Product Description

Product introduction

   D-R series jack special transformer is suitable for AC circuit frequency 50Hz, as a local lighting power supply for machine tools and other equipment, in line with the standard :Q/ZT 258.
   It is composed of NDK series transformer and protective shell. The shell is provided with terminals for input power and load wiring and ground screws for grounding.

·The altitude of use is not more than 2000m.



·The upper limit of ambient air temperature is 40 ° C, and the lower limit of ambient air temperature is -5 ° C (when the user needs to use it in an environment higher than 40 ° C or lower than -5 ° C, it needs to be specially specified and specially customized when ordering).

·When the maximum temperature is 40 ° C, the relative humidity of the air does not exceed 50%, and a higher relative humidity can be allowed at a lower temperature.
·For example, 90% at 20 ° C, special measures should be taken for occasional condensation due to temperature changes.

 

The ambient air does not contain harmful gases or dust that corrode metal and destroy insulation; In use, the transformer shall not be subjected to water,
Erosion by rain and snow.
