td1150 tester for transformer winding thermometers


参考标准: jb/t 8450-2005《变压器用绕组温控器》

可同时输出 / 测量 0 ~ 6 a 的交流电流,准确度为 0.05 



model td1150, an apparatus for testing transformer winding thermometers. meet the requirements of jb/t 8450-2005 thermometers for transformer winding.


this apparatus can continuously output ac current up to 6 a with an accuracy of class 0.05.

 the measurement loop is independent, you can measure the output current of the thermometer up to 6 a when the apparatus is outputting current.

 strong load capacity up to 60 va, can continuously work for 8 hours with a stability of 0.01 % under full load.

 there is an output of dc 24 v, can be used as a power supply for the thermometers with a maximum current output up to 200 ma.
