DPS Series Digital DC Power Supply for Phone Repair  0-30V 0-5A 110V 220V 


Due to the voltage value is a digital keyboard input, shorten the voltage setting time, completely overcome the traditional potentiometer adjustment poor contact caused by voltage instability phenomenon. The internal power supply containing electronic switch, can conveniently open the output load.

Optional Type:

Optional 1: DPS-305BM

BM: Four digit display,accuracy ±0.001A(1mA)
BF: Five digit display,accuracy±0.0001A(0.1mA)

Optional 2: DPS-305BF added function:

Power sound alarm function
Mobile phone signal test
More curren digit display

Optional 3: DPS-305CF added function: Newer version more than DPS-305BF, added Memory storage and password Memory lock function.

(Cable:  44 pcs power convert cables)

Value added function : a quick call 10 groups of voltage and current data and storing the user required 10 groups of voltage and current data, password lock keyboard, prevent misuse or vandalism operation.
