PSS-B AC 150V to 280V Power Soft Start Board for HiFi Audio Amplifier Speaker Finished Board
Specification:
Name: Power Soft Start Board
Model: PSS-B
Size: 76mm*58mm
Fixed hole spacing: 70mm*52mm
Power supply voltage range: AC 150V to 280V
Scope of application: suitable for high-end audio power input, or other high-start current machine applications. The use power is suitable within 6000W
Features:
1. Can be use with touch switch or self-locking switch to realize long-distance ultra-small current control (<5mA).
2. Adopt advanced power technology to effectively reduce standby power consumption, standby power <0.1W. The board does not use ultra-small power transformers for power supply, which effectively improves stability.
3. Use the original American TE small power consumption and high current relay, the working power consumption is about 2W, the working current of the relay can reach 32A, and it can easily drive the electrical appliances within 6000W.
4. Use 2 high-power NTC resistors in series to effectively reduce the startup impact current.
5. The use of advanced patch installation technology effectively reduces the board size.
6. Humanized design, input with 4.8mm power cord, direct plug-in power socket, output using 6.3 plug spring, transformer can be plug-in, without welding.
Working Principle:
At the beginning of power-on, the thermistor with negative temperature coefficient is used to supply power to the load to limit the instantaneous current. As the temperature of the thermistor rises, the resistance decreases, and the load is close to the normal working state, and the relay is closed after about 3-5 seconds , short-circuit the thermistor, the power supply will directly supply power to the load through the relay contacts, and the load will enter the normal working state. This effectively suppresses the impact of the surge current on the line and other electrical appliances, as well as avoids the load's instantaneous high current impact and extends the load life.

1 x Power Soft Start Board
Note:
-This board is a finished board and has been debugged.
-This soft start board does not comes with switch and indicator.
-The soft start board is only used to limit the start-up current to prevent shock, and it is powered on when it is turned on. It is not a delay switch. If you need to turn on the power for a period of time, please use a delay switch.
