Wide range of temperature characteristic shall make easier to select most suited heater device matching to the application. ø4 .3 23 29.5±0.5 37±0.7 19 B 6 11 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) 3 6.5 3 PTWSB Series in mm ø7 .5 21±0.5 13 30±0.5 40±0.5 30±0.5 3 5.3 5.4 1.5 ø5max. ø5max. 1.0max.
