2000W Cl A Amplifier Power Delay Soft Start Board Power Supply Protection Board AC220V Input

Product descrtion:

2000W high power soft start board uses FR4 fiber , size: 74 X 57 X 26MM The circuit is an and new design. The relay short-circuits the power after the power-on delay. The power uses 4 NTC 10D-20 thermistors with negative temperature coefficients to ensure that the load voltage rises smoothly to the mains and protects the rectifier bridge and water Pond capacitance, extend the service life of electrical appliances. There is no problem with the measured 2000W load. With 30A 6600W sealed relay Power supply: AC 220V Input output (not more than 275V can be use) Circuit working princle: Turn on the power supply ----- power on delay, NTC is connected in series in the output load circuit to reduce and control the starting current (delay circuit control) ----- short circuit NTC after the start is completed, the power supply is directly output. Complete the soft start proce. (24V relay controls 220V voltage output) Ingenious circuit design, no need to connect a small transformer separately, soft start mainly protects the rectifier bridge, and the large pond , to avoid starting the bridge and breakdown , extend its service life. The total current is controlled at 5A, to avoid impacting the power grid during startup, and to prevent the total power supply from trping.
