Rather small but cute! Advanced DC PS. The 2 knobs controlling V and I have a press switch. They can be rotated continuously in either direction. The switch controls each of the 4 digits. The V switch also controls the system settings. Three memory buttons are provided (long press to store and short press to recall). The PCB, switches and wiring are excellent. A few tiny spots of solder were stuck on the bottom plate. The heat sink is grossly inadequate. The thermostatically controlled fan intermittently turns on even for 10W loads. I didn't test it for max rating continuously. The display is correct, but there are no presets on the PCB for calibration. It automatically switches between CC and CV. Make sure the settings are correct before switching the output on. The supplied output cable may be ok for currents less than 5A. A better cable, clamps and banana plugs would be required for higher currents.

The customer quickly took out the product but the transfers took a long time. The product is high quality and sensitive as described. I am very satisfied.

müşteri ürünü hızlı çıkardı ama transferler uzun sürdü. ürün anlatıldığı gibi kaliteli ve hassa. çok memnun kaldım.

I refer to device type EPS1203, 0..120Vdc, 3.2A: - the device is compact and cleanly processed - the displayed values ​​agree with the measurement - it will have to prove itself, but I don't see any problems coming up to me - price/performance is perfect.

Ich beziehe mich auf den Gerätetyp EPS1203, 0..120Vdc, 3.2A: -das Gerät ist kompakt und sauber verarbeitet -die angezeigten Werte stimmen mit der Messung überein Es wird sich bewähren müssen, jedoch sehe keine Probleme auf mich zukommen. Preis-/Leistung ist perfekt.

Makes a great impression. For my purposes (power supply for ESP32 and Co) perfectly OK.

Macht einen hervorragenden Eindruck. Für meine Zwecke (Spannungsversorgung für ESP32 und Co) vollkommen OK.

This is a really nice upgrade from my old jumpy potentiometer style supply. It came with an EU cable, but I have lots of extra US IEC cables, so no big deal. The user interface is well done. Volt and amps are controlled with push-button rotary encoders. Just rotate to increase/decrease the number once per tick. Press to cycle through the digits, so it can be 1mA per tick to 1A per tick. Volts only goes down to 10mV. The OUT button turns output on and off. When off, it's in adjust mode. When on, it shows live volts/amps and adjusting makes the, I guess you'd call it the coarseness digit flash until you stop adjusting it for a few seconds, then sets the new output parameters. There's also a display brightness setting (just low and high) but they both appear the same. It's a good brightness anyway.

The power source is good. All parameters correspond to the declared ones. Cons: when voltage is applied to the load, the encoder adjustments and memory buttons aren't blocked, as implemented in serious labs. That means accidentally turning the voltage adjustment encoder or pressing the memory button with programmed increased voltage can kill the load. That's what happened to me when I accidentally pressed button M3 while supplying 5 volts to the load, thereby applying 30 volts to the load :(

Источник питания хорош. Все параметры соответствуют заявленным. Из минусов: при подаче напряжения в нагрузку, не блокируются энкодеры регулировок и кнопки памяти, как это реализовано у серьезных лабораторников. То есть случайно повернув энкодер регулировки напряжения или нажав кнопку памяти с запрграмированным повышенным напряжением можно убить нагрузку. У меня так и вышло, когда подавая 5 вольт в нагрузку, нечаянно нажал кнопку М3 тем самым подав в нагрузку 30 вольт :( "Защита от дурака" не помешала бы. Кроме того на дисплее никак не отображается ток через USB разъем. Сам USB поддерживает быструю зарядку, но посмотреть каким током не получится :( Приборного USB на задней панели нет, так что обновление прошивки скорее всего не предвидится :( В остальном источник вполне неплох и оправдывает свою цену.
