| This UPS system with pure sine wave output. | |
| It can provide reliable and high quality AC power supply to a wide scope of applications from computer equipment, | |
| telecommunication systems to industrial facilities. | |
| It outputs pure sine wave on inverter mode; | |
| when normal AC source is cut, | |
| it will turn into inverter mode automatically and provide back-up power from the battery. | |
| MAIN FEATURES | |
| • Sine wave output applies to different kinds of electronic products as below. | |
| • Microprocessor control technique with high performance. | |
| •Wide adjustable range for input voltage, high degree of accuracy for output, automatic voltage regulation. | |
| •High reliability with protections for overload, short circuit, over voltage, under voltage and overheating. | |
| •Modularized circuit PCB design for easy installation and field-maintenance. | |
| •Instant auto-sensing and auto-adjustable chargers for optimized battery performance and prolonged battery longevity. | |
| •Efficient toroidal transformer at lowest energy loss |
