DC 5521 5525 Power Cable Male to Female Connector
Description
The performance parameters of the DC5521 power cord are as follows:
Interface size:
The outer diameter of the plug is 5.5 mm, which is the outer diameter of the power cord plug to ensure that it can accurately match and be inserted into the corresponding DC5521 socket or interface.
The inner diameter of the plug is 2.1 mm, which is the diameter of the internal metal contact part of the plug, and this size is very important for the stability of current transmission and the reliability of contact.
Wire specification:
Wire diameter: Common wire diameters include 0.5 mm², 0.75 mm², 1.2 mm², etc. The larger the wire diameter, the greater the current that the power cord can withstand and can support larger power equipment; conversely, power cords with a smaller wire diameter are suitable for equipment with less power.
Core number: Generally, it is a double-core wire, which is used for the transmission of positive and negative currents respectively to ensure the normal flow of current.
Material: The material of the wire is mostly copper, which has good electrical conductivity and thermal conductivity, which can ensure the efficiency and stability of current transmission. The pins of some products may be made of gold plating or other conductive materials to improve contact performance and oxidation resistance.
Rated current: According to different usage scenarios and equipment requirements, the rated current of the DC5521 power cord is different, and common ones are 5A, 7.5A, 12A, etc. When using it, it should be ensured that the working current of the connected equipment does not exceed the rated current of the power cord to ensure safe and stable power supply.
Length: The length of the DC5521 power cord has a variety of options, ranging from several tens of centimeters to several meters. Users can choose the appropriate length of the power cord according to the needs of the actual usage scenario. For example, in a limited space environment, a shorter power cord can be selected, and for equipment that needs to be connected over a long distance, a longer power cord needs to be selected.
Insulation performance:
Insulation material: Usually, insulating materials such as PVC (polyvinyl chloride) are used, which have good insulation performance and wear resistance, and can effectively prevent short circuits between wires and the impact of the external environment on wires.
Insulation resistance: Generally, a higher insulation resistance is required to ensure that the current is transmitted inside the wire without leaking to the external environment to ensure the safety of use.
Application
The DC5521 power cord has a wide range of application fields, mainly including the following aspects:
In the field of electronic equipment:
Routers and switches: These network devices usually require DC power supply, and the DC5521 power cord can stably provide power support for them, ensuring the normal operation and continuous work of network devices and ensuring the stable connection of the network.
