PTC Air Heating for Electric Bus, Self-Regulating Heater, Low Temperature Performance

Product overview

PTC heater is most widely applied to electric bus today for air heating. Compared to traditional heater, it is safer and more dependable because the self-regulating PTC element will not be damaged without air flow. Also, power of thermostat will automatically be cut off when it is overheating.

It is an excellent air preheater for vehicles to start under -40ºC since it can start quickly under low temperature condition.

Remark

• Voltage can be selected from 250~600VDC, up to 900VDC
  
• Waterproof grade is IP67

Product Features

• Self-regulation PTC element, heater will not be damaged without air flow
  
• Multiple insulation. Electric strength can reach 2500VAC. Leak current is less than 5mA
  
• Excellent low temperature start performance, it can be quickly turned on heating even under -40ºC
