0-30 VDC 0-3A Adjustable Laboratory DC Power Supply with LCD

This DC-regulated switching-mode power supply is highly accurate and has an adjustable output. The output can be used for constant voltage (C.V.) and constant current (C.C.). Both output currents and voltage are indicated on the white LCD.

In constant voltage mode, output voltage can be adjusted anywhere between 0V and 30V. The current-limiting point can be arbitrarily set in this mode.

In constant current mode, the output current can be adjusted continuously anywhere between 0 and 10 Amps.
