Power dissipation is 1100 W by using a water cooled heatsink at Twater = 15 °C of Rth = 0.059 °C/W (25 °C to the nearest point of the resistor
onto heatsink) and Rth contact estimated at 0.07 °C/W.

RECOMMENDATIONS FOR MOUNTING ONTO A HEATSINK
• Surfaces in contact must be carefully cleaned.
• The heatsink must have an acceptable flatness: From 0.05 mm to 0.1 mm/100 mm.
• Roughness of the heatsink must be around 6.3 μm. In order to improve thermal conductivity, surfaces in contact (ceramic,
heatsink) should be coated with a silicone grease (type SI 340 from Blue Star Silicones). Thermal film (type Q-pad II from
Berquist) is also possible, easier and faster to install than grease but with a lower efficiency for the power dissipation.
• The fastening of the resistor to the heatsink is under pressure control of two screws tightened at 2 Nm for full power
availability.

• The following accessories are supplied with each product:
- 2 screws CHC M4 x 25 class 8.8 and 2 M4 contact lock washers for heatsink mounting
- 2 screws TH M4 x 6/6 and 2 M4 contact lock washers for connections. 2 off CHC M4 x 16/16 class 8
CHOICE OF THE HEATSINK AND THE THERMAL INTERFACE
The user must choose the heatsink according to the working conditions of the component (power, room temperature).
Maximum working temperature must not exceed 200 °C. The dissipated power is simply calculated by the following ratio:
T
---------------------------------------------------------------------------------------------
P =
Rth (j - c) + Rth (c - h) + Rth (h - a)
P:
Expressed in W
T:
Difference between maximum working temperature and room temperature or fluid cooling temperature.
Rth (j - c)
:
Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal
resistance of the component: 0.039 °C/W.
R
R
th (c - h): Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the
thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device.
th (h - a): Thermal resistance of the heatsink.
Examꢁle:
Rth (c - h) + Rth (h - a) for LPS 1100 power dissipation 850 W at + 18 °C fluid temperature.

POWER RATING
In any case the applied voltage must be lower than
The temperature of the case should be maintained within
the limit specified in the following figure. To optimize
the thermal conduction, contacting surfaces should be
coated with silicone grease or thermal film, and heatsink
mounting screws tightened to 2 Nm.
UI = 6600 V.
Short time overload: 2 x Pr/10 s for heatsink with
Rth(h-a) 0.26 °C/W (maximum power: 700 W) and 1.6 x
