🔴 FNIRSI DPS-150 Power Supply Review - No.1289

FNIRSI DPS-150 Portable Power Supply Review

I review the DPS-150 from FNIRSI, I test on my DC electronic load, check for overshoot at turn on, take it apart and show the user interface and functions.

On the last page of the manual you'll find "The product operates in step-down mode, so ensure that the input voltage is higher than the output voltage."
That's so cheap to make it sound like it's a buck/boost, step up/step down converter until you find out on the last page in the manual. Also very weird to not use a buck/boost module in a product like this, I wanted a portable option to use with a 5V power bank, but this was a no go for me.

They should start thinking of implementing PD3.1. With the 48V available, they can do 0-30V really easily.

They could also do a version that does 0-60V 1A.

[pault]

The purpose of the 5V input and switch might be to power the unit without relying on the power source - which can have several advantages. Not sure why they call it a power supply, it's more a power management system.

The micro USB is to hook it up to a PC and use the companion app.

[OneTheAndOnlyOne]

the micro-USB is to connect it to a pc

[JAKOB]

You do have all the 5v input you could want.. 40:44 that is as far as you can come from a fault, it would be a fault, if it alloved you to use that MicroSD connection as supply.
if you wanna use 5v.. then use the intended TypeC with a TypeC cable and a 5v PSU.. its will accept the full monty. 5v, 9v, 12v, 15v 20v and all the fastcharge protocols on that USB TypeC.
Nobody on a modern device would use MicroSD for a power supply, as its a connection standard that had issues when going above the nominal 5v 2.4 / 12W standard.

[rodrigomaero]

You could use a USB-A to USB-C cable with a regular 5V charger to power it and feed the low voltage, low power loads

[hitchjay]

Why does it not ask for 28v from PD? is it PD3.1? also, would be interesting to see if it renegotiates the PD supplied voltage on the fly when stepping up/down the voltage for better efficiency

[QsTechService]

wow, that thing is compact looks like it would be nice for travel, size and everything I wonder how it would work on finding shorts injecting voltage into boards

[JAKOB]

You can obviously also run it on Powerdelivery 3.1 (28v/5A 140W) that does with it well.. it wont trigger for you, lacking the 3.1 chip, but you do it outside (see EEVblog for details.. same on AlienTek DP100)
it will accept it from either input TypeC or Barrel-DC.
Try charging batteries with it...and enjoy the kickback from the donkey...

I see you have the Fluke 289. I love mine. It's also a data logger. Have you used the low ohm feature? The relative % feature is amazing for data line validation.

[valkohh]

Looks like perfect fit for my use. Can it flip the screen view depending on orientation, i would like to use tape or 3d printed pieces to attach it to my bench table upside down. Always been a fan of fnirsi they seem to beat the bang for the buck market real good, beating quality too.

[Turco]

There is a standard and an Advanced version, difference being the Advanced version comes with a USB-C power supply like the one in the video. So would you recommend this which is typically selling for close to $100 US? I was looking for a digital display providing the same type of information when I connect to a laptop DC port, so I can see how much power the laptop is drawing if any.
Would this work for that type of testing/connection? Is the type-C port for output so I could use a type-c charging cable and appropriate DC adapter and hook this up to different brand laptops and phones?

[diffmull]

Nice review, but would have been nicer without the beeps. Luckily, there is always the closed-captions option.

[splitprissm]

Wonder if these could make good building block for a computerized curve tracer?

---

Do these share a ground with the USB power supply, or offer galvanic isolation?

[rucoa]

It seems the overpower protection only works once. Then you have to unplug the device for it to protect again.

[TheEmbeddedHobbyist]

For something that can run 150W there does not seem to be much in the way of heat sinking.
How can they refer to it as a PSU when it needs an external PSU to work.

[jamesmason]

The link for the power supply only goes to your t-shirts

[miladmohtashami]

THIS IS JUST buck. It doesn't output more than the input voltage. I wish this guy had said that it this piece of shielectronic only do step down not step up. almost all the USB PD chargers around go up to 20V. which makes this thing only upto 20V. such a waste of money and time watching this video.

[bsssddsssb]

After working an hour, the capacitor exploded and stopped working, dont buy.
