The Rx24 resistor must be installed with a heat absorption plate according to the following dimensions when operating under its rated power (units: mm).
(RXresistor power ratings are to bemounted with the following heat sink):
RX247.5W/12.5W:102×152×51×1mm(832cm)
RX2425W:127×178×51×1mm(1077cm³)
RX2450W:305×305×1.5mm(1877cm)
RX100W/250W:305×305×3.2mm(1896cm³)
RX2475W:305×305×1.5mm(1877 cm)
RX24150W:305×305×3.2mm(1896 cm²) RX24300W:3750cm²×3.2mm
Power consumption reduction curve Environmental temperature and power consumption reduction curve 
The power consumption reduction curve graph for the RX24 resistor when the ambient temperature exceeds 25℃. (Derating is required for ambient temperatures above 25,see the following graph.)
The A.B.C curve is applicable to the power reduction curve of RE resistors without thermal absorption plates installed. (Curves A,B.C apply to operation of unmounted resistors;)
The D curve is applicable to all power reduction curves for installing heat absorption plates with RE resistors.
(CurvesD applies to all types mounted with the specified heat sink.) A: RX247.5W/12.5W when not installed (unmounted).
B: When the RX2475W resistor is not installed.
C:RE24150W; When the 300W resistor is not installed.
D: Install on the recommended heat absorption plate.
(D:mounted with recommended aluminum heat sink.)
The power reduction curve of the heat absorption plate Reduce the power consumption curve of the heat absorption plate 
When the area of the recommended heat absorption plate for installation is reduced, the resistor needs to operate at a lower power consumption level.
(Derating is also required when recommended heat sink area is reduced.)
