Thank you for your trust in our Power Products. After purchasing, please read the instructionscarefully and keep them in a safe place for better use.
Features:
Low ripple voltage, with high precision and high stability
This power supply is DF model DC regulated power supply.
The output voltage and current are continuously adjustable.
4-digit LED display, display output voltage, current and output power, and provide common 5V voltage USB interface.
The power supply is small in size, high in efficiency, moderate in weight.
Can be used for a long time under full power conditions, and the continuous operation failure rate is low.
The power supply has various protection functions such as over temperature, overload, current limit, etc., and users can use it with confidence. For research, colleges, factories and other occasions, it is your best choice.

Operation:
1, Note:
(1) AC input: Confirm that the input voltage is consistent with the switching voltage. The input voltage must be between 99-121V.
(2) Working environment: There should be enough space around the power supply to facilitate heat dissipation. When the internal temperature exceeds 75 °C, the power supply will stop working. When the internal temperature is lower than the over-temperature protection threshold, the power supply starts automatically.
2. Operation steps:
(1) Turn on the power with a three-wire power cord. (Make sure the input voltage is correct.)
(2) Press the 5 power switch. The indicator lights up and the LED is displayed.
(3) Regulator source use: adjust the 10 and 11 knobs clockwise to the maximum, adjust 8, 9 to the required voltage value, connect the load to the 12 and 14 terminals (note the positive and negative polarity is correct), at this time 7 constant When the voltage indicator lights up, the power supply operates in a regulated state, that is, the voltage does not change, and the current magnitude changes with load.
(4) Steady flow source use: adjust the 8 and 9 knobs clockwise to the required voltage, adjust 10, 11 to the minimum, connect the load to the 12, 14 binding posts (note the positive and negative polarity is correct), adjust clockwise 10, 11 to the required current value, at this time 6 steady current indicator lights up, the power supply works in steady current state, that is, the current does not change, and the voltage changes with the load.
