Impedance voltage: ≤7.5% (adjusting in the range of 50% ~100%, impedance is linear )
Short-circuit ability: continuous discharge 8 cycles not causes any damage on the regulator winding, short circuit current reach 2.5IH.
Over-load ability: 60mins at 1.2IH, 30mins at 1.4IH, 5mins at 1.6IH.
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.
