POSISTORr for Heater
POSISOTRr for Constant Temperature Heating
R19E3.pdf 01.10.26
1
These "POSISTOR" are designed for various applications
for constant temperature heating purpose.
Wide range of temperature characteristic shall make
easier to select most suited heater device matching to
the application.
s Features
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. Out put wattage is decreased automatically when
heat radiation is decreased.
(Over heating is very small compared to constant
wattage heater)
4. Compact and flat surface shall realize easy to
install for various set.
(PTWTA series has electrically insulated heating
surface)
5. Depending on application, these PTC realize dual
voltage use.
(Out put wattage do not change much between 100V
through 260V)
