Feature: 1. 1500W PURE SINE WAVE UPS INVERTERS: The 12v power inverters provide 1500 watts of continuous power and 3000 watts of peak power, converting direct current to alternating current, and can be used for automotive, home, camping, RV, solar panel power, and emergency 2. INDUSTRIAL COPPER TRANSFORMER: 99.6% effective voltage inverter from DC to AC, bring higher power conversion, more durable and stable than ordinary transformer, more robust output. Using industrial electronic components, the product application efficiency is higher, the performance is more stable 3. VARIOUS SAFE PROTECTION: Inverter adopt advanced isolation input and output technology design, safety is improved, with overload, low voltage, high voltage, overheating, short circuit protection function, more assured to use 4. GOOD COOLING: The off grid inverter has an adequate cooling fan with a cooling aluminum alloy housing with multiple vents designed to prevent overheating. With infinitely variable speed and temperature control settings, the heat generated by the machine depends on the fan speed, which is really quiet and comfortable to work in a quiet environment 5. POWER INVERTERS FOR VARIOUS APPLIANCES: Directly connected to 12 volt DC (car battery) inverter into AC power outlet, can be used to power laptops, tablets, printers, DVDS and other small devices or any other household appliances, smart USB port 5V 2.1A for charging USB powered devices. Whether inductive load or resistive load electrical appliances can be used, widely used in household appliances, vehicles, field work, industrial, office, tourism, etc. Specification: Item Type: Pure Sine Wave Power Inverter Material: Aluminum alloy and copper Output Power: 1500W Peak Power: 3000W Display: LCD Output Waveform: Pure sine wave Input Voltage(DC): 12V USB: DC5V 2.1A Output Frequency: 50Hz or 60Hz Working Temperature Range(rated): 32?H-104?H, 0??-40??
