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.
