GENERAL CHARACTERISTICS.
The system called STS (Static Transfer Switch) has two independent input sources,
Source A (LINE 1) and Source B (LINE 2). Outputs are connected to the loads which, in
normal operation, are powered by the supply source A
If the source A voltage is missing or is out of range, the system automatically switches the
loads to source B. The STS returns to supply the loads through Source A as soon as this
return is available.
SPECIAL FEATURES
1. Our high frequency power drive technology allows for greater integration of the
SPS, enabling it to be used even in enclosed environments.
2. The totally digital control system (DSP) of the SPS allows you to enhance the
functionality and high level of protection of the machine itself. The powerful
communication port enhances the remote control and supervision of the SPS.
3. The large input voltage tolerance (110-300 Vac) allows the use of the SPS in
critical power situations.
4. The integration of the STS with the ITS allows, in case of anomalies, a rapid
replacement of the device without interruption.
5. The STS is designed to comply with the various international standards on
electromagnetic interference compatibility (EMC).
