TYDZ 20KVA/0.380kV/0~0.42kV Contact type regulator

Mode: TYDZ 20KVA/0.380kV/0~0.42kV
Input voltage: 380V                                 Rated current: 52.6A
Output voltage: 0-420V                            Outer dimension: 800mm*700mm*1500mm
Rated capacity: 20KVA                             Weight: 350kg
Short-circuit ability: continuous discharge 8 cycles not causes any damage on the regulator winding.
Cooling: ONAN                                           Working time: 1hour on
Note: include - magnetism oil surface indicator, servo motor driving device, position indicator with terminal contacts and protection contacts.
The symmetrical compensation and reversed polarity voltage regulation circuit is adopted so that output voltage of the regulator keeps smooth and linearity, and regulating speed can be set and to be very stable. The interlock between voltage regulator, control table and secondary switch are available.
