Laboratory power supply LongWei LW-3010E 0-30V 10A
Programmable laboratory power supply unit allowing regulation of voltage within the range from 0 V to 30 V and current within the range from 0 A to 10 A. The device has an easy-to-read three-level display, which shows values of voltage, current and power. The LongWei LW-3010E can operate in the following modes: constant voltage output stabilization(C.V) andconstant curent current output stabilization(C.C). Their current status is indicated by indicators on the front panel of the device. LW-3010E is a switched-mode power supply with fan cooling. The RS485 communication port is located in the rear part of the device.
