iNova 2-stage Peltier Cooling Upgrade to CS-L cooling system



This CS-L Cooling system is a Thermoelectric upgrade for iNova PLxCam Series Cameras. It features a single  stage Peltier thermoelectric module and control electronics.

The temperature of the camera sensor is lowered by 20°C (36°F) when operating under ambient temperature conditions. It dramatically reduces Thermal Noise allowing for the long duration exposures required during imaging  of deep sky objects.

TheVisual Enhancement Mode maximizes the efficiency of this cooling system which in turn increases the signal/noise ratio of the camera resulting in sharper images.

  • CS-L cooling system is assembled entirely in-house
  • Peltier module TEC (maximum power: 5.7W),
  • Aluminium case that also serves as heat sink for TEC
  • Electronic card with a microcontroller to manage the Peltier module
  • Fan to improve heat dissipation.
  • Requires an external power supply 12V DC – 2A (minimum)
