Review on Laboratory power supply (power supply) MAISHENG MS3010D-MS002 (30 V, 10 A) by Stanislaw Sipko ᠌

Holds the load. The display is correct. When reversed, you can easily adjust without disassembling the case. Stabilization works. The on / off button "cuts" to the board. Specially disassembled and looked. You can safely leave it on the network. The cooling fan is controlled by the board, the rotation speed is adjusted depending on the load. Previously, I did not use such devices and thought that the current limit could be set before the load was connected. At first I was upset that without a load on the ammeter display, the zeros show how much the knobs do not twist. Then I figured it out, you just need to short-circuit the "crocodiles" I will add: You can charge a car battery in the same way as an automatic charger. Stabilization allows this. We set the voltage to 14.5V and the desired initial current (for example, 6 amperes for a battery with a capacity of 60 Ah), connect the crocodiles to the terminals and go about our business. First, the device will limit the current (not higher than 6 A), the voltage will be below 14.5. Then, when the voltage rises to 14.5 volts, the device will begin to reduce the current. Then, for a full charge, you can increase the voltage to 15 V, or 16, depending on the type of battery.
