Function of pure sine wave inverter

Inverter output function:
Open the inverter switch in the front of the panel, the inverter is about to change the DC power of the battery into pure sine wave alternating current, output by the ACOUTPUT of the rear panel.
Automatic voltage stabilizing function:
When the battery voltage is fluctuated between the undervoltage and the overvoltage, and the load is changed in the rated power, the device can
automatically output voltage.
Overvoltage protection function:
When the battery voltage is greater than the overvoltage, the device will automatically cut off the inverter output, the front LCD panel display “overpressure”, the alarm sound and the buzzer sends out ten seconds. When the voltage is down to “overvoltage recovery point”, the inversion recovery work.
Undervoltage protection function:
When the battery voltage is lower than the “undervoltage point”, in order to avoid excessive discharge to damage the battery, the device will automatically cut off the output. At this time, the front panel LCD display “undervoltage”, and the buzzer alarm sound ten seconds. When the voltage is up to the “undervoltage recovery point”, the inverter recover to work; if there is a switching device, automatically switch to the city output when undervoltage.
Overload protection function:
If the AC output power exceeds the rated power, the device will automatically cut off the inverter output, the front panel LCD display “overload”, at the same time, the buzzer sends out ten seconds alarm sound. Off the front panel of the “inverter switch”, “overload” display disappeared. If you need to reboot, you must check to confirm the load in the allowable range, and then open the “inverter switch”, to restore the output of the inverter.
Short circuit protection function:
If the short circuit of the AC output circuit, the device will automatically cut off the inverter output, the front panel LCD display “overload”, at the same time, the buzzer alarm ten seconds. Off the “inverter switch” of the front panel, “overload” display disappeared. If you need to reboot, you must check to confirm the output circuit is normal, and then open the “inverter”, to restore the output of the inverter.
Overheating protection function:
If the temperature of the control part of the internal chassis is too high, the device will automatically cut off the inverter output, the front panel LCD display “overheating”, at the same time, the buzzer sends out ten seconds alarm sound. After the temperature is restored to the normal value, the output of the inverter is recovered.
Battery reverse protection function:
If the positive and negative polarity of the battery reversed, the chassis of the fuse will automatically fuse to avoid damage to the battery and equipment. But it is still prohibited to reverse the battery!
The optional city power switching function:
If choose the city power switching function, when the battery undervoltage or inverter failure, the equipment will automatically switch the load to the city power supply, so as to guarantee the stability of the power supply to the system. After the inverter can work normally, it will automatically switch to the inverter power supply.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
