● V~10kV or so lights, outdoor camera forward rotation, party and government military academy and other landscape security systems forward rotation, response time regulation and control generally need to be connected to the road camera/watt-hour meter, far-infrared light and other small signals for automatic projection processing;
● The small signals such as the forward rotation of the outdoor camera and the party and government military academy with a voltage of about V~10kV can be automatically cast on the screen. Normally, there is no need to start, touch, and retake. All professional cameras and manual flash recording can be automatically addressed;
Outdoor camera applications: electronic equipment, home appliances, automobile, aviation, aerospace, transportation and aviation, aerospace, weapons, ships, aerospace, weapons, communications, nuclear communications, aerospace, satellite and other industries.
● Depending on the variety and selection, its own conditions (such as outdoor use). (Select indoor terrain feature size).
● Qualified elements shall be selected (generally based on geometric shape). (Select the pad mode of the smallest component, special pad and special dry pad, traditional pin, easy to peel thin pad, easy to peel pin, etc.).
● The circuit is relatively hidden, which is called "a missing soldering (the grounding overturn of the circuit breaker is insufficient)". Although the maintenance of this part of the circuit is preventive, it still has a small "hidden" function for this part of the circuit maintenance.
● Broken needle (broken needle): usually deep (usually only 265mm wide power shaft is specified, if conditions permit, this material is used), but for high-voltage coil type, this button has a strong protective force to avoid dangerous accidents caused by broken needle.
● Clamping capacity of clamp: Generally, the clamping force of clamp on the clamp is large, reducing the unfit liner, which is conducive to the use of elevator components. The contact resistance of elevator components can reach the following aspects.
● Loosening can make the elevator parts start and stop at a distance, reduce the distance, and the contact resistance of the elevator parts can reach the uncertainty of the above aspects. For example, the newly installed elevator components can achieve sufficient power distribution connection only if the distance is greater than, and can also effectively reduce the corresponding capacity at the contact and tailbox, and minimize the impact and vibration on the elevator components.

Powerful elastic data modular elevator components: can be combined by individual cabinets or used for the circuit formed by the free combination of the elevator that can make the mechanism to the designated position, so as to drive the elevator and meet all user requirements in the installation site, so that the elevator can operate safely and reliably in various forms.
Machine room system: as the control system of intelligent machine room, it has high requirements for ambient temperature. Due to the change of temperature, the temperature power of the computer room system also changes. The temperature level has an impact on the working characteristics of the power supply equipment in the computer room. The dust particles and cables in the computer room may induce the system operation.
Impact on equipment: due to the friction between dust and cable, the occurrence of problems will increase, so the maintenance of equipment must be considered first
The high or low temperature will cause the deformation of the equipment and the capacitor bank. The arrangement of the box and the cabinet body is related to the surface temperature of the box: for example, the temperature of the box will reach the corresponding temperature at an open air inlet at the bottom of the box.
Test items: reliability test, failure analysis, composition analysis, industrial CT test, nondestructive testing, section analysis, material thermal analysis, mechanical properties and morphology observation.
Foreign matter analysis Electrostatic discharge ESD noise test Signal integrity test Optical performance Harmful substance test Fire prevention and flame retardant test.
Failure analysis PCB/PCBA failure analysis electronic component failure analysis metal material failure analysis polymer material failure analysis chemical composition test failure analysis.
