5
(1)
YIHUA 3005D-II Dual adjustable DC power supply is a dual-channel DC power supply with continuously-adjustable current and voltage, a large-screen LED-backlit display, and built-in knobs to help operators eliminate hidden dangers resulting from faulty adjustment. Channel II independent operations feature automatic tracking in series or in parallel. The third fixed output features selection between 2.5V, 3.3V, and 5V. Stunning in appearance and outstanding in performance, the machine is suitable for technology product development and use in laboratories, teaching, and electronics production lines as well as in essential communications industry equipment.
Features:
Independent Operations Mode ,it means the machine have 2 groups 30V 5A output voltage and current.
Series Tracking Mode,it means the machine max output voltage is 60V ,the max output current is 5A.
Parallel Tracking Mode ,it means the max output voltage value is 30V,the output current is 10A.
The device has Fixed output,”SER” mode ,can set fixed output,(the voltage fixed output value is 2.5V,3.3V,5V)
It features 3 positive and negative output voltage and current values. The 3 outputs can work simultaneously
4digit display for accurate displaying of current values,precise to mA value,the machine is built with SMT manufacturing and the latest technology
The amchine inside transformer is copper,and inside have fan ,when the machine work temperaute over 45 degree,the fan will be work,it is good for heating radiation,can prolong the machine life.
