The use of high-frequency switching power supply:

1, high-frequency switching power supply in the installation and commissioning as well as the operation process to ensure that the metal shell power line and shell generally connected to the ground, must be reliably grounded, do not mistakenly connect the shell to the zero line;;

2, in the installation is completed before the trial run, please check and proofread the connection on the terminals again, sure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values, etc. correct without doubt, before powering on and running;;

3, to ensure the stability of the equipment must ensure good ventilation conditions;

4, high-frequency switching power supply in the plating production line before access please confirm whether the current and voltage used and the power corresponding to the production line.

High-frequency switching power supply daily maintenance and precautions:

A. Daily inspection (regular inspection)

When the power is running without going to the outer cover, visually check the operation of the power supply from the outside to confirm that there are no abnormalities. Usually check the following points:

1, operating performance in line with standard process specifications.

2, the surrounding environment in line with the standard specifications (see the table of use environment).

3、The panel meter shows that each function switch is normal.

4、No abnormal noise, vibration and smell.

5, the fan is normal operation.

6, no overheating or discoloration and other abnormal conditions.

7, whether the input voltage is in the normal operating range.

8, whether the connection line joints are tight.

Second, attention

1, water-cooled machine into the water, water connection is correct, the water intake is greater than 5Pa, otherwise the temperature inside the machine is too high, the machine can not work properly.

2, water-cooled machine water switch should be installed in the water inlet, water smoothly, the water outlet can not be blocked, otherwise it is easy to cause the machine internal pipe crack.

3, water-cooled machine to confirm that the waterway is smooth before closing the air switch on the host.

4, air-cooled machine due to the use of harsh environments, equipment after a period of time, the surface of the aluminum radiator will have chemical deposits and dust accumulation. If too much buildup, it will affect the heat dissipation of the equipment, resulting in instability of the equipment, which can cause damage to the equipment in serious cases. Therefore, the side panel of the chassis should be opened regularly (interval should not exceed once every three months) to clean and dust the inside of the chassis. Ensure the smooth flow of air, so that the heat in the chassis smoothly distributed to extend the service life of the equipment.

Zhiyi Tips:

Please pay attention to the relevant regulations during the use of high-frequency switching power supply, do not violate and do not exceed the conditions of use of the equipment and the use of norms, in the process of use should strengthen the use of equipment management, daily maintenance, to ensure the stability of the equipment. In the event of equipment failure, professional maintenance personnel should be notified in a timely manner for equipment inspection and repair, in the factory can not be resolved, should promptly contact the manufacturer for maintenance.
