Overview

Product Description

The PT8A3362H 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 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 PT8A3362H build-in timer will be auto-power off after power on 1 hour both 60Hz and 50Hz.
