Description

Class A and B Digital High-Power Professional Power Supply Soft Start Board Parameter: Working voltage: AC150V-250V Output current: 25A Output power: 4000W Power consumption: <2W Dimensions: 66. 6mX62mm Application range: high power amplifier, Machines with high starting current. Features: 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 when the power is turned on. As the temperature of the thermistor rises, the resistance decreases, and the load is close to the normal working state. After about 3-5 seconds, the relay is closed. , 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. Thereby, the impact of the surge current on the line and the impact on other electrical appliances is effectively suppressed, and the instantaneous high current impact of the load is avoided and the life of the load is prolonged. Note: 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. If it needs to be powered on for a period of time before powering on and there is no need to limit the power on current, it is a delay switch, and this board can be removed with NTC20D-25.
