Working time: working 60 min under 100%UH,100%IH; continuous working under 2/3UH,2/3IH; reactor winding temperature raise ≤65K, oil surface temperature rasie ≤55K, external surface temperature rasie ≤30K.
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.
