Description
The Taurus works from an input voltage of 140–250 V and needs 1–3 ms for each volt of correction. Taurus efficiency is 98 %, so little energy is lost in the stabilizer itself. The operating frequency is 49–62 Hz. All models have an input breaker and some also have a manual bypass, which takes the stabilizer out of service without de-energizing the consumers. The series covers everything from a single consumer at 1 kVA up to a three-phase feeder at 100 kVA.
How to choose
Choose the model by the number of phases and the power. For a single-phase load up to 15 kVA take the Taurus or Lyra, for a three-phase one the Taurus Y at 5–100 kVA, while the Polaris covers 10–100 kVA. Accuracy of ±2…3 % suits equipment that does not demand tight tolerances. If ±0,5 % accuracy is required, look at the static three-phase Aquarius, 10–120 kVA, which tolerates load unbalance of up to 100 %.

FAQ
What power do the Lyra, Polaris and Taurus stabilizers have?
The Taurus and Lyra offer 1–15 kVA on one phase, the Polaris 10–100 kVA, and the Taurus Y 5–100 kVA on three phases.
What is the input voltage range of the Taurus?
The input voltage is 140–250 V and the regulation speed is 1–3 ms/V.
What is the stabilization accuracy?
Accuracy is ±2…3 %. Tighter tolerances call for static models with ±0,5 % accuracy.
What are the efficiency and mains frequency of the Taurus?
The Taurus efficiency is 98 % and the operating frequency is 49–62 Hz.
Do the stabilizers include an input breaker and a bypass?
An input breaker is fitted in all models and a manual bypass in some of them.
