SIRIUS stabilizers SIRIUS stabilizers are based on column regulators, own development of the company ORTEA. This contributes to achieving high powers – from 200 electric power 6000 kVA and build a solid and reliable structure, to make the stabilizer suitable for any industrial applications. SIRIUS stabilizers stabilize the output voltage to the load within ±0.5% of the nominal, at mains fluctuations of the input voltage from –45% to +30%.

They regulate the voltage independently for each phase and are generally used for stabilized power supply of three-phase and single-phase loads with 100% imbalance between the loads of the individual phases. Due to the independent regulation of the input voltage of each phase, they are also suitable for operation in unbalanced networks. In this case, the presence of a neutral conductor or an isolating transformer with a connection scheme Δ/zn0 or Δ/Y is required .

Two digital multifunctional network analyzers, mounted on the front door display information about input voltages and load parameters, connected to the stabilizer as: phase and line voltages, the flow, power factor, active, full and reactive power.

The operating status of the stabilizer can be easily monitored using an LED interface placed on the front door, which shows all information about the three phases and possible alarms, accompanied by an audible signal.

For powers up to 260kVA ± 15%, fast-acting circuit breakers protect the regulating system against overload and short circuit.
