I can only agree with my predecessors. The device makes a good, robust impression. The operation is easy to learn. The enclosed instructions are rather confusing. The fan also runs (very quietly) without load. When the outputs are switched off, the target/ Maximum values are displayed. When the outputs are switched on, the device displays the actual actual values. If the setpoint/maximum values are changed, the display switches briefly. By selecting (pressing a button) the digit to be set, the setpoint can be changed very sensitively. Voltage +/ -10mV current +/- 1mAThere is also an overflow. Great! Well thought out and precise. Residual ripple is about 2mVI tried to locate the manufacturer (Stamos/Expondo). I found out that the device was probably manufactured by Korad (China).The S-LS-28 is probably identical to the KD3305D, which is a lot cheaper .Maybe someone has more information about it.But despite the price, I am very satisfied with the device. Recommendation!
Delivery and product all perfect. Recommended.
Fast delivery, equipment received without transport damage. It remains to test the operation but everything seems fine.
I can finally dispose of my older laboratory power supply. I left the device there for a day - then switched it on... What can I write, I'm thrilled. Great price-performance ratio. No fan noise. The operation is understood in just a few minutes. Then it was first checked and tested. With my resources I couldn't find any errors. Thanks to the expondo team
A linear power supply, solidly built, the first impression is really good!
Definitely functional and well made.
I'm amazed that the device has been checked for performance. The operation is intuitive enough for electric technicians! Power cut-off perfect. The third channel is also great. If you need something for the laboratory, definitely buy it.
Nice and solid, it does its job well. Advised !!
No comment provided.
The power supply works very well; the regulation is precise, except that it is not continuous but in steps; Fortunately the steps are very close together, so there are (almost) no problems in fine adjustment. The only problem (later resolved) with assistance as it took MONTHS to get the invoice with the correct header. The product therefore costs a little more than the average power supply that can be found online but it's worth it; if you have no problems or billing requests (perhaps resolved now) don't worry. Recommended.
