leovavrik In den Drehknöpfen ist Masseschluss und die Tasten sind blockiert. Anscheinend Systemfehler, siehe youtube Reparaturanleitung.

Worked great for a few days then locked up numerous times. Took over a month and at least 30 emails to get it replaced.

Q: the gateway is only necessary for the configuration. or it must also be available for operation. what happens in the event of a power failure if the gateway does not work

Asked by leovavrik on 2021-12-10 05:58:53

macieymaciey I think that you can work without app, but you need it for configuration (Keys programming). Without app you won't be notified (many events: alarm, key inside, etc)

Nice adjustable power supply. I use it for the initial charge of my Li-ion cells. I hope that the voltage display works exactly. My (cheap) multimeter shows slightly different values. But since I only charge up to 4 VDC, this should not result in overcharging. Unfortunately, this power supply does not have a USB charging socket as is the case with comparable ones. Otherwise it seems to be a great power supply. Unfortunately there are no cables with banana plugs included.
