[Name]High-power power supply soft-start circuit board This product is not suitable for motor use[Relay] RGL high-power super-current 100A pure copper foot relay[Size] 67mm x 61mm x 30mm (height), ultra-small size[Scope of application] Suitable for high-end audio power input, or other large starting current machine applications. The power used is suitable within 2200W. The long-term load is preferably within 1200W!Power supply voltage adaptable range: AC 150V to 280V.main feature:The function of the soft start board is to reduce the inrush current at the moment of startup, so as to reduce the impact of the machine on the power grid and prolong the life of the switch. This board uses ultra-high current (100A) pure copper foot relay and ultra-large thermistor NTC 20D-20, which can effectively protect the machine and prevent excessive power-on current.This board does not need auxiliary power supply, only 2 terminals, one is connected to the power input (previously connected to a switch control), and the other is connected to the load, which is very convenient to use.color:BlackMaterial:PCBPackage Contents:1 x Power soft start boardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
