RES-TAP1000-2000 Datasheet, PDF (1/2 Pages) Ohmite Mfg. Co. – High Energy Rating

TAP1000 & 2000
1000 & 2000 Watt Heat Sinkable Planar
The TAP series delivers
1000W or 2000W of contin-
uous power when properly
mounted to a liquid cooled
heat sink (based on 85°C
mounting plate tempera-
ture)
Applications include
power conditioning, power
distribution, power conver-
sion, and power control.
