Product Description:
220V DPS-305BM Digital Control 30V 5A DC Voltage Regulated Power Supply DPS305BM for Laptop Repair
Feature
DPS series digital input adjustable DC power supply is designed for laboratory, school, production lines and electronic repair designed for use. Voltage stability is high, small ripple factor, has improved the short circuit protection and overcurrent protection. 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.
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.
