Function: 1. This product is an electric heater with automatic constant temperature and energy saving. 2. Safety, energy saving, environmental protection, long service life. 3. Solid and gas heating, power attenuation 4. It is suitable for heating, dehumidifying and keeping warm in a small space within 0,5m³. 5. Main applications: heater/humidifier/air conditioner/metro and other popular electrical appliances. Specification: Characteristics: This product is an electric heater with automatic constant temperature and energy saving. Safety, energy saving, environmental protection, long service life. Solid and gas heating, power suppression Operating voltage and fan power rating: #01 12V, 300W; #02 24V, 400W (optional) Appearance Size: 90*61*40mm/3.5*2.4*1.6 inch (including mounting hole) Mounting hole spacing: 86mm/3.4 inch (4mm mounting hole diameter) Note 1. Power is related to the method of use. The power of all PTC products is not a constant value, but falls within a certain range. The power range of this fan is in the range of 20% of the rated power. The power of the same product is different for different uses. In short, the better the heat dissipation, the more power 2. Heater and fan cables can be connected to the power supply separately, the fan must be powered by direct current, and the PTC heater does not ma alternating current ani direct current. 3. The wires used by the heater are all high temperature resistant silicone wires, with temperature resistance > 200 ; red positive and black negative 4. Due to the limitation of fan temperature, the heater is adapted to ambient temperature from -5 to 65 List of packages: 1 x Air Heater
