Accuracy: Ministab and Sterostab ensure the true RMS value of the voltage with an accuracy range that varies according to the model from 0.5% to 1.5%, even where strong harmonic distortions are present on the line.

Fast response: The advanced electronic control circuit ensures a fast response, from 11 to 50 ms/Volt according to the model. A controlled deceleration minimizes overshoots.

Overload capacity: A typical characteristic of the Ministab and Sterostab is its regulation system. In fact, they can support without damage overloads up to 10 times the rated current for 10 milliseconds, 5 times for 6 seconds and 2 times for 1 minute.

Efficiency: At full load the range is from 96% for small models to98% for the larger units.

Unaffected by power factor and load variations: The Ministab and Sterostab operating principleensures that the equipment accuracy and regulation speed characteristics remain unaltered under any load conditions, with inductive or capacitive loads.

Unaffected by frequency variations: The servomotor control circuit operates correctly withmains frequency variations up to 5%.

Negligible waveform distortion: The high quality materials and their correct use ensure that harmonic distortion is always less than 0.2% under any working conditions.

Low intemal impedance: Installation of Ministab and Sterostab in already existing systems does not require new calculations for protections since their internal impedance varying from 0.52 to 0.015 ohm does not significantly affect the line impedance.

Operating temperature: Ministab and Sterostab have been designed to operatecorrectly with a maximum environment temperature of 40C under the worst conditions. They ensure continuous operation, full load and minimum input voltage value.

Reliability: The continual improvements that the Ministab andSterostab have undergone over the last 50 years of activity during which IREM has manufactured over 230,000 stabilizers have obtained an exceptional MTBF for these devices.

Conformity to standards: Ministab and Sterostab conform to the requirements of the following standards: Electro Magnetic Compatibility 89/336/EEC and following amendments; Low Voltage Electrical Equipment 73/23/EEC and following amendments.
