Series SUP800 High Power Resistor

Short Description:

Mainly used as a snubber resistor to compensate the C-R peaks in traction power supplies. Furthermore for speed drives, power supplies, control devices and robotics. The easy mounting fixture guarantees an auto-calibrated pressure to the cooling plate of about 300 N.

■800W operating power

■Non-Inductive design

■ROHS compliant

■Materials in accordance with UL 94 V-0

Derating (thermal resist.) SUP800: 8.47W/K (0.12 K/W)
Power rating: 800 W at 85°C bottom case temperature
This value is only applicable when using a thermal conduction to the heat sink Rth-cs<0.025K/W. This value can be obtained by using a thermal transfer compound with a heat conductivity of at least 1 W/mK. The flatness of the cooling plate must be better than 0.05 mm overall. Surface roughness should not exceed 6.4 μm.
