1. The heater element itself regulate designated
temperature range.
(Temperature can change depending on how to use it)
2. The temperature pulsation which is observed in case
on-off temperature control system can be
eliminated.
3. Output wattage is decreased automatically when
heat radiation is decreased.
(Overheating is very small compared to constant
wattage heaters)
4. Compact and flat surface makes it easy to
install in applications.
5. Depending on application, these PTCs realize dual
voltage use.
(Output wattage does not change much between 100V
through 260V)
