3.First, What can i do for you- Digital DC Power Supply-1502D+ ?

1.Digital DC Power Supply-1502D+  is specifically designed  for laboratories, schools, factories, production lines and Engineering department. it's output voltage is continuously adjustable from 0 to nominal value; output load current is also continuously adjustable from 0 to nominal value. Digital DC Power Supply-1502D+ haave very good stability and overload protection circuit.

4. How to  correct operation the Digital DC Power Supply-1502D+

(1) AC input: AC input for AC 220V ± 15% 50HZ (if it is 110V ± 15% 60HZ in the back of the chassis will be marked).

(2) Insulation: Do not use where the ambient temperature exceeds 40 ° C, the radiator in the rear of the instrument, should be sufficient space to facilitate cooling. Full load, prolonged use of high heat sink temperature, please do not touch the radiator.

(3) The output voltage overshoot limit: When the switching power supply, the output voltage can not afford the preset value. (If necessary with an accuracy of 0.1% multimeter to measure, such as overloading the necessary protective measures should be used to prevent static voltage is too high for any loss plant is not responsible for).

5.the method of operation

(1) power switch to "OFF" position.
(2) ensure that the input supply voltage is correct.
(3) connected to the power supply.
(4) the power switch to "ON" position.
(5) to adjust the "VOLTAGE" and "CURRENT" knob to the right output voltage and current values. (if Without limiting functionality may be the current knob CURRENT clockwise to maximum)
(6) to connect an external load to the "+", "-" output terminal.
(7) When used in a higher, the output terminals "+" or "-" terminal must have a reliable connection to the GND terminal, thus reducing the output ripple voltage.
