1.Blown fuse Normally, blown fuses indicate that there is a problem with the internal circuit of the  switching power supply . Because the power supply works in the state of high voltage and high current, the fluctuation and surge of the grid voltage will cause the instantaneous increase of the current in the power supply and cause the blown to fuse. Emphasis should be placed on checking rectifier diodes, high voltage filter electrolytic capacitors, inverted power switches, etc. at the input end of the power supply, and checking whether the components have breakdown, open circuit, damage, etc. If the blown is indeed fused, we should first look at the various components on the circuit board to see whether the appearance of these components has been burned, whether there is an electrolyte overflow, if the above are not found, then use a multimeter to measure the breakdown short circuit of the switch tube. Special attention should be paid to the fact that when a component is...

Some people may find that their  inverters  display 15.3 degrees of power today, but only 14.5 degrees on the meter. A little difference in a day, accumulated over time, that’s a lot! So is the meter installed by the power supply company deliberately slowing it down? Of course not. Now let’s explain to you. There are two main reasons: 1.Causes of line loss: As the heart of photovoltaic, all DC power must be processed to 220V AC power, and then transmitted to the grid through the meter. Then it means that there is a line between the  solar inverter  and the meter. If there is a line, there must be loss. The size of the loss depends on the length of the line and the specifications of the wire, so it’s normal to make a little difference every day. But if there are many differences, it must be a problem. 2.The measurement problem: not that they measure differently, but the accuracy is not the same. Generally speaking, at present, the precision of our single-phas...

Outdoor integrated cabinets  are mainly used in the communications industry. The main raw materials for  outdoor cabinets  are sheet metal. Here is a detailed introduction of why we choose sheet metal as raw material for outdoor cabinets. Outdoor integrated cabinet generally includes shell, bracket, various switches on panel, indicator lamp, etc. The shell is made of steel plate and plastic, with high hardness. It mainly protects the internal components of outdoor cabinet. The bracket is mainly used for fixing the motherboard, power supply and various drivers. Appearance and material are the most basic characteristics of a cabinet. Appearance directly determines whether a cabinet can be accepted by users. Therefore, the current appearance gradually tends to diversify, so it also occupies a certain proportion in our testing. Material mainly depends on the material used in the cabinet. Whether the edges are curled or not, the quality of the material also directly a...

1.The power of  UPS  generally refers to the output power. The input power is bigger than the rated power, especially when the battery has discharged after a period of power stopping. The input rectifier not only supplies power to the load, but also charges the battery. The maximum current can reach 1.3 times of the rated current. If the battery pack capacity is particularly large, and the host is equipped with a charging module, the current will be greater. 2.UPS itself is a kind of non-linear load, which will produce some harmonic current feedback to the input grid, and will increase the temperature of the generator ball. If the generator load ratio is too high, it may burn the ball. 3.The load behind UPS to the generator is all selected by the internal circuit of  on grid UPS  to be battery or city power/power generation. It is one-time loading. There is no soft start or other way. If UPS is loaded at 80% load and the impulse current is calculated at thre...
