Product description: LongWei Laboratory Power Supply LW-3010E 0-30 V 10 A
A programmablelaboratory power supplyunit enabling voltage regulationfrom 0 V to 30 Vand current regulationfrom 0 A to 10 A. The device has an easy-to-read three-level display, which shows the values of voltage, current and power. The LongWei LW-3010E can operate in the following modes: constant voltage output stabilization(C.V) andconstant curentcurrent 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. TheRS485communication port is located in the rear part of the device.
