Description

100% Brand New and High Quality
Name: High Power Power Soft Start Circuit Board
Relay: RGL high-power super-current 100A pure copper feet relay
Size: 67mmX61mmX30mm (high), ultra-small size
Scope: suitable for high-end audio power input, or other large start current machine applications. Use power suitable for within 2200W.The long-term load is best within 1200W!
Power supply voltage to adapt to the range: AC 150V to 280V.
Note: This product is not suitable for motors!
Main feature:
The soft-start board function is to reduce the instantaneous impact current to reduce the machine's impact on the grid and extend the life of the switch. This board uses ultra-high current (100A) pure copper foot relay and oversized thermistor NTC 20D-20, which effectively protects the machine from excessive startup current.
This board does not need auxiliary power supply, only two terminals, one connected to the power input (before you can connect a switch control), an output load, the use of very convenient.
Working principle:
Turn on the power supply early, through the negative temperature coefficient of the thermistor to the load power supply, with the thermistor temperature increases, the resistance decreases, the voltage rises slowly, thus effectively suppress the surge current on the impact of the line and other electrical Impact. About 5 seconds after the relay pull, short-circuit thermistor, the power supply through the relay contacts directly to the load power supply, load into the normal working condition.
