High voltage Variable Voltage DC Power Supply for soldering station
YIHUA 305DB 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 ,audio-visual,it operation convenience .
3. the device have 3 groups positive and negative current and voltage output connector,so you can use 3
groups output working in the same time,but please pay attention to it,the total current can't
over the machine current,it means can not over 5A,please note.
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.
YIHUA305DB DC power supply have above all YIHUA305DA features and merit ,and additional to the following features:
1. it store up 60 groups current and voltage value,you can set you want to use value,very very
convenience.
2. the device can use software through the computer control the machine,you can use computer set all current and voltage
value.
3. it through computer long-distance control the device,but also have Programming function ,if you need use it.
4. YIHUA305DB the current can though the knob adjustable current protection ,more audio-visual,it operation more convenience .
