Amplifier Power Delay Soft Start Protection Board For 220V 1000W Transformer Audio Amplifier AMP DIY

Amplifier power delay soft start protection board Aembled: Plate size 89 * 80mm, highmdashfrequency dual-panel gla, thine 2mm. within 1000W transformer to use. Just power 4pcs 5w 12ohm power s limiting the bu by the board, after a few seconds delay, the line relay connected 220V, 220V voltage can significantly reduce the impact of power transformers, highmdashcapacity electrolysis, rectifier diode its softmdashstart feature is also suitable for tube amplifier, so that reduce the impact of the tube filament voltage slowly upgrade. Circuit delay time is determined by the size R8 and C5. R4, R5, R6, R7 in series power should be the same as load power, better effect, can greatly reduce the impact of high current transformer caused a powermdashup. Note: This circuit board with 220V, the board shall not touch any components to prevent electrical sho. Aemble components, Nian relay. Replace the board delay relay RC element can he changed onmdashtime. Note: The circuit hoard part element is disaemble products, finished boards detect normal del ivery.
