Description
The QJ3003P QJ3005P is a highly accurate, DC-regulated power supply with an adjustable output. This
output can be used for constant voltage (C.V.) and constant current (C.C.).
The output voltage can be adjusted between 0V and 30V when the device is in the constant
voltage mode. The current-limiting point can be set arbitrarily in this mode.
The output current can be adjusted continuously between 0A and 5A in the constant current mode.
The output current and voltage are indicated on the LED displays.
