ARG Series Wirewound power resistors in Al case The Ohmite ARG series features wired connection points with insulated connectors. The finned extrusion profile allows for more thermal efficiencies and can also be heatsinked for more power dissipation. The ARG series resistors are suitable for power elctronic circuits (eg. motor control, braking, frequency converters).
