What is the load that can be connected?
General heating element
It shows a heating element with a small resistance to heater temperature, such as nichrome or iron chromium.
Precious metal heating element
Pure metal heating elements such as platinum, molybdenum, kantal super, tungsten, and non-metallic heating elements such as molybdenum silicate shows large resistance change about 10 times to the heater temperature.
For this load, the current limiting function and constant current function are ideal for control.
Silicon carbide heating element
Silicon carbide heating element shows a large resistance change to the heater temperature, and a heating element whose electrical resistance changes over time due to the wear and tear of the heater. The current limiting function and constant power function are ideal for control.
