Product Main


Combined SPDs are multiple function SPDs which can provide power supply protection, signal protection and/or antenna feeding protection. Generally, a combined SPD consists of two parts: Power supply protection and signal protection. Combined SPDs are usually used in cell station, network equipment, etc.
