MEAN WELL NTS-1700 and NTU-1700 1700W DC-AC Power Inverters are true sine wave DC-AC power inverters with 3400W peak power and adjustable AC output voltage and frequency. The NTU-1700 includes a built-in uninterruptible power supply (UPS) function (AC bypass). Both the MEAN WELL NTS-1700 and NTU-1700 feature a digital design with microcontroller (MCU) control and streamlined control circuitry that quickly responds to environmental changes and improves reliability. These DC-AC power inverters also provide a high-quality fan with low acoustic noise and operate over a -25°C to +70°C temperature range. Applications include home and office appliances, power tools, portable equipment, and more.
