Feature: <br> <br>The wire used in the heater are all high temperature resistant silica gel wire, and the temperature resistance is more than 200 C. <br>This product is suitable for small space heating, dehumidification and warmth preservation within 0.5 cubic meters. <br>The service life of the product is long. The general standard is that the power attenuation after 3 years is less than 10%. <br>Because of the temperature resistance limitation of the fan, the heater is suitable for the ambient temperature range of -5 - 65℃. <br>Surface insulation, safe to use. <br>This product is suitable for heaters, air conditioners, automobiles, etc. <br> <br>Specification: <br>Voltage: 110V <br>Rated power: 250W; 350W(Optional) <br> <br>Working voltage of fan: 12V; 24V (Optional) <br>Product dimension: Approx. 90 x 61 x 42mm / 3.5 x 2.4 x 1.7in <br> <br>Distance of installation hole: Approx. 86mm / 3.4in <br>Diameter of installation hole: Approx. 4mm / 0.16in <br>Suitable room: <0.5m3 <br> <br>Package list: <br>1 x PTC Heater with Fan <br> <br>Note: <br> <br>Red is the positive pole and black is the negative pole. <br>The outlet wires of heaters and fans can be separately connected to the power supply. Fans must be inputted by DC. PTC heaters are not divided into AC and DC. <br>The power of all PTC products is not a fixed value, but a range. The power range of this fan heater is within the (+20%) range of the labeled power. The power of different ways of using the same product is different. Simply speaking, the better the heat dissipation, the greater the power. <br>The actual product color may deviate from the photo due to light. <br>There may be a slight deviation in the measurement of product. <br>Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.<br>1、The wire used in the heater are all high temperature resistant silica gel wire, and the temperature resistance is more than 200 C. <br>2、This product is suitable for small space heating, dehumidification and warmth preservation within 0.5 cubic meters. <br>3、The service life of the product is long.
