Description

DPS series digital input adjustable DC power supply, LED Display Mobile phone repair power test regulated power supply

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. 

Input voltage: 110V/220V ±10%50/60Hz

Output power: DPS-305BF 0 to 30V 0-5A
DPS-305BM 0 to 30V 0-5A

Option 1: DPS-305BM: BM: Four digit display,accuracy ±0.001A(1mA)

Option 2: DPS-305BF added function: BF: Five digit display,accuracy±0.0001A(0.1mA)

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

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

added DC power 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.
