Summarization

This product is DC power supply,its output voltage can be adjusted according to different grades,and it has overload protection function.When the output overload can automatically shut down,and it can operate incandescent lamp and other electrical equipments whose instantaneous current are not beyond its rated current.

Technological Index

1.DC stabilized Output:

a) Nominal Voltage: 0V,1.5V,3V,4.5V,6V,7.5V,9V,12V,total 8 grades.

b) Rated current:5A.

c) The Deviation of Voltage:Each Grade ± (2%U_{nominal voltage}+0.1V).

d) Voltage Stability:Each Grade≤(2%U_{nominal voltage}+0.1V) when output current is 1A and input AC Voltage is in the range of 200V～245V.

e) Current Stability:Each Grade Voltage≤(2%U_nominal_V_oltage+0.1V) when input AC voltage is 220V and every grade output current changes in the range of 0A~1A.

f) Voltage Accuracy：≤0.1%U_{nominal voltag}_e.

2.Overload Protection:

The instrument can automatically cut off when the output current reaches 1.05-1.3 times of max value.

3.Power Input: AC 220V~240V,50Hz～60Hz.

4.Continuons Operating Hours:≥8h

Directions

According to the request, make the load connect to corresponding column spine, and should pay attention to positive and negative polarity.

According to the desired voltage of the load,adjust the knob in the appropriate position.

Connect the power supply cable to the 220V the mains supply.

Turn on the power switch,and the red indicator light is on when the machine has already connected the power.

1.When output is overloaded,the red indicator light is on,this power supply will cut off automatically.After eliminating overload,press button to recover the normal work..

2.After using,should turn off the power switch and unplug it.

Operation Principle

The instrument gets the low-voltage AC output by the step-down transformer. The voltage changeover switch changes the secondary tap of transformer to get the 6 grades voltage regulation.And the DC stabilized part consists of rectifying diode, smoothing capacitor and voltage-stabilizing integrated circuit

Notice

1.Turn on the switch, if there is not output, please check the plug and socket whether good contact has or not. In addition, check that the fuse is good or not.

2.When adjust the range switch, it should distributes strength evenly.

3.Do not dismantle casing, and prevent from the electric shock.
