Your genset and ATS are working well. I have given your name and email to a friend who will be building a hotel in Palawan. Thanks,

—— K.S. LIM

Thanks always giving me good products. thanks for your effort you done before. your firend from Egypt.

—— Waleed-Egypt

I must confess you have a brilliant customer relations skills and i am learning from you. I tell you if you want to see how beautiful Zambia in Africa

—— Akakulubelwa Mwiyakui-Zambia

hi jenny, the powerwizard 1.1 i brought work perfect

—— Dr Claude VILLETTE -----France

I purchased a Jackpower generator from your company in January or February 2008 (ten years ago). The generator has served me very well for 10 years,but the fuel filter has become blocked.My problem is that now that the new filter is fitted, I cannot find anywhere to bleed the air out of the fuel system. I would be very grateful for any help from u

SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator

The Propose employs surface mount technology (SMT) for high integration of features in a minute footprint AVR. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. The control and voltage sensing circuits have separate terminals, allowing the excitation power to be resulting directly from the stator winding for necessary applications or from an auxiliary winding if sustained short circuit performance is essential. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/- 1%
