Feature: 1. COPPER INVERTER: Adopts copper material, the inverter power is higher, more durable, stable and more powerful than ordinary inverters. Adopting industrial electronic components, the product has higher application efficiency and more stable performance. 2. EXCELLENT HEAT DISSIPATION: The inverter has a cooling fan and a multi vent design of aluminum alloy shell for heat dissipation to prevent equipment overheating. 3. LOW NOISE OPERATION: The inverter adopts stepless speed change and temperature control settings. The fan speed is determined by the heat generated by the machine. Truly silent and comfortable work. 4. SAFE USE: Advanced isolation input and output technology is adopted by the inverter, improved safety, with overload, low voltage, high voltage, overheating, short circuit protection functions, more secure use. 5. WIDE APPLICATION: The inverter can be used for supply power to small devices such as laptops, tablets, printers, DVDs or any other household appliances. Both inductive load and resistive load electrical appliances can be used, widely used in household appliances, vehicles, field operations, industrial, office, tourism, etc. Specification: Item Type: 3000W Pure Sine Wave Inverter Material: Aluminum Alloy, Copper Output Power: 3000W Peak Power: 6000W Display: LCD Output Waveform: Pure sine wave Input Voltage (DC): 24V USB: DC5V 2.1A Output Frequency: 50Hz or 60Hz Working Temperature Range (rated): 32 ℉ to 104 ℉, 0 ℃ to 40 ℃ Low Battery Alarm Range (rated): 20-121V Low Power Off Range: 19.4-120V High Power Off Range: 30V.
