|
Provides CV and CC operating modes, switching automatically
|
|
The output voltage and output current are continuously adjustable from 0 to the maximum rating values |
|
The maximum rating current can be achieved at 10mV. Equipped with SENSE terminals to compensate for the line loss
|
|
High power factor, high efficiency, wide line voltage range as well as low output ripple and noise |
|
Multi-group setting parameters storage and recall |
|
Robust, compact and convenient |
|
SCPI (Standard Commands for Programmable Instruments) compatibility |
|
Reliable input/output protections guarantee the effective operation in severe environment |
