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.
