Low Frequency Online UPS (Uninterrupted Power Supply) WXX

Applicationsof Low Frequency Online UPS (Uninterrupted Power Supply):
Our low frequency online UPS is ideal for electrical isolation necessary placesor power fluctuation sensitive equipments, including: workstations, computersand peripheral devices, medical equipments, lighting of fire fighting systemand telecommunication equipments etc.;

Features of LowFrequency Online UPS (Uninterrupted Power Supply):
1. UPS power switch has auto detecting functions; one-touch power on functionis available in this uninterrupted power supply and any misoperationwill not cause the failure of our UPS;
2. Intelligent LCD display; v 3. I.G.B.T and P.W.M.20KHz inverter technology isavailable;
4. Independent charging circuit which is suitable for lead-calcium water freebattery and NICR battery etc.;
5. H class insulation for the transformer choke of the main circuit;
6. 10 times of electric power supply abnormality can be memorized for inquiry.
7. Synchronizer: synchronized frequency and same phase with the commercialpower; and if the synchronizer of this electric power supply product is breakdown, the inverter can still work normally.
8. Automatic load balance system is available in our uninterrupted powersupply.
9. Safe battery charging for the adoption of automatic current regulationsystem; and the system also prolonged the battery life and battery dischargetime.
10. Short circuit protection system is available to prevent disasters;
11. RS-232 and RELAY signals are available for linking computer system; andthey are applicable to Windows 95/98/2000/NT/ME/XP, NOVELL / SNMP / ASMP /LINUXsoftware.
