Resistive Load Banks
R Series
Load banks are devices which contain resistive, inductive and/or capacitive loads, apply the load to an electrical power source and dissipate the power of the electrical source. Portable and stationary resistive load banks incorporate as low as 1 kW load step increments for testing small to large generating sets. The fine control resolution ensures accurate load control and power factor targeting adjustments.

Resistance Welding
Resistance welding is a method in which the welding works are heated by resistance heat generated by sandwiching the welding workpieces with welding electrodes, passing current through them, and the metal is welded while pressurizing the works.A resistance welding machine composed of welding power supply, a weld head and an electrode. The welding power supply controls a welding current,the weld head exerts a pressure on the material to weld and the electrode provides welding current and pressurization force to the part under welding. We have been providing various kinds of welding power supplies and welding heads to meet these requirements.
