STS SERIES 1 PHASE
General Features
Uninterruptable transfer between two Independent sources
1phase only or twice way
Totally DSP controlled technology
Synchronous/asynchronous transfers ability
Source priority selection
Temporary protection for input and output sources In an overload situation
Automatic and manual transfer
Ability to change the damaged source On load
By means of DSP control technology, short reply time and diagnostics
Password protected menu structure which whole applications can be made from it
Advanced communication options for remote control and monitor Language selection on the LCD panel
Audible Alarm
High efficiency.
Load overloads and faults
In the event of an overload, the user can decide the level of invervention of the internal protections in order to block the supply of energy. In the extreme case a downstream short circuit, STS disconnects the load, in order to prevent jeoardising the operation of other loads.
Total microprocessor control
Microprocessor control logic ensures:
Fast and safe switching between power sources
Monitoring of all parameters via LCD display
Constant control of SCRs
Advanced remote diagnostics (RS232)
High protection
In the event of an output short circuit, STS will block the transfer between the two power sources limating the risk of propagating the short circuit and ,its effects on the other loads. A blackfeed control circuit ensures the automatic intervention of protection devices when a return of energy to one of the two STS inputs is detected.
Accessibility
The layout of the moving components and parts is designed to ensure easy frontal access:
Power cable connections that are easily accessed with entry from below
Boards housed in a dedicated area for rapid diagnostic/ replacement
All parts subject to controls, maintenance and/or replacement.
STS provides information, measurements statuses and alarms via the LCD display.
