New 4000w 12v 220v/110v Led Ac Car Inverter Converter Charger Adapter Inverter Dual Usb Transformer Modified Sine Wave SZRH-1

Features:1. Dual LCD digital display allows you to maintain the output voltage and battery voltage value at any time.2. Fault prompt function. In addition to different sound prompts, it can also be displayed more intuitively from the display screen (e.g. battery undervoltage, battery overvoltage, overload, high operating temperature, short- output circuit, etc.).3. The overload delay closing function is added in the product to solve the sensitive problem of protecting the inverter when the soluble electrical appliance is started.4. The small power non-professional user market has increased the positive and negative pole return protection function.5. Intelligent temperature control oil seal fan. When the inverter is working, it can operate at a certain temperature, which is more energy efficient and quieter.6. Digital MCU control, output wave type, more accurate frequency, accurate output voltage, fast response of protection circuit. in cars, steamships, mobile posts and telecommunications, public safety, emergencies and other fields. -15.5VOutput voltage: 110V/220V (optional) Output voltage range: 110V 10% / 220V 10% Frequency: 50Hz / 60Hz of 9.5VHigh voltage protection: with maximum protection voltage of 15.5VOverload protection: YesOutput short circuit protection: YesReverse connection protection of positive and negative poles: YesOutput voltage stabilization: YesBuzzer protection: YesUSB interface: 2.1A x 2Input terminal connection mode: terminalOutput interface: international general socketProduct size (mm):161mm/6.28in x 112mm/4.37in x 56mm/2.18inPackage information:Package Size:187x100x145mm/7.29 x3.9x5.66inPackage weight:650g / 1.43lbGeneral box packagePackage included:1 x power inverter1 x alligator clip1 x cigarette lighterNote:1.Please allow 1-2mm errors due to manual measurement.2.Item color displayed in photos may be showing slightly different on your computer monitor because monitors are not calibrated the same.
