Output

 

Over   power

110%-180% OFF

Test   method: Increase the output current until protection. When protection, it can   not cause fire, smoke, electric shock and other dangerous phenomena. It can   recover automatically after eliminating overpower.

28.8-33.6V  

32.2-36.4

41.4-46.8V

55.2-64.8V

Test   method: Pin 1-3 of short circuit U2; Protection mode: constant voltage. It   can not cause fire, smoke, electric shock and other dangerous phenomenon. It   can return to normal after eliminating over voltage. Note: Do not use the   external voltage to test.

Over   current

120%-180%

Test   method: The overcurrent point is the current value of the output current   increasing until the output voltage falls out of the stable voltage accuracy   range. When protection, it can not cause fire, smoke, electric shock and   other dangerous phenomena. After eliminating overcurrent, it can   automatically resume to normal.

Short   circuit

The   copper wire with sufficient cross-sectional area and length of 15cm± 5cm is   used to short-circuit directly at the output port of the power supply, which   can be short-circuit for long time. After eliminating short-circuit, it can   be automatically restored

Instructions for installation and use: 

1.During installation, please follow the above instructions for installation.

2.Before the installation is complete, please check and proofread the wiring on each terminal, make sure that input and output, AC and DC, positive and negative terminals, voltage and current values are correct, prevent the occurrence of reverse connection error, to avoid damage to the power supply and equipment.

3.Please use a multimeter to measure whether the live wire, neutral wire and ground wire are short-circuited and whether the output terminal is short-circuited before power-on.It is best to start no-load when energized.

4.Do not exceed the nominal value of the power supply, so as not to affect the reliability of the product.If you need to change the output parameters of the power supply, please consult the technical department of our company before using the power supply to ensure the use effect and reliability.

5.In order to ensure the safety of use and reduce interference, please ensure that the grounding terminal is reliably grounded (grounding wire greater than AWG18#.

6.In order to extend the life of the power supply, we can provide air duct design solutions.

7.Do not switch the power supply frequently, otherwise it will affect its life.

8.If the power supply fails, please do not repair it without permission. Please contact the customer service Department of our company as soon as possible.


Packing, transportation and storage:

1.Packaging: The product name, model, manufacturer's logo, manufacturer's quality department inspection certificate, manufacturing date, etc., shall be marked on the packing box.

2.Transportation: The packaging is suitable for transportation by car, ship, plane, train, etc. During transportation, it should be rainproof and loaded and unloaded in a civilized manner.

3.Storage: the product is not used should be placed in the packing box, storage environment temperature and relative humidity should meet the requirements of the product, there should be no corrosive gas or products in the warehouse, and no strong mechanical vibration, impact and strong magnetic field.The packing case should be padded at least 20cm above the ground and protected from water.If the storage time is too long (more than 1 year), it should be re-inspected by professional personnel before use.
