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.
