-
Designed for use in high voltage, medium voltage and low voltage switchgear
-
They are designed for switchgear with a typical configuration comprising two power supplies (feeder lines or power transformers) and two busbar sections connected by a busbar tie
-
Depending on the device model, the number of signal inputs and control outputs can be flexibly expanded
Find out what the BELplus SZR controller has to offer
The BELplus SZR controller is designed for use in switchgear for high voltage, medium voltage and low voltage. By monitoring the voltage on the busbars and, optionally, the reserve voltage on the supply lines (or on the primary side of the transformers), the device typically supports switchgear with a standard configuration of two power supplies (supply lines or transformers) and two busbar sections connected by a busbar coupler.
The controller implements automation for transfer switch (ATS) operation in either explicit or implicit standby mode. The device can automatically adjust the standby mode to the position of the main circuit breakers, or it can only commence operation once the position of the circuit breakers matches the selected operating mode.
