㈠Features

   Ⅰ A tubular ceramic insulator has a fixed number of windings and is wound with heavy alloy wire as a resistance element.The staggering wound is made according to the desired  resistance value.
   Ⅱ Metal parts are heavily plated to prevent oxidation at high operating temperature and to prevent corrosion. PHK’s high power rating(500w-1000w)and low resistance value(0.5Ω-0.7Ω)provide application high starter power and capacity.

   Ⅲ This power wirewound resistor is high temperature-resistant, dissipates heat well ,has a low temperature coefficient that varies direct in direct proportion, and is suitable for application loads involving brief current surges.

㈡Applications

   ⅠTypical applications for power starter resistors in motor starters , load measurements,            industrial machinery, electric distribution, dynamic braking, load dumping , current limiting,      instrumentation, and automation control installations.

   ⅡDue to the set number of windings on the ceramic form ,the resistance value range is         

     relatively low . Tolerance is ±10% and this product is available in various in resistance boxes.

㈢Power Rating:
    500W,600W,1000W
㈣Tolerance:
    K=±10%

㈤Resistance Range
