The cooling performance depends on the environmental conditions and
also on the power supply. If the power supply voltage drops below 12 V,
the maximum temperature drop is lower.
CMOS sensor cooling
Thermoelectric (Peltier modules)
Maximal cooling ΔT
~45 °C below ambient
Regulated cooling ΔT
40 °C below ambient (~90% cooling)
Regulation precision
±0.1 °C
Hot side cooling
Forced air cooling (fan)
Maximum temperature difference between sensor and ambient air
may be reached when the cooling runs at 100% power. However,
temperature cannot be regulated in such case, camera has no room
for lowering the sensor temperature when the ambient temperature
rises. Typical temperature drop can be achieved with cooling running
at approx. 90% power, which provides enough room for regulation.
