Programmable laboratory power supply that allows voltage adjustment in the range from 0 V to 30 V and current in the range from 0 A to 10 A. The device has a clear three-level display, which shows the voltage and current values and power. LongWei LW-3010E can work in the following modes: stabilization of the output voltage (constant voltage CV) and stabilization of the output current (constant curent CC). Their current status is signaled by indicators on the front panel of the device. The LW-3010E is a switching power supply with fan cooling. The RS485 communication port is located at the rear of the device.
