2000W High Power Soft Start Board 30A Dual Temperature Control Switch Delayed Start Board for Amplifier Amp DIY

Type option 1 Terminal type Songchuan relay 2 Plug in terminal type Songchuan relay 3 Plug in terminal Songle relay 4 Terminal Type Songle Relay 5 Terminal type HF 105F 1 Relay 6 Plug in terminal type HF 105F 1 RelayProduct description Dual temperature control soft start uses high quality power module to replace traditional transformer with low energy consumption high efficiency ultra stable low heat 105 235V wide voltage for domestic and foreign and so on This product PCB adopts 1 6MM thick double sided fiberglass board 2 0 oz copper thickness tin spraying process to ensure good passing of high current It is suitable for high power amplifier and post stage power supply as delay soft start board to avoid high current impact at the moment of booting and better protect your machine HF 105F 1 high current 30A power relay stable and reliable performance the maximum power can support 2000W Features 1 Delay start the first relay is connected at the moment of power on and then the current is limited by the NTC thermistor After a delay the main relay is turned on to realize the soft start function Suppress the inrush current of the power amplifier because the power of the class A and high power amplifier transformer is large the load impedance is extremely low and the capacity of the power supply filter capacitor is too large resulting in excessive current of the power amplifier when the power is turned on which easily damages the rectifier bridge
