DDJ200-40 直流電磁接觸器DC contactor
用途Application
DDJ200-40型四路常開直流接觸器，主觸頭適用與交流380V、220V、110V和直流6V110V等不同電壓上使用，可用與泵電動機以及其他電動車輛的電源開關操作，同時應用于通信基站電源EPS電源、不間斷電源和其他工業電源上，其特點是啟動和斷開同步，解決了交流接觸器因線路欠壓所引起的接觸器不工作的問題，同時是一種型產品，性能穩定，質量。
DDJ200-40 te the 4 rmally open DC contactors，the main contacts are suitable for AC 380V，220V，110V and DC 6V-110V and so on. It could use for the pump motors and other electronic vehicles，also apply to communication base station power supply，EPS power supply，uninterruptible power supply and other industrial power supply.It solved the unwork problem which cased by the AC contactors lack of voltage，the characteristic is start and off synchronization，is an energy-saving products.Stable performance，reliable quality.
