| Voltage Control Unit | 
 | Item Code:AVR-AX-01 We have in store for our clients, a technologically advanced gamut of voltage control unit - Ax-01 whose voltage regulation is derived from the line U.V. and neutral of the A.C. Generator. Forming a closed loop system, the generator phase of the AVR is rectified, attenuated, filtered and regulated to a suitable value. This range is provided to our clients in the following specifications:
- Designed using latest technology, the Voltage Control Unit (AVR) is in a solid and encapsulated state
- AVR supplies power to the exciter field of A.C. generator with a frequency change of not more than +/- 4%
- The generator voltage recovers to nominal value within 0.5 sec upon application or rejection of rated load
- The design aspects of the exciter & A.C. Generator is dependable for the transient performance
- For more than 10% harmonic distortion, voltage regulation may be outside the limit specified for the R.M.S. average or the peak voltage.
- The regulation figures out side the limit are produced from unbalanced load on 3 phase A.C. Generators
- Special filters are incorporated in AVR for giving optimum performance on non linear loads
- AVR is tested and set to standard voltage, frequency and stability for delivery
We also manufacture Open type AVR's Model AX-01(MK1)
