TAP2000 Series Datasheet

Ultra High Power Planar Resistor  

Res Tap2k product image

 

The Ohmite TAP2000 series offers  2000 watts of power dissipation when  properly heatsinked. The design of  the TAP series creates a constant  pressure to the cooling plate of  approximately 300 N for proper thermal flow. The TAP2000 is ideal for  variable speed drives, power supplies,  control devices, robotics, motor control and other power designs

 

Features

  • 2,000 W operating power with proper heatsinking
  • Non-Inductive design
  • ROHS compliant
  • High insulation & partial discharge performance
  • Materials in accordance with UL 94 V-0

THIS PRODUCT IS DESIGNED FOR USE WITH PROPER HEATSINKING.

Maximum base plate temperature of the resistor must be monitored and kept within specified limits to establish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. The Ohmite CP4 (https://www.ohmite.com/cp4-series-chillplate/) is an example of properly designed heat sink.
