PT8A330x
Features
High watt density Alumina Heaters
High current pulse trigger for SCR
Quickly Heating-Up and Quickly Lost-Heat-
Recover
Dual voltage 120VAC / 240VAC
Internal 5v zener
Insensitive to environment temperature

Description
The PT8A330X is specially designed for ceramic
heating control system. It can set the temperature
continuously .It can drive SCR directly and detect the
heater temperature without extra temperature sensor. It
has one key, two keys and no key for function setting
and has one LED for working state indication. Build-in
timer will automatically power off after turn on for 1
hour @ 60Hz or 1.2 hour @ 50Hz (for PT8A3300/1/4/5).
