Description
Intended for assembling electric metering and distribution empty enclosures using modular equipment, electric power supply and distribution as well as protecting networks of 230/400 V from short circuit and overcurrents. Correspond to EN 62208.
Advantages
- The most up-to-date principle of switching based on use of powerful contactless electronic switches, triacs.
- No mechanical contact between switching parts and no wear of the stabilizer, thus ensuring high operational reliability and long lifetime.
- Perfectly noiseless work (can be used in living premises).
- Extra quick response to changes of input voltage: response speed 20 ms.
- Improved accuracy of stabilizing: 4% over range 140-250 V.
- High efficiency: more than 95%.
- Extended output voltage range: 90-270 V.
- No distortions of the output signal sinusoidal shape (switching between the autotransformer winding leads takes place at transition through "zero").
- Six protection levels: against overload, short-circuit, overheating, hazardous overvoltage, hazardous undervoltage, surge voltages.
- No distortions of sinusoidal shape.
- Broad national network of service centers for IEK voltage stabilizers.
