2.Power-off backup time:15 min full load(1000w);35 min half load(500w)
3. Wave form distortion: empty load<1%; full load <3%
4. Output power :1000w
5.Permitted overload:2000w,30sec
6.Safe standard: GB 7260
Feature:
1. Wide frequency and wide voltage input improve environment adaptability
2.Surge power: above 2000w to short circuit, 3 sec
3.When the environment temperature is higher than 80·c ,UPS will stop output automatically, and it continues to work when the temperature is lower than 45·c
4. UPS will alarm when the load on it is over 1200w.Alarm will last about 30 sec
5. Automatic short circuit protection for surging. when the surging less than 2sec
6. When the accumulator cell is put away separately.PLS leave a ventilation hole on the storage box to extend its service life and reliability of the whole system.
