Generator Spare Parts

The full name of ATS is Automatic transfer switching equipment, in the supporting use of the generator set industry. ATS is mainly used in emergency power supply systems to automatically switch the load circuit from one power supply to another power supply to ensure continuous and reliable operation of important loads. SKT series automatic transfer switch is the most advanced third generation ATS. It's of PC Class (one-piece structure). SKT standard type is able to operate the current from 20A to 3200A.

The AS440 is an analogue, 2-phase sensing, self-excited automatic voltage regulator (AVR). The AS440 incorporates Surface Mount Technology (SMT) to its design.
The AS440 is supplied as standard to the STAMFORD® S4 and STAMFORD® HC5 alternators and is an option for the STAMFORD® UC22 and UC27 alternators.

Attention please!
The AVR SX460 is now obsolete and replaced by the AVR AS440. The production of original Stamford AVR SX460 is definitely discontinued.
The SX460 is an analogue, 2-phase sensing, self-excited automatic voltage regulator (AVR). The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage.
The SX460 is most commonly used on Stamford alternator UC range and are supplied as standard to the UC22 and UC27 alternators.

The MX321 analogue, 3-phase sensing, permanent magnet generator (PMG) powered automatic voltage regulator (AVR) provides isolation from the effects of non-linear loads, improved motor starting performance and sustained short circuit current.
The MX321 AVR is provided as standard for the STAMFORD S6 and HC6 alternators and can also be provided as an option across the STAMFORD range.

The MX341 is an analogue, 2-phase sensing, permanent magnet generator (PMG) powered automatic voltage regulator (AVR) providing isolation from the effects of non-linear loads. It has improved motor starting performance and sustained short circuit current.
The MX341 is provided as standard for the STAMFORD P6, STAMFORD P7 and STAMFORD S7 alternators.

The AS480 is an analogue, 2-phase sensing, self-excited automatic voltage regulator (AVR) incorporating an interface for the optional Excitation Boost System (EBS) for improved motor starting performance and sustained short circuit.
The AS480 is provided as standard on STAMFORD P0 and P1 alternators.
