The PT8A336x is a mixed signal CMOS LSI chip
designed as heating controller with help of external NTC
(Negative Temperature Component). NTC open
protection is implemented for device safety and 11
temperature levels. It can drive TRIAC or SCR directly.
It has 3 keys function setting. LCD displays and
backlight indicate the working status.
This device can be used in both 120V and 240V power
line supplier, as it will automatically adjust the heating
power according to the power line voltage to avoid
heating appliance damage or long heating time.
The PT8A336x build-in timer will be auto-power off
after power on 1 hour both 60Hz and 50Hz.
