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

Heating Controller

Dual Voltage 120V/240V operations Auto temperature control with NTC open protection Multi mode LED indicator Proportional control Pulse trigger for high current SCR Internal Zener Auto Heating off after heating timer timeout Low cost 8-Pin DIP and SOIC package

Curler Straightener

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.
