With improved heat sink design and a specially designed 2-stage TEC, QHY9 can reach maxium -50degree temperature difference from ambinet. The TEC power consumpt reduced to only 20Watt(less than 12V2A,at the maxium PWM) There is a build in temperture sensor and a 16bit ADC for this sensor. With new DC103 powersupply the tempeture is fully loop controlled.
QHY9 is fully airproof. With two air socket (4.0mm standard).
