COOLING
The temperature of the heatsink may be maintained at the specified values with:
• Forced air ventilation
• Internal circulation of a liquid cooling
• Heatsink contact surface: Ra 6.3 μm
• Evenness defect: 0.05 mm max.
• Surface temperature gradient (isotherm): 20 °C max.
• Thermal compound not supplied (resistance < 0.05 °C/W / 0.025 mm)
The user must select the thermal resistance of the heatsink according to the power applied.
TERMINAL OPTIONS
• Electrical terminals M5
• Other terminal size
