K-factor isolation transformer product overview:

Weihao K-factor safety isolation transformer is produced by Dongwen Transformer Co., Ltd. using high-quality materials and advanced technology for many years. It has the advantages of moisture-proof, convenient maintenance, etc. It can penetrate deep into the load center and can be used for import and export equipment, professionally supporting subways, airports, high-rise buildings, stations, wharves, enterprises and tunnels and other power transmission and distribution places. The K13 coefficient is a general special measure of the harmonic heating effect, especially for the harmonics on the transformer. It not only emphasizes the harmonic frequency, but also emphasizes the harmonic order, harmonic spectrum distribution and spectrum ratio. The K-factor isolation transformer is mainly used for When a large amount of nonlinear load is required. Designed according to the American UL1561 standard, there are K4, K9, K13, K20, K30, K40, K50 and other coefficients. K-13 is a common load for office loads and general computer room loads, K-20 tends to be dedicated computer loads (precision air conditioners and precision motors) and power quality sensitive equipment PDUs (power distribution units). The K coefficient isolation transformer is mainly used in various power supply places with AC 50-60Hz and voltage not exceeding 3300V, and the distribution of various input and output voltages, connection groups, and tap line group capacity of products can be carefully designed according to user requirements. with manufacturing.
