailed you to contact the shipping company and make the tariff payment, 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 re-shipping costs and tariff charges. We will not accept any excuses for not paying the tariff or for failing to follow up with the shipping company for the tariff, and we will not issue a refund.

Why are we not 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.
