Sanmenxia with computers UPS power supply, how much money

Sanmenxia with computers UPS power supply, how much money Zhengzhou Tiger Electronics Co., Ltd. 0371-63661728 158900528762) Never with inductive loads, such as cash registers, fluorescent lights, air conditioners and other damage caused by the use of advanced DSP digital control technology of DSP digital application control technology, more stable performance of the UPS, quality is more superior. Load power factor of 0.8 for the development trend of electrical equipment, with a capacity to carry more. Active input power factor correction (PFC) Using digital control of active power factor correction technology, the input power factor above 0.98, in order to avoid contamination of the environment on the grid to save energy, reduce investment costs of the system. This product is environment-friendly green products, in line with the requirements of EU environmental directives RoHS and the National Electronic Information Products Pollution Control Regulations, the product under normal use will not cause harm to humans and the environment. Wide input voltage and frequency range is extremely wide input voltage and frequency range, even in very poor power environment of the normal power supply in remote areas can reduce the number of battery discharge, improved battery life. Can be used with generators Wide range of input voltage and frequency range, can effectively isolate the adverse power generator for the load to provide clean, safe and stable power supply. Zero switching Mains unstable, UPS power supply mode conversion time is zero, effectively ensuring the safety and reliability of the load operation. Powerful extensibility features Smart slot can provide a wealth of scalable features, you can choose to install Winpower CMC monitoring card, SNMP card, RS485, AS400 card, EMD environmental monitor. Note: 1) UPS should be noted that the use of a well-ventilated environment, conducive to heat, and keep the environment clean. 2) Never with inductive loads, such as cash registers, fluorescent lights, air conditioning, etc., to avoid damage. 3) UPS output load control at around 60% for the best, highest reliability. 4) UPS load is too light (such as a 1000VA UPS with 100VA load) may cause the battery depth of discharge will reduce battery life, should be avoided. 5) appropriate discharge, helps activate the battery, such as long-term non-stop electricity, every three months to be artificially broken mains load and discharge time with the UPS, which can extend the battery life. 6) For most small UPS, work reopen UPS, boot to avoid load start, should work to close UPS; for network room UPS, because most network is 24 hours, so the UPS must run around the clock. 7) UPS should be promptly charged after discharge to avoid battery damage due to excessive self-discharge. Reasons to buy a mains instability: the mains system as a public power grid, especially near large factories exist, large inductive, capacitive, switching power supplies and other loads often cause mains voltage waveform distortion or frequency drift. 2, unexpected power failure is inevitable: lightning, power transmission systems open or short circuit, power supply error and other unexpected loss of power plug to a PC, printer, scanner and other sophisticated electronic devices greatly damage, such as a hard scratch. 3, PC and other stringent power requirements: PC power supply is a rectifier power supply, high voltage rectifier can cause burning. The voltage spikes and transient over-voltage and power noise and other interference may enter through the rectifier board, affecting the normal operation of the machine, even burned the host line. 4. The cost of risk reduction: With the increasing use of computers, and computer-related equipment have also entered many people's lives, UPS prices are getting cheaper, with investment of 300 yuan 6000 yuan protection equipment why not quickly action? Information to buy UPS in accordance with its working methods can be divided into reserve, on-line and line-interactive. Wherein the back-UPS because technology is mature, low cost, the price is also relatively inexpensive, it is suitable for home use. Back-UPS, also known as off-line (off line), there are Back or Back up, Standy by words such as general are back-up UPS. 2KVA capacity is generally less, they use a 12VDC / 7AH a battery or two, the push-pull work, frequency step-up transformer, relay switching. In principle, back-up UPS with the main difference is that the on-line UPS: UPS back-up when there is electricity only mains power regulator, the inverter does not work, in a wait state, when abnormal electricity, reserve UPS is quickly switched to the inverter status, battery power will become AC inverters continue to supply the load, so the back-up UPS when mains turn against the work there will be a transition time, usually 4ms, (20ms or less power is not It will affect PC). Low price, small size, simple operation make back-up UPS became the first choice of home. As a protective power equipment, UPS usually note purchase power, voltage range, power supply time, power efficiency, conversion time and other technical parameters, but also to grasp the author recommends the following principles: 1, brand: Compare the current market Good brands include Hills UPS, APC, Delta and so on, these brands better product quality, service is also good. When buying UPS, be sure to choose a regular, reputable dealers, the best go to a special UPS dealer or reseller, try to avoid being taken. 2, focusing on weight; the same with the PC power supply, good access to UPS size and weight is not too large, due to the current transformer and the battery manufacturing technology has not been much of a breakthrough, a good quality UPS necessarily have a certain volume and weight. 3, focusing on testing: performance as in the purchase of the field test of the product. Such as man-made power supply measurement time by reducing the voltage regulator and other equipment can measure the output voltage regulation and so on. 4, concerned about additional functions: If the price is acceptable, then may wish to consider a more useful additional features, such as some UPS not only to the PC provides power protection, but also to use its own configurable RJ45 / RJ11 port, the network cable or the Internet Modem used to provide surge protection.
