The user interface of the QL564 models has been designed to provide rapid control whilst guarding against any possibility of error. Unlike other digitally controlled units, the QL564 models provide both numeric and rotary control. Illuminated keys and display legends provide instant confirmation of settings and status.
The QL564P model includes all of the manual control features of the standard models plus comprehensive digital interfaces and rear terminals. All power supply settings can be controlled via the bus. Voltage and current can be set to a resolution of 1mV or 0.1mA for each main output. Actual voltage and current can be read back along with the power supply status. For these models the maximum output voltage is 56V and the maximum output current is 4A. Two ports are available to choose from QL564 or QL564P.
