Sirius Advance voltage stabilizers derive from the SIRIUS type, of which they maintain the main technical characteristics.
The standard integration of some functions and accessories usually offered as optional, complete and enrich the equipment.
The additional features are:
The input automatic circuit breaker (QF1) ensures protection against failure and/or short-circuits inside the unit.
The bypass automatic circuit breaker (QF2) protects the line supplying the load against overload and shortcircuits in bypass condition.
The output motorized automatic circuit breaker (QF3), interlocked with the bypass switch, protects against overload, short-circuit, overvoltage, undervoltage, phase sequence error and phase failure.
The integrated automatic Power Factor Correction system maintains the power factor value (cos φ) to a high level ensuring the known advantages for the users but also affecting the sizing of the stabilizer. The PFC system exploits high energy density metallised polypropylene three-phase capacitors (Un=525V) exclusively thus guaranteeing robustness and reliability. The addition of blocking reactors (detuned ﬁlters) eliminates undesired harmonics and protects the capacitors.
The reactive power controller is mounted on the external control synoptic panel.
