Description
The stabilizers are rated for 220/230/240 V, 50/60 Hz. Efficiency exceeds 98.5 % and waveform distortion stays below 0.1 %, so the load receives no extra harmonics. The unit withstands overload of 10× rated power for 10 ms, 5× for 6 s and 2× for 1 min, which covers motor starting currents. Cooling is natural and fan-free, so there are no moving parts to service. Standard protection is IP21, with IP54 on request. Together with the stated accuracy this makes the unit fit for continuous service rather than short peaks.
How to choose
The model is chosen by load power. Take Ministab M up to 45 kVA and Sterostab M from 15 to 350 kVA, as the ranges overlap. For a three-phase 380/400/415 V network look at Ministab / Sterostab Y with independent regulation on each phase, which tolerates up to 100 % load imbalance, or T with common regulation and up to 50 % imbalance. If only energy saving is needed, there are Ecostab optimizers for 8–2800 kVA and Ecobuck for 5–4000 kVA.

FAQ
What is the power of the Ministab M and Sterostab M single-phase stabilizers?
Ministab M is made for 1–45 kVA and Sterostab M for 15–350 kVA. Together the line covers 1–350 kVA for a 220/230/240 V single-phase network.
What is the voltage stabilization accuracy?
Accuracy is ±1 % RMS and waveform distortion stays below 0.1 %. For most electronics and motors that is enough without extra filters.
What overload can the Ministab M / Sterostab M stabilizer withstand?
10× rated power for 10 ms, 5× for 6 s and 2× for 1 min. That suffices for motor starting currents and short load surges.
Do these stabilizers need fans for cooling?
No, cooling is natural and fan-free. The IP21 version is standard and IP54 is available as an option.
What efficiency do the Ministab M and Sterostab M stabilizers have?
Efficiency exceeds 98.5 %. Losses are small, so the stabilizer can run under continuous load without noticeably heating the room.
