32-54V Adjustable Output DC-DC Step-Up and Boost Converter, 8-16V Wide Input, 65W Output

$75.00

The pt1-ABXS001A4-50V is a robust and stable power supply providing an output voltage adjustable from 32V to 54V, at a maximum of 65W. The module is built around the (non-isolated) ABB ABXS001A4X41-SRZ boost converter.

The design of this power supply has been optimized to provide the best dynamic output response at ~50V, using the Tunable Loop feature of the converter. For deployment, ideally an additional capacitance of 15μF in total should be placed (i.e. distributed) at the power consumers’ ends.

The input voltage can be anywhere between 8V and 16V (typically 12V), supplied through the screw connector.

The pt1-ABXS001A4-50V is a robust and stable power supply providing an output voltage adjustable from 32V to 54V, at a maximum of 65W. The module is built around the (non-isolated) ABB ABXS001A4X41-SRZ boost converter. The design of this power supply has been optimized to provide the best dynamic output response at ~50V, using the Tunable Loop feature of the converter. For deployment, ideally, an additional capacitance of 15μF in total should be placed (i.e., distributed) at the power consumers’ ends.

The input voltage can be anywhere between 8V and 16V (typically 12V), supplied through the screw connector. The module features an on-board fuse and the converter’s output over-current protection. The converter is also protected against overtemperature. The converter will automatically recover from hick-up mode once the output current is returned to its specified range. When the converter goes into thermal shutdown, it will wait to cool before attempting to restart.

Some translator logic has been added to the circuit to provide a (positive) logic ENABLE (i.e. remote on/off) signal (e.g. 3.3/5V). The converter’s PGOOD (Power Good) signal is available through a separate connector. Connect this (open-drain) line to a logic high (5V max) using a 10kΩ pull-up resistor.

Features

  • 8-16V wide input, power provided through screw connector
  • 32-54V adjustable output, at a maximum of 65W;
    power available through a screw connector
  • built around (non-isolated) ABB ABXS001A4X41-SRZ boost converter
  • very high efficiency, not requiring any heat sinks
  • circuit protected through an on-board fuse
  • protected against overcurrent and over-temperature
  • high stability (i.e., low ripple) through input and output filtering
  • (positive) logic ENABLE (i.e., remote on/off) signal (e.g., 3.3/5V)
  • PGOOD (Power Good) signal (5V max, via a pull-up resistor) available
  • 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: 70.49×35.56mm; bolts: 64.14×29.21mm (M2.5)
  • high-quality PCBs designed in KiCad and produced by Aisler (Germany), PCBWay (China), and OSH Park (USA)
  • board comes fully assembled and tested

NOTE: the full output voltage range runs from about 32V to 54V; 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

NOTE: the output voltage is equal to the input voltage when the ENABLE signal is low

Usage

I’ve created this board as a high-voltage power supply to drive the grids and segments of the VFD display tubes I’m using in my projects. A similar module providing an output voltage up to 34V at a maximum of 65W is available here.

Shipping Policy

Please check your SPAM folder to ensure you accept emails from OzRobotics.com to receive your tracking number and download product-related files.

WE SHIP WORLDWIDE: We primarily ship via FedEx, UPS, DHL, and USPS because they’re reliable, fast, and easily trackable. We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, the delivery may take about 7 to 10 business days, depending on the shipping destination, logistics, weather conditions, product weight, size, or shipping company distribution structures.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. To benefit from lower shipping costs for orders with multiple items, please contact us at sales@ozrobotics.com. Our shipping rates are listed clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country. The total amount for your order does not include a customs fee/tariff. The United States Customs and Border Protection (CBP) deducts import tax, or customs duty, on goods valued over $800 USD from customers located in the US. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
