Is there a difference between 110V and 220V ptc heating film?
The ptc heating chip is a device with a positive temperature coefficient, and its resistance value will increase significantly with increasing temperature.
If a 220V heating chip is used on 110, the resistance increase is relatively small, and the current will be relatively large, but the heat generation may not necessarily increase much.
Advantages of air conditioning insulated PTC heating source
1. The heater is insulated, the surface is not charged, and human contact will not cause electric shock.
2. After long-term use, the accumulated dust and impurities will not cause a short circuit and will not cause a fire.
3. The heater is insulated and has a waterproof design. It has good waterproof and moisture-proof performance. Water splashed on the surface of the heater will not cause electric shock and short-circuit burnout of the heater.
