||||||||||||||||||||||||||||||||||||||||||||||||||| PT8A3252/54 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| |||||||||||||||||||||||||||||||||||||||||||| 5LED Ceramic Heating Controller Features Description  Pulse trigger with high current for SCR  Quickly Heating-Up and Quickly Lost-Heat- Recover  External Adjustable to fit wide range heating plates  External Adjustable to different TCR of sensors  Full temperature compensation and insensitive to environment temperature  5 Heat Temperature Settings  Auto power off (only for PT8A3252)  Over Temperature protection  DIP-16 and SOIC-16 packages Applications  Ceramic Heating Controller  High watt density Alumina Heaters The PT8A3252/54 is specially designed for ceramic heating control with 5 internal level of 130C, 145C, 160C, 175C, 190C.
And the temperature range can be adjusted from 100C to 250C by external series resistance.
It can drive SCR directly and detect heater temperature by heater-self without extra temperature sensor.
It has 3 keys for function setting, 5 LEDs for working status indication.
The PT8A3252 has an internal timer; it timeouts and device will stop heating automatically after 216000 clock period, ie.
1 hour for 60Hz and 1.
2 hour for 50Hz.
The circuit of Over-Heat Protection will be working for safety when heater temperature reached to 250C.
The chip is packaged in lead free DIP-16 and SOIC-16.
