RD AT35 USB 3.0 multimeter
[Delivered to Croatia in 2 weeks. USB meter has beautiful display and is very practical and easy to use, comes in a nice plastic box with foam which is great for storing and carrying around. USB load meter is nicely put together, and is also easy to use. I would suggest putting better plastic standoff legs and perhaps knob on a potentiometer. Also foamy box so that it doesnt flap inside. Overall, very nice products for amateurs and pros. I will order more in future. Love this seller and their products.]

RD DPS5020 Constant voltage current DC- DC Step-down communication Power Supply
[I liked the device, for a long time "lay" in "My wishes." So far, it has shaken by about 250 - 280 watts, although it is possible up to 1000 watts. There is no more power supply yet. All the declared parameters work, on the bluetooth of the device it connected without problems to a smartphone and laptop. By USB, too, no problem. A small minus, in my opinion, is a constantly noisy case fan. I can recommend a great device! I ordered the maximum configuration of the DPS5020.]

Hello RDTech.

I’ve been loving your products, but I’ve been having a small problem.

Using it during chemistry experiments, it has been very useful.

However, being exposed to corrosive vapors on the outside, the outside case screws have started to rust after 9 months.

Could you provide measurements for the screws so I could buy stainless steel or titanium ones?

Thank you.

Edit: This was for the DPS5015 case. Sorry if I did not include it.

Hi friend
thank you so much for your message and your support
could you tell me which case you bough? metal case or aluminium alloy case?
i can provide the instruction, there is screw model name

It is the metal housing case, like on your DPS5015 product page.

RD DPS5020 DC Step-down Power Supply
[Emotions are positive! The seller is very sociable. Helps than it can. The device gives out its 20A and works normally from 50V input voltage. Alas, I use the source HJS-480-0-48 (500w). Either voltage or current. A kilowatt far, but enough for me. I can only say that at the output I used my wires (10mm²).]

[fast delivery does not support at the time of order, by default only an e-packet was available, it is impossible to imagine a longer delivery plane for a longer delivery, literally they carried it from China. and let this device be beautiful a thousand times, but delivery by e-packet has made a lasting impression. but the seller controls everything]
