Its
equipments strictly require an uninterruptible power with
anti-interference in process. STS is an alternative choice to offer a
high reliable redundant power supply for critical loads.
Both UPS#1 and UPS#2 are synchronized and fed by Mains while load is
fed by STS. If one of UPS is totally faulty and no output, the critical
load will be fed by the reserve line. The STS ensure continuous power
supply for critical loads. |

Features & Benefits |
| Features： |
| Fast switch designed, No cut off load when transfer between mains and inverter or UPS. The transfer time can be set from 0ms to 20 ms. |
|
Very fast detection time, if inverter or mains is faulty, to ensure transfer
to reserve power |
| Protection for lacking phase, low and high mains voltage and audible alarm. |
| User can option on line and off line operation. When on line, if the UPS or inverter AC is faulty, the load is transferred to mains supply. |
| When off line, if the mains is faulty, the load is transferred to UPS or inverter supply. |
