Note: The correct wiring sequence is: the power--switch--soft start--load
Power Soft-start Board high-power 100A high-current Relay For Class A power amplifier or other large starting current machine
The board uses 100A large current RGL relay, silver contacts pure copper connection, durable!
No additional auxiliary add power supply, only two terminals, one connected to the power input (before a switch control), one output Connect Load, Easy to use.
Size: 67mmX61mmX30mm (high), ultra-small size
Scope of application:
Suitable for high-grade audio power input,Isolation transformer or other large starting Current Machine applications.
The power is suitable for use within 1500W
Power supply voltage adaptation range: AC 150V to 280V.
The function of the soft start board is to reduce the impact current at the moment of starting, in order to reduce the impact of the machine on the power grid and prolong the life of the switch. This board uses an ultra-large current (100A) pure copper foot relay and a large thermistor NTC 20D-20 to effectively protect the machine against excessive starting current.
This board does not require an auxiliary power supply. There are only two terminals, one is connected to the power input (before the switch is controlled), and one output is connected to the load. It is very convenient to use.
When the power is turned on, the negative temperature coefficient thermistor supplies power to the load. As the temperature of the thermistor increases, the resistance value decreases and the voltage rises slowly, effectively suppressing the surge current impact on the circuit and other electrical appliances. Impact.
After about 2 seconds, the relay pulls in and short-circuits the thermistor. The power supply will directly supply power to the load through the relay contacts, and the load will enter the normal operating state.
