TAP2000 Series Ultra High Power Planar Resistor 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.

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.
