Germany sunshine battery 12V-200AH offer 12V200AH Germany sunshine battery maintenance: Carefully inspect each UPS power drive components and printed circuit boards, should pay special attention to look at the components: electrolytic capacitors: check for leaks, "roof collapse" and expansion or the like phenomenon transformer coil and connecting parts and chokes: Check for overheating discoloration and delamination shedding phenomena, and to make sure that all power cables are securely fastened connection end connection. Cables and Terminals: Check the cable sheath is Cracked, the dregs, scratches and breakage. Check all plug located on the printed circuit board is in contact on a solid and reliable cable connection between the plates without exception. Check all power fuse soundness and are securely installed. Printed circuit board: check whether the abnormal phenomenon so the integrity of the circuit board cleanliness and circuit Check the bypass, rectifier and inverter control power supply board original device. If there is any sign of deterioration or functional deterioration, you should replace the circuit board or make the necessary repairs. Cleaning the components inside the UPS with a vacuum cleaner or with a low pressure air stream to provide a blower to remove any foreign debris and dust. Restore power, according to normal handling step, the UPS switches to the inverter power supply channel. If possible the UPS input distribution cabinet located in the mains input switch is opened, the UPS backup time put the tape running down to check whether the battery pack in the designated range. When the terminal voltage of the battery drops to 40--50V higher than the critical shutdown when the battery voltage, and immediately closed the mains input switch (when the battery terminal voltage drops to its preset low battery voltage is too low voltage automatic shutdown value, UPS inverter power supply, while the rest, automatically transfers the load to the bypass AC supply channel. This test is used to detect the actual backup time battery pack .. (4) maintenance problems with us recommends that users should regularly check all the input and output power cables and connections are used. However, before you perform these checks, require a total blackout UPS power supply system in the state. To select the appropriate time, but in general this is completely blackout Maintenance distance of time should not exceed 2--3 years is appropriate (5) battery maintenance in general, the UPS batteries are mostly used in valve-sealed maintenance-free battery therefore, is limited to ensure maintenance of the battery. battery operating temperature is controlled at 20 ℃ -25 ℃ and in a clean and dry working environment. At present China's civilian and distribution lines are basically three-phase five-wire system, which is the phase line L1 / L2 / L3 + zero Line N + ground G, the device is generally connected to single-phase phase L + N + ground zero line G. standard three-phase voltage 380V, single-phase voltage standard 220V. 10kV grid through step-down transformer to 380V, while the secondary of the transformer of grounding leads zero line N, in order to prevent leakage threat to personal safety, general additionally provided as a separate protective earth ground wire G (also labeled PE), the public electricity network, often three-phase load, also connected with a large number of single-phase loads. So why the zero line after disconnection of power supply lines can cause high voltage single phase load input? Here with a single-phase 3kVA UPS apply in the case of a county bank analysis, shown in Figure 1. When When the three-phase unbalanced load distribution, if the zero line position off in the drawing, analyze this case applied to the respective single-phase load voltage. When the zero line is disconnected, the power supply of the equivalent circuit shown in 2 The figure, added to the load A and UPS voltage (AB point) is 380V, the voltage across the load A and UPS respectively UAC = 19V, UBC = 361V calculated results are input voltage UPS is 361V, this time has been far higher than the rated working voltage of 220V, if the load is not protected by the UPS or UPS protection is not perfect, the consequences can be imagined 12V200AH Germany sunshine battery technology: Germany sunshine series VRLA gel batteries introduction Germany advanced gel battery production technology, the key raw materials imported from Europe, the use of European imports of production equipment for the production of key flooded design, thick plate technology and unique gel electrolyte formulation process to ensure irrigation increase battery life; having long service life and high reliability, can be applied to the harsh high temperature environment, poor power conditions. The products are widely used in telecommunications, electricity, energy storage, UPS / EPS, and other fields. Germany sun gel (A400 Series Description; battery is fixed in the colloid electrolyte sealed VRLA rechargeable battery. Colloid technology invented and developed by the German company sunlight. To achieve a maintenance-free battery. It is the analysis of gas low, durable, 12-year design life, its high degree of reliability.
