Product Description About Us

DC SPD (Direct Current Surge Protective Device) is a surge suppression device specifically designed for DC systems to limit transient overvoltages and discharge surge currents. It contains at least one nonlinear element capable of responding within nanoseconds, diverting surge energy to ground and clamping the voltage to a safe level to protect downstream electronic equipment.
