Summarization

This product is AC/DC power supply (Type D is trio output.). Also,

it has the LCD voltage induction and stable circuit performance. The

output has overload protection: when it outputs overloaded, it will

automatically cut off the power source. In addition, connect the

ammeter and current-limiting circuit, it can charge for the small

storage battery.

Technological Index

1. AC Output

Nominal Voltage:2—12V, 1V for each grade. Total is 11 grades.

Max current: 8A

No-load Voltage: each grade ≦Unominal voltage+(0.5V+5%Unominal

voltage)

Full-load Voltage: each grade ≧Unominal voltage-(0.5V+5%Unominal

voltage)

2. DC Output

Nominal Voltage: 2—12V, 1V for each grade. Total is 11 grades.

Max Current: 8A

The error of Voltage: ± (2%Unominal voltage+0.1V)

Voltage stability: ≦ (2%Unominal voltage+0.1V)

Load stability: ≧ (2%Unominal voltage+0.1V)

3. Overload Protection: The instrument can automatically cut off

when the output current reaches 1.05-1.2 times of max value (8A).

4. Power Input: AC 220V/240V, 50Hz/60Hz.

Use

1. According to the request, make the load connect to corresponding

column spine. When use the DC input, it should notice the polarity.

2. According to the voltage that load needed. Make the Voltage knob

adjust to the corresponding position.

3. After the instrument connects to the mains supply.

4. Then turn on the switch, when the indicator light is on, it shows

that the instrument has electrified.

5. When output is overloaded, this power supply will cut off

automatically. After eliminating overload, press button to

recover the normal work.

6. After using, pluck off the plug of power supply. Furthermore, put

the instrument at cool, aeration and dry place.

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 11 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.

4. All pending issues please contact with the company.
