TYDZ-30kVA/0.4kV/0~0.42kV Contact Type Voltage Regulator

Mode: TYDZ-30kVA/0.4kV/0~0.42kV
Single phase           Frequency: 50Hz         Rated Capacity: 30kVA
Voltage adjusting methods: electrical drive (single phase DC motor adjusting)
Rated Input Voltage: 0.4kV                          Rated Output Current: 0~71.4A
Rated Input Current: 75A                             Aberration Ration of Waveform: ≤3%
Rated Output Voltage:0~0.42kV               Starting Voltage ≤1.5%

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.
