The PT8A3263/4/5/6/7/8 are mixed signal CMOS
LSI chips specially designed for heating controller with
the external NTC (Negative Temperature Component)
sensor. NTC open protection is implemented for device
safety and selectable 5 or 6 heating temperature levels.
PT8A3263/64 are for 5 step levels (eg.100,
120, 140, 160, 180) and PT8A3265/66 are for
6 step levels (eg. 100, 120, 140, 160, 180,
200). They can drive TRIAC or SCR directly and
detect the heater’s temperature with NTC sensor input.
They have up/down keys for temperature setting, On/Off
Key for heating on/off control and 3 LEDs display mode.
PT8A3267/68 have 6 step levels (eg.100, 120,
140, 160, 180, 200). They can drive TRIAC or
SCR directly and detect the heater’s temperature with
NTC sensor input. They have up/down keys for
temperature setting and On/Off Key for heating on/off
control. They also have 1 second (2 seconds for
PT8A3268A) delay function before go into off state and
lock-key function. Their LEDs have special running
flash mode (mode 4)
These devices can be used in both 120V and 240V
power line system, as they can automatically adjust the
heating power according to the power line voltage to
avoid heating appliance damage or long heating time.
They have selectable build-in timer to enable/
disable auto-power off function after turn on 1 hour and
the timer is 1 hour both under 60Hz and 50Hz power
supply.
