(5)

Current (overload protection) Settings, do not change after the current knob.

(6)

Take off a short line, can enter working condition.

3. Constant voltage/current characteristics

This series of the power supply characteristics of constant is called the voltage/current, it can

automatic conversion model with constant voltage change of load in with constant current

condition of constant voltage between successive changes, with constant current intersection

between normal moveout called. For example, if the power load working in constant pressure

mode, stable output voltage. As the load decreases, output voltage will remain stable, until it

reaches pre-set limit flow value. To be worth, maintain stable output current, voltage output as

load increases proportional to further reduce, constant voltage and current of the conversion from

the front panel LED indicator. Similar to the constant current constant voltage from the automatic

conversion is reduced with the load. Constant voltage, current CV indicator when CC indicator.

4. Operating methods

Will the power switch in "OFF" position.

Ensure input voltage correct.

When the power is connected.

Will the power switch ON the "ON" position.

Set the output voltage values to work and Set the output required load current value, Please

adjust "VOLTAGE" and "CURRENT" knob.

Connects the load to Positive "+" terminals and Negative "-" terminals.

When used in ripple and noise higher requirements, output "+" and "-" terminals must have a

reliable connection with GND terminals, this can reduce output ripple and noise.

Maintenance

Fuse replaced

If the fuse burning, voltage or current indicator goes out, the power to stop working,

besides problems generally fuse box, do not open to identify and correct fuse burned,

and then use the same value of the fuse.

INSTALLATION AND USE AND MAINTENANCE

INSTRUCTIONS

This company produces the power used for the contemporary world advanced technical

achievement, after careful thermal design and structure optimization and become a unique

multiterminal function device. Due to the function of the device, series and varieties, its function

is maths and physical properties and each different, so in the installation and use of many

specialized in the note, the explanation:

After open packing machine, please check carefully whether specifications and test report or

carry with specifications conform with the order, the contract if required. If not, please

contact with our sales department, the way to properly handle.

As the first step before use, must be the metal shell reliable power grounding to ensure the

safe, but do not mistake will meet in neutral Shell.

In the installation, please complete electricity run again before each examination and

proofreading terminals, confirm the input and output, AC and DC, positive and negative,

voltage and current, no doubt, eliminate such right after the fault phenomena.

Power does not allow for a long time in full load status, please send full load rate of

regulated dc power supply control in 60%, within the switch power supply load rate control

in 80% within, otherwise will likely cause of the failure of early human. According to the

actual working order should be set aside by current surplus.

To achieve full scattered heat effect, Power should be installed on the air convection

condition good position. General power work should have a good ventilation. In addition, in

the upper crust power does not allow other objects placed.

This power is applicable to resistance of load, if need to let in Capacitive load Inductive load,

should give priority to the load in advance in order to illustrate the contract, if by oversight

will load property shall be timely and correctly, contact the company sales, to seek the offset

schemes Properly.

For high voltage power supply, it is necessary to safety. Use process and the blackout after

10 minutes, do not touch pressure apparatus.

If power failure, should take the most efficient way to taste deliery to the fault, the company

will depending on the situation is different, or repair or replacement. Users must not without

disassembly of power, otherwise will force to our company for analysis of failure caused

difficulties and make judgment work both suffered a new loss.
