5Ps Display High precision Digital Control Regulated Variable DC

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.
 
BM and CM have function and function difference:
 
1common features: constant current and constant voltage, constant current and Ma Ma measurements, the output opening, fast voltage all step functions.
 
2 CM increased function: a quick call10 groups of voltage and current data and storing the user required10 groups of voltage and current data, password lock keyboard, prevent misuse or vandalism operation.

Four usage notes
 
1, the initial state power:
 
Power every time when energized, the first display888-888digital tube display models, and then, on the display a setting voltage and current values, and finally into the working state and output.
 
2, the value of the input voltage
 
A step input
 
123456keys are 10V / 1V / 0.1V step lifting key, in order to prevent misoperation damage load, lift the 10V must also press 4 and7 or4 and1to lift.
 
B key input
 
Column : the need for13.8V output voltage
 
According to the voltage V respectively by 138press ENT key to finish last.
 
Column : the need for9V output voltage
 
According to the voltage V by 9followed by the ENT key is complete.
 
Column: need to output 4.5V
 
According to the voltage V by 4.5Finally, press the ENT key is complete.
 
According to the voltage V respectively by 04.5Finally, press the ENT key and a result is the same as above.
