Brand WELLSEE Category Automotive Inverter Model WS-IC500B Weight 1.2 kg Size 165*88*48mm ModelWS-IC500B (chargeable) BrandWELLSEE Features: 1. The inverters are manufactured by imported components with an advanced circuit design and 90% conversion efficiency. The strict management system of production and quality with modern assembly lines ensures the product quality. 2. The products have complete specifications, which are aimed at different international standards, there are a total number of models available for selecting. 3. The internal protective circuits prevent electrical pulses or voltage fluctuations effectively, which can withstand the large impact power of the electrical appliances, such as compressors, televisions, monitors etc. with a safe start. The power switch can cut off the internal power supply completely, which protects the storage battery from damages. 4. The self-protection design makes it possible that it will stop working automatically when the voltage is lower than 10V, which guarantees that the storage batteries have enough power to start the automobile. 5. It will stop working automatically when overheating or overloading, and start again automatically when the condition returns to normal. 6. It works without noise, which can be used without maintenance for years by normal operation. 7. It has a diversity of input and output ways: 12V input, 24V input, cigar lighter input; 220VAC output, 110VAC output etc., which can meet the demand of both domestic and international users for mobile alternating current. 8. It adopts an aluminum alloy casing with a beautiful shape and the technique of a high pressure plasma oxidation surface with high hardness and oxidation resistance. 9. Output waveform: pure sinusoidal wave (distortion rate <2%) Characteristics of safety: 1. Overload protection, the power will be automatically cut off. 2. The integral fuse provides the safety guarantee. 3. Low voltage warning, the power will be automatically cut off 4. Overvoltage protection, the power will be automatically cut off. 5. Overhumidity protection, the power will be automatically cut off. 6. Short circuit protection, the power will be automatically cut off. 7. Pure sine wave output, distortion rate, 2% 8. 90% conversion efficiency Technical Index: Max continuous power500W Max Efficiency>95% Input VoltageDC11V-15V Output VoltageAC198V-242V Current while no load0.25A Ambient temperature 0?0 Output Wave shape:Pure sine wave THD2% Warning while low voltage10.4V?1V High voltage to cut off DC15V-16V Low voltage to cut offDC1V-11V Operation: Insert the front part of the product into the cigar lighter socket.
