DDDL-380-5 three-phase voltage and current source is a test product developed by our company. It combines the advantages of similar products at home and abroad, uses numerical control technology, has strong anti-interference ability, and is compared with the previous generation of current current. Because of the use of low power, large capacity autotransformer and high guide magnet core converter, The utility model has the advantages of large power, small volume and light weight. It is mainly used for thermal relays, motor protectors, contactors, circuit breakers, air switches, switchgear, protective screen calibration.

major function

0 ~ 5000V*3 voltage can be output for a long time

At the same time, it can connect several serial checks to improve efficiency.

A beautiful and generous PVC panel

High measurement precision

High power, small volume, and strong load capacity

Small size, light weight, only 30% to 70% of the volume of similar products.

Operational aspects

(1) after the connection is completed, check it again to see if there is any wiring error and whether the connector is in good contact.

(2) during the testing process, if there is fire, and no indication is displayed when starting, the power supply should be shut down immediately.

Check connection

(3) in actual wiring, the current output terminal should form a loop, otherwise there will be no current output.

This lift is equipped with a random output wire and the output copper wire is selected according to 10A/mm2.

(5) the capacity of the equipment is designed according to the 5 minute short time operation, for example, the batch test should be less than 2.5 minutes.

Clock, wait for 10 minutes, then do the next work. If the temperature rise (30 minutes -24 hours) should be according to length

Time work temperature rise configuration

Three operation description

1. before the power supply is connected, the power switch should be disconnected first, and all the handles are turned back to zero position counterclockwise.

2. the power input terminal is connected with the AC380V three-phase four wire voltage, and then the sample is connected to the corresponding voltage and the current output terminal.

3. after the connection is completed, close the "power switch" and press the "start" button to adjust the corresponding current and voltage in a clockwise manner. After the end of the experiment, press the "stop" button.

Four safety precautions

1, in order to ensure the safety of operators and instruments, ensure good grounding.

2, when the experiment is ready, it is best to connect the ground wire first, and finally, when the work is finished, remove the ground wire.

3, the power supply of the access instrument can withstand the current impact of 45A.

4, when the instrument is connected with the test product, check whether the wiring is wrong, so as not to cause equipment damage due to wiring errors.

5, the maximum current value of the over-current protection should not exceed the rated output current value of the instrument.

6, no connection can be inserted in the case of power on.

Eight transportation and maintenance

1. transport:

The product must be packed during transportation. The packing box should be wooden box, and foam proof layer should be used in the packing box. Packaged products should not be placed in open-air garage during road, railway and air transportation. The storehouse should pay attention to rain protection, dust prevention and mechanical damage.

2. storage:

The instrument should be stored in an environment of -40 to 60 degrees centigrade with a relative humidity of not more than 85%, ventilated and corrosive free.

It should not be placed only on the ground and walls.

3. dust prevention:

In humid areas or in wet seasons, this instrument is required to open electricity once a month (about two hours) to protect the electronic components, if it is not used for a long time.
