Product Description
Variable voltage dc power supply 30V 5A YIHUA305DA
YIHUA 305DA dc regulated power supply feature:
1. have 4 digital display show the voltage and current value,it shows value very very precision .
2. it can adjustable the current protection value directly, audio-visual,it operation convenience .
3. the device have 3 groups output for current and voltage,so you can use 3 groups output working in the same time.
4. the machine arts and crafts is SMT ,all use the latest technique .
5. you can turn off the output ,set the protection current and voltage,this way can protection you test device.
