Product Description

YIHUA 305DB variable dc power supply , multiple / triple / dual output dc power supply


1.  4-digit display for accurate displaying of voltage and current values 
2. Current protection adjustments are very intuitive and easy to operate.
3. 305DB features 3 positive and negative output voltage and current values. The 3 outputs
can work simultaneously, but the 3 output voltage values cannot exceed 30V, and the 
current value of the 3 outputs cannot exceed 5A. 
4. The machine is built with SMT manufacturing and the latest technology. 
5.  Outputs can be turned off and current and voltage protection can be set to protect test 

6. 60 voltage and current values can be stored, and required voltage and current values 
be set and selected when needed for utmost convenience. 
7. The machine can be controlled via remote PC operation through simple software.
8. Adjustable current protection knobs allow for simple and intuitive operation.

YIHUA 305DB variable dc power supply, multiple / triple / dual output dc power supply,  have above all YIHUA305DA features and merit ,and additional to the following features
