PRODUCT DESCRIPTION

DESCRIPTION OF TPR3005T-3C

This is double-channel regulated DC power supply with a back-light LCD panel.The voltage and current can be adjusted continuously with Knobs that are hidden behind a panel to provent accidental movement.Two channels-canbe run series,parallel function or independently from each other.CH3 is a fixed output with three settings 2.5V,3.3V and 5V.They are used in product research departments,laboratories,electronic production lines,and also in the communications industry.

limiting Current Settings:

limiting Current set operation method are as follows

The decision to power instrument maximum safety.

Rotating voltage control knob, until the CC designator light.

Adjust current knob to the current needs

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

Take off a short line, can enter working condition.

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.

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.
