风力资源（Wind resource） 1 Chinese wind energy resource reserves and distribution transformer JMB-100VA lighting lamp transformer [product description] JMB lamp power transformer is used with the outer low-voltage safety lamp lighting, mainly used in industrial and mining enterprises. Can choose 220V or 380V power supply [features] long life, energy saving, low temperature rise process [beautiful. Specifications] model: JMB-100 size: 100VA (80W) weight: 3.6 (KG) input voltage: 0V 220V 380V OV 6.3V 12V 24V output voltage: 36V (output voltage can be arbitrarily selected, also can be customized according to customer needs) rated current: 1.4A [1] the use of the environment, the ambient air temperature is -5 DEG to +40 DEG C 24 hours, the average value of not more than +35 DEG C; 2, the installation site altitude less than 2000m; 3, the atmospheric relative humidity in the ambient air temperature is +40... Line lamp transformer input 380V, 220V 36V, 24V, 12V file. 100W about 100 yuan. In the case of 100W, a 3A 50v/2200 F full bridge rectifier, DC filter capacitor can be turned into 34v. Note: output power line lamp transformer is to output current at 36V rated current: 100w/36=2.8A, In the 24V output only: 24v*2.8A=67w output power, power is burned beyond this, 0V - 24V winding. Similarly, the output power for double lamp transformer of the input file is based on the input current at 380V rated current: 100/380=0.26A, In the 220V input only: 220v*0.26A=58W output power, this power is burned beyond, 220V winding. For other lamp transformer power calculation method by analogy. As for the control of transformer, then the output is the main 127V account for a large proportion of 36V lighting and 24V of each separate winding output power is generally not more than 50W (including the control transformer above 300W), therefore, unless the use of ordinary machine tools, control transformer waste power reserves big, generally do not use. The misuse of words, in the output power has n
