Ohmite’s TAP800 Series dissi-

pates 800 watts of power when

used with a liquid or air cooled

heat sink system. The TAP800

rounds out 600 watt (TAP600)

and 1000 watt (TAP1000)

product offerings. Applications

include variable speed drives,

power supplies, robotics, motor

control, control devices, and

other power designs.
