Mean Well TS-400 Series 400W True Sine Wave DC-AC Power Inverter TS-400 series 400W true sine wave DC-AC power inverters with digital microprocessor control and high frequency circuit topology enabling a high efficiency of up to 88.5%. These TS-400 series true sine wave DC-AC power inverters are capable of providing 400W continuously for all kinds of harsh load with a low THD of less than 3% peak load capability including 460W for 180 seconds, 600W for 10 seconds or 800W surge power for 30 utility cycles. The output AC voltage and frequency for these DC-AC inverters can be adjusted easily through the front panel. Typical applications for these TS-400 series true sine wave DC-AC power inverters include power tools, office and portable equipment in vehicles, yachts, mobile homes and in other applications where the mains voltage is poor or out of range.
