The peak power of 1000W, for household appliances, such as: LED TV, LED Lights, Light bulbs, Electric Fan, Blender , computer and other. Output Waveform: Pure sine wave inverter Input voltage : DC 12V Output voltage: AC 220V Frequency: 50Hz Max Output power:1000W Continuous power:500W Inverter efficiency:95% Volume: 18.5 * 9.5 * 5.5 (cm) Net weight: 0.8KG''' 6 protections : 1.Input low voltage protection: When the input voltage is less than 10V 0.5V (for 12V input inverter) /20V 0.5V (for 24V input inverter), the AC output will automatically turn off, the buzzer sounds 3 simultaneous fault indicator will be Bright (red). 2.Input overvoltage protection:When the input voltage is higher than 15V 0.5V (for 12V input inverter) / 30V 0.5V (for 24V input inverter), the AC output will automatically turn off, the buzzer sounded 4 simultaneous fault indicator will be Bright (red). 3.Short circuit protection:When the short circuit occurs, the output is turned off, the fault indicator will be lit (red) 4.The battery is extremely anti-protected:When the positive and negative batteries are reversed, the fuse will fuse to protect the load. 5.Inverter temperature protection:When the inverter temperature exceeds 68 '\, the AC output will automatically turn off, the buzzer sounded 5 sound at the same time fault indicator will be lit (red), until the temperature back to 50 '\ after the inverter automatically return to normal. 6.Overload protection:When the load exceeds 110% of the inverter capacity, the AC output will be automatically turned off. The buzzer beep indicator will be lit (red) until the switch is turned off and the inverter is switched on and off. After troubleshooting work status automatically restored. NOTED : Inverter ini walaupun sudah PSW...tetapi tidak kuat buat Kulkas apalagi AC..
