Ultra High Voltage Ceramic Power Resistor
TYPE IX - INDIRECT WATER COOLING
The IX resistor is designed to be indirectly cooled with water running through the water-cooled block assembled on both sides of the resistors. In view of the current trend to exploit the large power circuits with semiconductors, demands are increasingly getting higher for non-inductive resistors with a compact design but a large energy capacity. IX resistors connected in series or in parallel will comply with the requirements on the voltage and current load.
