1000W 220V Power Amplifier Protection Board Power Delay Soft Start Circuit

Description

• 1000W 220V Power Amplifier Protection Board Power Delay Soft Start Circuit

Amplifier power delay soft start protection board Assembled:

within 1000W transformer to use.

Just power 4pcs 5w 12ohm power resistors limiting the buck 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 resistor 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 shock.

Note: The circuit hoard part element is disassemble products, finished boards detect

Package Included:
1 x Amplifier power delay soft start protection board Assembled
