DC POWER SUPPLY

Instruction Manual

(Please read carefully and thoroughly this instruction

manual before operation, and keep it safely.)

extinguish, restart power switch. (Voltage adjustment knob must be

turned to the minimum or output voltage less than the limited

voltage.)

(9) Attention: Don't start power switch with the load. Otherwise, easy

to damage DC Power Supply and the load. When the load current

more than 10A,Please use the rear output terminal. When use large

current, wiring terminal and output line must tighten. Otherwise,

wiring terminal will be damaged caused by connecting the big

resistance leading to fever.

4、Repair

4-1 Fuse replacement:

If fuse is burnt out, the power supply will stop working. If such

case occurs, its cause must be found and corrected. Use same type

fuse replacement. Do not open the fuse box, unless problem occurs.

4-2 Repair:

If the interior of the power supply is burn out, it must be repaired by

professional maintenance personnel or by the manufacturer through

the distributor. Do not repair it by yourself for the safety reason.

1、Summary

RXN-3020D、JPS-3020D、RXN-3030D、JPS-3030D are single output

power supply.RXN-302D(A)-II、JPS-302D-II、MPS-3002L-3、

RXN-303D(A)-II、JPS-303D-II、MPS-3003L-3、RXN-305D(A)-II、

JPS-305D-II、MPS-3005L-3、RXN-3010D(A)-II、JPS-3010D-II、

MPS-3010L-3 are three-output power supply, collectively referred to as

high precision constant current, constant voltage DC Linear Power

Supply .Characterized by high precision and strong reliability. And the

three-output power supply with auto tracing, auto series and parallel

operation.

KXN-3050D、KXN-3060D、…KXN-30010D are high efficiency

constant current, constant voltage DC Switching Power Supply. This

series DC Power Supply feature is strong ability to load and work for

low failure rate. Also they with the over-voltage protection,

over-temperature protection, over-load protection, over-current

protection functions.(work efficiency≥86%)

RXN、JPS、MPS、KXN series constant voltage constant current DC

Power Supply design for technology product development, laboratory,

junior college, electronic production line and communications industry.

The technical parameters please see the table.

Caution: KXN Series are Switching Power Supply. Internal

have high-pressure circuit. Not professional

maintenance personnel must not repair, lest produce

danger.

3-2 Method of operation:

(1) Connect the machine to the mains supply: AC220V±10%.

(2) Adjust over-voltage protection knob and current adjustment knob to

the maximum along the clockwise direction.

(3) Put power switch to the “ON”, and the red pilot lamp will go on.

(4) Adjust voltage coarse and fine adjustment knob to the required

value.

(5) Connect the external load to the “+” and “－”output terminal.

(6) When it is used to meet high requirement, the binding post of

output “+”or “－”must be connected with “GND” binding post to

reduce the output ripple voltage.

(7) Constant current setting: First adjust the voltage to 3-10V arbitrary

value, then adjust current adjustment knob to 0(turn it to the end

anticlockwise).Using the line to connect the output of the positive

(“+”) and the negative (“-”) electrodes. Then clockwise adjust the

current adjustment knob to the required current value. Remove the

short-circuit line, adjust voltage adjustment knob to the required

voltage value, and now it is ready to be used.

(8) Over-voltage protection setting: First adjust the over-voltage

protection knob to the maximum along the clockwise direction.

Then turn on power switch. Adjust the voltage adjustment knob to

the required protection value. Then anticlockwise adjust the

over-voltage protection knob to over-voltage protection. Use

voltage must be within the scope of your limit. Otherwise it will

automatically protect. Meanwhile, the over-voltage protection pilot

lamp will go on.

Restart steps after the over-voltage protection: First turn off power

switch. After over-voltage protection pilot lamp completely

3、Operating Instruction

3-1 Notice:

(1) AC input: AC 220V±10% 50Hz（If input voltage is 110V±10%

60Hz, on the rear of the machine will have marks）

(2) Insulation: The radiator in the rear of the machine should have

enough space to dissipate heat.RXN-3020D、RXN-3030D and

KXN Series DC Power Supply have temperature control switch.

When inside temperature≥45 radiator fan start to rotate to℃

dissipate heat. Do not use the machine in a place where the

temperature is over 45℃.
