It is the device to supply DC and AC powers with a set of battery to distribution facilities (HV SWGR, ACB, Inverter and emergency lighting) for plant electric and instrument facilities and other important facilities.  Its UPS (Uninterruptible Power System) and battery charger supplies fully automatic constant voltage.  Particularly it supplies accurate and stable operation power where input power or loads vary severely.   

 

• Charger and inverter capacities are subject to mutual discussion.

 

• Key Features of Static Transfer Switch

- Automatic switching without momentary outage to the standby line upon primary power source outage
- Automatic switching without momentary outage to the standby line upon low voltage in the primary power source
- Manual switching without power interruption to the standby line for line maintenance and load balancing
- Various indications such as output voltage and output current
- Large capacity up to 30 A
- Detecting power outage, low voltage and high voltage
- Constant output monitoring
- Random time recovery
- Self-diagnosis and alarms
