Inverter By Aims. AIMS Power PWRINV400W 12 Volt Power Inverter with Cables, 400W continuous power, 800W surge peak power, Modified sine wave, Green LED on front panel to confirm power on, Red LED on front panel to warn of a faulty condition Modified Sine Wave Power Inverters represent the most economical solution for powering a large number of appliances. The waveform produced by a Modified Sine Wave Power Inverter is blocky resembling a set of steps whereas the waveform produced by utility companies is smooth much like a curvy road. Key Features 400W continuous power 800W surge peak power Modified sine wave Green LED on front panel to confirm power on Red LED on front panel to warn of a faulty condition Dual ac receptacles On/off switch Over Temperature protection Over Load protection Includes cigarette lighter connection with built in fuse Isolated ground neutral AC output short circuit protection Aluminum case for optimal cooling Specifications DC input/operating voltage: 10 to 16V Output voltage: 120V AC Output frequency: 60 Hz Battery low voltage alarm: 10.5 +/- 0.5V Battery low voltage shutdown: 10.0 +/- 0.5V No load current @ 12V: 1A Full load efficiency: 90% 1/3 load efficiency: 95% No load minimum operating temperature: 32F Full load maximum operating temperature: 104F (automatic shutdown) High input voltage protection: 16 +/- 0.5 Low input voltage shutdown: 10.6V +/- 0.3 Product size (LxWxH): 7.0"x5.0"x2.13" Weight: 2 lbs 400W continuous 800W surge Operating voltage 10V-15V Over Temperature/Over Load/Short Circuit/High Low Voltage Protection Includes cigarette lighter connection with built in fuse (180W max) and direct connect cables Aluminum case for optimal cooling
