The SX460 AVR is fitted as the standard AVR for generators in the lower power bands (less than 200 kVA). This is a low cost AVR for low-tech applications where paralleling is not a requirement. The voltage regulation is in the order of ± 1.5%*. The UFRO feature operates at a preset point 95% of the operating frequency.

The SX440 AVR is fitted to a generator in the range of 250 – 800 kVA as standard and as an option on generators of 22 –250 kVA . The voltage regulation is in the order of ± 1%*. The UFRO feature operates at a pre-set point 95% of the operating frequency. A range of accessories is available for this AVR including the requisites for parallel operation.

This AVR is offered as an alternative to the SX440. It has the advantage of better regulation, ± 0.5%*, UFRO at 95%.of the operating frequency and 3 phase 3 wire sensing ideal for supplying unbalanced loads. Newage electrical accessories are available with this AVR.

This is a smaller AVR similar in performance to the SX440. The reduced size makes it ideal for mounting inside the smaller terminal box of the BC range of generators. Regulation of ± 1%* , UFRO circuit preset at 95% of operating speed. This AVR is either powered from the output terminals or from an auxiliary winding as fitted to the BC184. Ideal for marine applications and is an economical way to improve motor starting.
