? In fact, although the manufacturer has the freedom to draw their own nameplate, no one dares to cheat. Because the power supply is sold to consumers, if the consumer because you believe that your "fake" nameplate and the recruit, then touched the most the most the bottom line of business-integrity. (Of course, for the plot to make quick money and disregard the credibility of the cottage manufacturers is another matter) No honest manufacturer, who dares to buy your product? Who da

above the resistor.2. allowable error: the percentage deviation between the nominal resistance value and the actual resistance value and the nominal resistance value, which indicates the accuracy of the resistor.The correspondence between allowable errors and accuracy levels is as follows: ± 0. 5%-0.05, ± 1%-0.1 (or 00), ± 2%-0.2 (or 0), ± 5%-I, ± 10%-II, and ± 20%-III3. Rated Power: the normal atmospheric pressure is 90-106.6kpa and the ambient temp

Generally look at the power supply power We all say is rated power, so everyone in the purchase of power must pay attention to look at the rated power, not the maximum power. Many well-known fake brand power supply, are like in the Power label won a very high power value, but this is only the most high-power, not rated power, to know that the maximum power is the

You can build a virtual private network in countless ways. The minimal VPN implementation scheme consists of the Internet-connected ras pptp server, the Internet-connected client, and the PPTP connection between the above server and the client. As long as the ISP service or Internet connection is available, the client can establish a connection with your server from any corner of the world. However, most VPNs are not only composed of interconnected se

The purpose of testing the UPS power supply is to determine whether the practical technical indicators of UPS can meet the requirements. UPS testing generally includes both steady-state testing and dynamic testing. The steady-state test is performed under no-load, 50% rated load, and 100% rated load conditions, test the phase voltage, line voltage, no-load loss, power factor, efficiency, output voltage wave

Original http://blog.sina.com.cn/s/blog_605538500101bd3p.html 0 Power resistor value RT (Ω) RT refers to the resistance value measured by measuring power that causes the change in the resistance value to be negligible in relation to the total measurement error when the specified temperature T is used. Olympian Sincerity The relationship between resistance value and temperature variation is: RT = RN EXPB (1/t–1/tn) RT: NTC thermistor resistance at temperature T (K).RN: NTC thermistor resistance

In the new installation or to upgrade the hardware for the old computer, we often have to understand the computer power of W. General new installed according to the CPU, video card, memory, hard disk, motherboard power consumption, to calculate the appropriate size power of the power supply, while the old computer upgrade hardware, is mainly to see the upgrade of new hardware to increase the power consumption, on whether the power can also carry the move, if the power consumption is small, then

If I do not deploy IPv6, will it collapse? Will the end of the world come? Will the Internet continue to run? Will enterprise computers crash into a pool of data? The answer is simple: No. At least not yet. However, enterprises may have to consider some things. ISP (Internet Service Providers) will not be stupid to cut off IPv4 access when they start to launch IPv6. If they do this, only a few websites can access the Internet at that time, because mos

panel -- Internet option-connection-LAN Settings-use proxy server for LAN) is set in the browser ), setting the proxy server does not affect QQ's network connection, because QQ uses port 4000 and port 80 or 8080 to access the Internet. This is why many people do not understand why QQ can be accessed, but web pages cannot be opened. The proxy server is generally not very stable, sometimes it can be accessed, sometimes it cannot. If so, cancel the proxy. Iii. DNS server explanation Error The so-c

At present, the power adapter according to the different supporting electronic and electrical equipment, respectively use the national standard "GB4943-2001: information technology equipment safety" and "GB8898-2001: security requirements for audio, video, and similar electronic equipment shall be used as the quality assessment standard. For example, power adapters for laptop computers, cellular phones, and other information equipment shall comply with the requirements of the national standard g

Refer to the following Alpha router configuration method to access and set up a Broadband Router through a browser. After these three steps, you can basically get familiar with this quick installation method. To use this installation method, you must have installed a browser on your workstation and have an ISP account or a fixed valid IP address. If you do not have any of them, you cannot use this installation method. The following describes how to ac

business partners with secure and secure connections through a single network structure;For enterprises, the exists based on the dial-up VPN can enhance contact with users, business partners and suppliers;Telephone companies can use the dial-up VPN service to reduce terminal congestion;By providing secure external remote access services for the company, ISP can increase revenue. through exclusive layering and Related Competition services,

current in the corresponding winding, the electric motor's synthetic magnetic potential only rotates part of the step angle. When subdivided driving, the winding current is not a square wave but a step wave, and the rated current is a step type input or removal. For example, if the current is divided into n steps, it takes n times for the rotor to turn a step angle, that is, n subdivision, as shown in Figure 5. The general subdivision method only ch

First, to understand their own charging treasureThere are generally several data on the charging treasure: battery capacity Capacity (mAh), input current (a), output current (a), input voltage (v), Output voltage (v)The power of the rechargeable battery is mah (mah), which is the product of the current intensity and time, and when the current intensity is in mah (MA) units, the time is measured in hours (h), and the two are multiplied by mah (mah). It represents the time of full discharge under

Power nameplate identification, we can generally determine whether a power supply is not a good power, or in the end suitable for our own platform to use. ▲ The nameplate displayed above a certain power supply Maximum power is peak, rated power is important Rated power, for a power source is very important, only we clearly see the "Rated power" in

distribute the monitoring sites to different places. In fact, it is enough to use the nagios distributed method to do this. However, if you want to do an instant trigger emergency task, even if you click execute immediately on the nagios page, it will take a while to return all the results. Therefore, I chose to write a distributed asynchronous system. The central controller script is as follows: #!/usr/bin/perluse Modern::Perl;use AnyEvent;use AnyEvent::Redis::RipeRedis;use Storable qw/freeze
