Voltage Stabilizer
Description
Three-phase voltage stabilizers for stationary operation with common or separate control of the three phases (size SD 1 to SD 20).
With built-in switch in the input up to size SD 14. The devices are installed on a base frame in IP 00 (version A+D) or control cabinets or angle iron frames according to protection class IP 20 (version B+C, E+F) and have analog voltmeters and ammeters in the output (version C+F).
Advantages
- high control accuracy without control oscillations
- compact design
- particularly suitable for IT systems and test fields
- Protection classes IP 00 – IP 54
