Keseco Co., Ltd.  

We are producing Power saving Appliance"ultra".
Ultra is the new concept of energy saving devices, totally different from existing power saving devices. Most of savers reduce the electricity cost by dopping voltage but it  causes another problems. In case of the lighting the voltage drop system lowers the intensity of lighting.For this reason , existing power savers are not welcomed in hotesl or department stores which require the high intensity of lighting.  For the industry use,  short of voltage decrease the torque, which cause critical damage to machinery.

We can see many side effects of using energy savers. Ultra is a incredible solution for this matter. It minimizes load and increases current efficiency without dropping voltage to maximize power saving. We are confident to say "ultra" can satisfiy our customers who need constant voltage as well as energy saving.
