Heating Controller

Features

Description



Dual Voltage (120V/240V) operations

Auto temperature control with NTC

The PT8A3270/1/2/3/4/5/6/7 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.

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

proportional control algorithm is designed in this

product.
