Description
Class A Amplifier Soft Start Circuit Board 1000W Power Delay Soft Starter Temperature Surge Current Protection Board
Product Description
1000W high-power power supply/Class A power amplifier board delay soft start temperature surge current protection board buffer board
Feature
1. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. First-class PCB quality, first-class production technology. 2, Suitable for all kinds of Class A or high-power amplifiers, the maximum power is 1000W. 3. Suppress the instantaneous surge current when the power amplifier is turned on. Due to the high power of the Class A and high-power power amplifier transformers, the extremely low load impedance and the large capacity of the power supply filter capacitor, the current is too large at the moment the power amplifier is turned on, and the rectifier bridge and the filter capacitor are easily damaged. 4. When the temperature of the radiator of the power amplifier board exceeds 75 degrees, the board can immediately cut off the power supply to prevent the power amplifier from overheating and burning. The power amplifier can not be restarted until the temperature of the radiator drops below 75 degrees, otherwise the power amplifier cannot be turned on. 5. The delay time can be adjusted from 0.1 to 8 seconds 6, There is no switch function, it can work when connected to the power supply!
