Voltage stabiliser
Description
Three-phase voltage stabilizers for stationary operation with common or separate control of the three phases (sizes SD 1 to SD 20).
With built-in on-off switch in the input up to size SD 14. The devices are installed on a base frame in IP 00 (version A+D) or switch cabinets or angle iron frames in accordance with protection class IP 20 (version B+C, E+F) and have analog voltmeters and ammeters in the output (version C+F).
Advantages
- High accuracy without regulation variations
- compact construction
- Particularly suitable for computer equipment and test facilities
- Protection class IP 00 – IP 54
