'AS3' Series Current Operated Switches from NK Technologies provide the same dependable indication of status offered by the AS1, but with the added benefit of increased setpoint accuracy. A choice of three, jumper-selectable input ranges allows the AS3 to be tailored to an application, providing more precise control through improved setpoint resolution. Self-powering, isolated solid-state outputs, 1-6A, 6-40A and 40-200A input ranges and a choice of split- or solid-core enclosures are standard.
