The ARM-C series is the family of pure sine wave inverter with built-in AC charger. This series features at the moment two output models, 500W and 800W max, both in 12vdc only. Operating primarily like a UPS when AC input is available, these inverters provide bypass power from AC source straight to load, at the same time keeping battery charged with its inbuilt 3-stage charger with up to max 20A (adjustable current). Furthermore, they feature selectable AC input range in either 90-280vac or 170-280vac.
When AC input is not present or insufficient, they will operate like a regular inverter, supplying power to load from battery. Lightweight and compact, these are perfect for small office or mobile applications.
