Introduction: There are many kinds of air conditioners, but are you familiar with the precision air conditioners in the engine room? Precision air conditioners are the most effective means of ensuring a constant temperature in the equipment room. They can maintain a normal working environment for computers and servers. Once the maintenance of the engine room air conditioning is not in place, it will increase the difficulty of computer operation, so we should cause a high degree of attention. Here's a small series to learn about the precautions of precision air conditioning during maintenance.
First of all, some electronic components of the air-conditioner dedicated to the computer room are exposed to the air, and these electronic components are then contaminated by pollutants in the air, which is what we call carbonization. This will damage the parts. Through practice, we can find that the occurrence of carbonization in Asia is higher than in other regions, so we should pay more attention to this issue. Do not expose the electronic components of the air-conditioner to the air. This will have the effect of maintenance. If it is aging, we must replace the parts in time to ensure the normal use of the dedicated air conditioner in the engine room.
The inspection of the main components consists of three parts, namely the noise associated with the fan inside and outside, or the fan bearings, and whether the shaft is deformed, the fan bearings heat or the operating current conditions. We must pay attention to the noise of the compressor or the operating current and the conditions of heat generation and the corresponding equalization of pressure. Winding over-temperature protection and crankshaft, heater and other related issues are some problems.
At the same time, during the maintenance process, we must also constantly check the condenser fan noise, check the winding resistance, and balance the running current, heating conditions, and pressure. In addition, it is a key factor for us to pay attention to the problems of filter screens and checking whether the supply air ducts are blocked. For compressor-related work performance as well as check winding resistance and over-temperature over-temperature protection, etc., corresponding inspections shall be conducted.
Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
