Series
Water Cooled High Power Resistor
FEATURES
ƒ Small size 500W, 1Kw, and 2Kw water-cooled non-inductive
resistor with very low resistor temperature while in operation
ƒ Flat plate resistance and twisted pair leads and special terminal
structure (patent) have shown excellent surge absorption
performance
ƒ Resistors are insulated from case by high purity alumina
substrate, and are guaranteed voltage-proof to 5kV
APPLICATIONS
ƒ Surge suppression resistors for power thyristors and IGBT,
ƒ Power supply for electric power conversion system and
industrial apparatus
ƒ High output AC motor controls
