At the heart of the power module is a Texas Instruments TPS22917 buck-boost switching regulator. This regulator ensures reliable and efficient power conversion, delivering an output voltage ranging from 1.2V to 5.5V, with a maximum output current of 3A. The module is designed to operate from an input voltage range of 3.5V to 5.5V, making it suitable for use with a wide range of battery chemistries and power sources.

The 025-003 Power Module RB3 features over-voltage, over-current, and thermal protection to ensure safe and reliable operation. The thermal protection is implemented using a thermistor and an on-board microcontroller, which adjusts the output voltage to maintain a stable temperature. The module also incorporates a low-dropout linear voltage regulator, which provides a stable 3.3V output for sensitive load applications.

The module is equipped with a 4-pin header, allowing for easy connection to various load configurations, including parallel, series, or a combination of both. It also includes a status LED, which indicates the power module's operating status. The module can be configured for normal or low-power operation using a solderable jumper on the bottom of the enclosure.

The 025-003 Power Module RB3 is designed to meet the rigorous demands of industrial and automotive applications, with a wide operating temperature range of -40 C to 85 C. Its compact size, high output power, and robust protective features make it an excellent choice for a wide range of applications, including portable devices, industrial control systems, and automotive electronics.

However, if cost is a major concern or you require a high-power output, then you may want to explore other options.

If you are looking for a high-efficiency, compact, and robust power module for your power supply application, then the 025-003 power module RB3 is worth considering. However, it is essential to evaluate your specific requirements and budget carefully before making a decision. You may also want to consult with a power supply design expert to determine if this module is the best fit for your application.

Details:

The numbers/letters in parentheses are equivalents put to help people find the correct tube. Cd/record does not play. This means that I have tested something not to its full extent. In regards to the case/ cover then this grading means case or sleeve is badly torn, scuffed, cracked and falling apart.

Or if this is in grading regard to the case/cover then there may be cracks case or cover torn, has rips along its edges scuffed quite badly. It is up to you make a judgment call and decide if it worth the risk of buying. So this shows what I get, and you get may be slightly different. This is a process, and it takes time.

Light and medium scratching. Very good - used light scratching to both the case and CD/record. In these cases it is best buying on as if was broken. All tubes have passed the gas and short tests.

May be good or above. That is what they are there for. Most have one. I am quite harsh on what is good and bad.

Then they are not included in the sale. It is impossible to describe every scratch, scuff or mark. Fully working. Use the zoom function and have a good look.

I use a tv7/u military spec tester which is calibrated. If I say untested. It is just my opinion and I would rather paint a bleaker picture of something than saying it better. Cd/record still plays OK.

All tubes purchased have loads of life left in them. If fully tested then that is what they are. Or have only gone so far to test it. Very good plus - used, some light scratching to either the case or CD/record.

Some marks cannot be cleaned off and some can, so do not clean an item if you wish to return it for reason. Glass marks etching/hidden UV products are used. So take a good look. In photographs we occasionally use props to display items in the best light possible. I also pack well.

If not fully tested, then items are tested to the full extent and may have something wrong that I discovered. I try to resolve any issue both our best interests. Rectifiers and diode tubes do not have trans conductance values. Please have a look at the pictures for cosmetic condition.

If it does not say base, stand, table, in either the main body of or title. Sorry for you having to read this but would be surprised how many people think the items come with my table or a part of anatomy and wife's legs that I have accidentally caught on camera. Take it from me. They will normally want to see the item and packing. Light scratching to the case/ cover.

When using the word matched it means in test results rather than cosmetic looks. I take lots of pictures so you can see cosmetics. May be very light scratching but not noticeable or the case/cover may scuffed a little, excellent very ware to both CD / record case/ cover. Vacuum tube testing, I do not sell just passable vacuum tubes.

Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint perfect condition, might need some service, now later. Cd still plays well. Like new - used but no obvious signs of use. I do not publish test results in the listing as what get, and someone else might get can be different.

Whilst I endeavor to put tubes together from the same year and look same, this is not always case. I have 4 of these machines and all display a slightly differing value if test the same tube, as two testers are never. Slightly heavier than above. Heavy scratching to the disc.

I may have the same tube but from differing years matched up in test results, which means they cosmetically or internally look a little different. Sorry about this, but there are those out that think it is clever to change parts and return faulty ones. Cover is in good condition but has normal wear and tear. Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they collectors items.

By buying on this item you agree to these stipulations and follow the instructions, of post office, or carrier. Medium to heavy scratching. I make mistakes once in a while. Then I have not test it.

Record plays, sometimes skips. Fair - the CD. I also sometimes use a Hickok 752 for testing, if state any values they are guide only. In regards to the case or cover, then case/ cover is just holding itself together.
